Additional Notes

  • Magic link tokens expire after 15 minutes (configurable)
  • Tokens are single-use and marked as used immediately upon validation
  • Token storage uses SHA-256 hashing for security
  • Supports existing MFA flow when user has MFA enabled
  • Supports device trust/approval flow for new devices
  • Email enumeration protection: always returns success message regardless of whether email exists

Created MagicLinkToken entity for passwordless authentication following
PasswordResetToken pattern:
- Token generation using cryptographically secure random bytes (32 bytes)
- SHA256 hashing for secure token storage
- 15-minute expiration window (configurable)
- Single-use validation with IsUsed/UsedAt tracking
- Token validation against stored hash
- Inherits from BaseEntity for standard Id/CreatedAt/UpdatedAt fields

Simplified compared to PasswordResetToken (removed code-based auth).
Implemented MagicLinkService following PasswordResetService pattern:
- CreateMagicLinkAsync with collision prevention (3 retries)
- ValidateTokenAsync for token validation
- MarkAsUsedAsync for single-use enforcement
- InvalidateAllTokensAsync for user token invalidation
- SHA256 token hashing for secure comparison
- 15-minute expiration (configurable via Auth:MagicLinkExpiryMinutes)
- Comprehensive logging via ILogger

Build verified: 0 errors, 0 warnings
Created RequestMagicLink CQRS command with handler and validator following ForgotPassword pattern:
- RequestMagicLinkCommand: Command with email, captchaToken, ipAddress parameters
- RequestMagicLinkHandler: Handler with captcha validation, user lookup, token creation, email sending, audit logging, anti-enumeration response
- RequestMagicLinkValidator: FluentValidation validator for email format
- Added MagicLinkRequested, MagicLinkLogin, MagicLinkLoginFailed audit actions to AuditActions
- Added SendMagicLinkAsync method to IEmailService and EmailService implementation
- Handler validates CAPTCHA, checks user exists/active/not-anonymized, creates magic link token, sends email, logs audit event
- Always returns success response to prevent email enumeration
- Build verified: 0 errors, 0 warnings
- Created LoginWithMagicLinkCommand with token and device info parameters
- Created LoginWithMagicLinkValidator for token validation
- Created LoginWithMagicLinkHandler with full authentication flow:
  * Validates magic link token via IMagicLinkService
  * Marks token as used after validation
  * Handles MFA if enabled (returns RequiresMfa response)
  * Handles MFA setup requirement for system permission users
  * Device tracking and risk scoring (new device approval flow)
  * Spoofing detection for trusted devices
  * Session creation with access and refresh tokens
  * Login pattern recording for risk analysis
  * Comprehensive audit logging
  * New location email notification
- Added MagicLinkTokenInvalidException to AuthException.cs
- Handler follows LoginHandler pattern for consistency
- Build verified successfully with 0 errors/warnings
Added magic-link subjects to both English and German subjects.json files:
- English: 'Your magic link to sign in'
- German: 'Ihr Magic Link zum Anmelden'

Note: Task spec indicated modifying EmailTemplateService.cs, but the correct
approach is to add subjects to subjects.json files, which EmailTemplateService
loads dynamically.
Created MagicLinkForm component following accept-invite-form pattern with:
- Email input field with validation
- CAPTCHA widget integration
- Submit button with loading states
- Error message display
- react-hook-form + zod validation
- useRequestMagicLink hook

Also added supporting code to make component compile:
- RequestMagicLinkRequest/Response types in @/types/auth
- requestMagicLink API function in auth-api.ts
- useRequestMagicLink hook
- createMagicLinkSchema and MagicLinkFormData in types/index.ts

Build verified successfully.
- Added MagicLinkLoginRequest type extending DeviceInfo with token and rememberMe fields
- Added magicLinkLogin function to authApi for /system/auth/magic-link/login endpoint
- Follows pattern from password-reset-api.ts with async/await and extractData helper
- Returns AuthResponse for authentication flow completion
Created useMagicLinkLogin hook following the useLogin pattern. The hook:
- Uses useMutation from react-query for API calls
- Handles MFA requirements (verification and setup)
- Handles device approval flow for risk-based authentication
- Updates auth state and navigates on successful login
- Provides callback options for different auth flows

Also exported both useRequestMagicLink and useMagicLinkLogin from the
hooks index for easy consumption.

Build verified successfully.
- Export MagicLinkForm and MagicLinkSent from auth components
- Add toggle between password and magic link login modes
- Implement state management for login mode switching
- Show MagicLinkSent component after successful magic link request
- Add translation keys for toggle buttons (useMagicLink, usePassword)
- Add missing magicLink translation keys (email, button, sending, sent, sentMessage)
Verified magic link passwordless login functionality:

✅ API Endpoints:
- POST /api/system/auth/magic-link/request returns 200
- Token generation and storage working
- Anti-enumeration implemented
- Rate limiting applied
- Audit logging functional

✅ Database:

- Token hashing (SHA256) verified
- 15-minute expiration configured
- Single-use enforcement via is_used column
- Previous tokens auto-invalidated

✅ Security Features:
- Cryptographically secure tokens (32 bytes)
- Collision prevention (3 retries)
- CAPTCHA integration (configurable)
- Rate limiting on sensitive endpoints

✅ Frontend:

- Configured Swagger to include XML comments from generated documentation file
- Magic link endpoints now documented in Swagger/OpenAPI with:
  * POST /api/system/auth/magic-link/request - Request magic link email
  * POST /api/system/auth/magic-link/login - Login with magic link token
- Both endpoints include proper summaries, request/response schemas, and status codes
- Added swagger-verification.md with verification steps
- Add MagicLinkToken entity tests (token creation, hashing, expiration, validation)
- Add RequestMagicLinkHandler tests (email handling, CAPTCHA, user states)

Created MagicLinkToken entity for passwordless authentication following
PasswordResetToken pattern:
- Token generation using cryptographically secure random bytes (32 bytes)
- SHA256 hashing for secure token storage
- 15-minute expiration window (configurable)
- Single-use validation with IsUsed/UsedAt tracking
- Token validation against stored hash
- Inherits from BaseEntity for standard Id/CreatedAt/UpdatedAt fields

Simplified compared to PasswordResetToken (removed code-based auth).

* Add MagicLinkToken EF Core configuration

* Add DbSet<MagicLinkToken> to IAppDbContext and AppDbContext

* Create and apply EF Core migration for MagicLinkToken

* Create IMagicLinkService interface

* Implement MagicLinkService with collision prevention

Implemented MagicLinkService following PasswordResetService pattern:
- CreateMagicLinkAsync with collision prevention (3 retries)
- ValidateTokenAsync for token validation
- MarkAsUsedAsync for single-use enforcement
- InvalidateAllTokensAsync for user token invalidation
- SHA256 token hashing for secure comparison
- 15-minute expiration (configurable via Auth:MagicLinkExpiryMinutes)
- Comprehensive logging via ILogger

Build verified: 0 errors, 0 warnings

* Register IMagicLinkService in DI container

* Create RequestMagicLink command, handler, and validator

Created RequestMagicLink CQRS command with handler and validator following ForgotPassword pattern:
- RequestMagicLinkCommand: Command with email, captchaToken, ipAddress parameters
- RequestMagicLinkHandler: Handler with captcha validation, user lookup, token creation, email sending, audit logging, anti-enumeration response
- RequestMagicLinkValidator: FluentValidation validator for email format
- Added MagicLinkRequested, MagicLinkLogin, MagicLinkLoginFailed audit actions to AuditActions
- Added SendMagicLinkAsync method to IEmailService and EmailService implementation
- Handler validates CAPTCHA, checks user exists/active/not-anonymized, creates magic link token, sends email, logs audit event
- Always returns success response to prevent email enumeration
- Build verified: 0 errors, 0 warnings

* Create LoginWithMagicLink command, handler, and validator

- Created LoginWithMagicLinkCommand with token and device info parameters
- Created LoginWithMagicLinkValidator for token validation
- Created LoginWithMagicLinkHandler with full authentication flow:
  * Validates magic link token via IMagicLinkService
  * Marks token as used after validation
  * Handles MFA if enabled (returns RequiresMfa response)
  * Handles MFA setup requirement for system permission users
  * Device tracking and risk scoring (new device approval flow)
  * Spoofing detection for trusted devices
  * Session creation with access and refresh tokens
  * Login pattern recording for risk analysis
  * Comprehensive audit logging
  * New location email notification
- Added MagicLinkTokenInvalidException to AuthException.cs
- Handler follows LoginHandler pattern for consistency
- Build verified successfully with 0 errors/warnings

* Create magic link email templates (English and German)

* Add email template subjects for magic link

Added magic-link subjects to both English and German subjects.json files:
- English: 'Your magic link to sign in'
- German: 'Ihr Magic Link zum Anmelden'

Note: Task spec indicated modifying EmailTemplateService.cs, but the correct
approach is to add subjects to subjects.json files, which EmailTemplateService
loads dynamically.

* Add POST /api/system/auth/magic-link/request endpoint

* Add POST /api/system/auth/magic-link/login endpoint

* Create MagicLinkForm component for requesting magic link

Created MagicLinkForm component following accept-invite-form pattern with:
- Email input field with validation
- CAPTCHA widget integration
- Submit button with loading states
- Error message display
- react-hook-form + zod validation
- useRequestMagicLink hook

Also added supporting code to make component compile:
- RequestMagicLinkRequest/Response types in @/types/auth
- requestMagicLink API function in auth-api.ts
- useRequestMagicLink hook
- createMagicLinkSchema and MagicLinkFormData in types/index.ts

Build verified successfully.

* Create MagicLinkSent component for confirmation sc

* Add magic link API functions to auth-api.ts

- Added MagicLinkLoginRequest type extending DeviceInfo with token and rememberMe fields
- Added magicLinkLogin function to authApi for /system/auth/magic-link/login endpoint
- Follows pattern from password-reset-api.ts with async/await and extractData helper
- Returns AuthResponse for authentication flow completion

* Create React hooks for magic link flow

Created useMagicLinkLogin hook following the useLogin pattern. The hook:
- Uses useMutation from react-query for API calls
- Handles MFA requirements (verification and setup)
- Handles device approval flow for risk-based authentication
- Updates auth state and navigates on successful login
- Provides callback options for different auth flows

Also exported both useRequestMagicLink and useMagicLinkLogin from the
hooks index for easy consumption.

Build verified successfully.

* Create /magic-link-login route for token validation

* Add 'Sign in with magic link' option to login page

- Export MagicLinkForm and MagicLinkSent from auth components
- Add toggle between password and magic link login modes
- Implement state management for login mode switching
- Show MagicLinkSent component after successful magic link request
- Add translation keys for toggle buttons (useMagicLink, usePassword)
- Add missing magicLink translation keys (email, button, sending, sent, sentMessage)

* Add i18n translations for magic link feature

* End-to-end magic link flow verification

* Revert "feat(frontend): move all system routes to /system/* prefix (#39)" (#40)

This reverts commit c0e2b9f.

* release: merge develop into main (#44)

* fix: add captcha.error translation and protected DbContext constructor

- Add missing `auth:captcha.error` translation key in EN and DE auth.json
- Add protected constructor to AppDbContext for DbContext inheritance support
  (required by Pro's ProDbContext which extends AppDbContext)

* Add Magic Link Passwordless Login Feature (#38)

* Create MagicLinkToken entity with token generation

Created MagicLinkToken entity for passwordless authentication following
PasswordResetToken pattern:
- Token generation using cryptographically secure random bytes (32 bytes)
- SHA256 hashing for secure token storage
- 15-minute expiration window (configurable)
- Single-use validation with IsUsed/UsedAt tracking
- Token validation against stored hash
- Inherits from BaseEntity for standard Id/CreatedAt/UpdatedAt fields

Simplified compared to PasswordResetToken (removed code-based auth).

* Add MagicLinkToken EF Core configuration

* Add DbSet<MagicLinkToken> to IAppDbContext and AppDbContext

* Create and apply EF Core migration for MagicLinkToken

* Create IMagicLinkService interface

* Implement MagicLinkService with collision prevention

Implemented MagicLinkService following PasswordResetService pattern:
- CreateMagicLinkAsync with collision prevention (3 retries)
- ValidateTokenAsync for token validation
- MarkAsUsedAsync for single-use enforcement
- InvalidateAllTokensAsync for user token invalidation
- SHA256 token hashing for secure comparison
- 15-minute expiration (configurable via Auth:MagicLinkExpiryMinutes)
- Comprehensive logging via ILogger

Build verified: 0 errors, 0 warnings

* Register IMagicLinkService in DI container

* Create RequestMagicLink command, handler, and validator

Created RequestMagicLink CQRS command with handler and validator following ForgotPassword pattern:
- RequestMagicLinkCommand: Command with email, captchaToken, ipAddress parameters
- RequestMagicLinkHandler: Handler with captcha validation, user lookup, token creation, email sending, audit logging, anti-enumeration response
- RequestMagicLinkValidator: FluentValidation validator for email format
- Added MagicLinkRequested, MagicLinkLogin, MagicLinkLoginFailed audit actions to AuditActions
- Added SendMagicLinkAsync method to IEmailService and EmailService implementation
- Handler validates CAPTCHA, checks user exists/active/not-anonymized, creates magic link token, sends email, logs audit event
- Always returns success response to prevent email enumeration
- Build verified: 0 errors, 0 warnings

* Create LoginWithMagicLink command, handler, and validator

- Created LoginWithMagicLinkCommand with token and device info parameters
- Created LoginWithMagicLinkValidator for token validation
- Created LoginWithMagicLinkHandler with full authentication flow:
  * Validates magic link token via IMagicLinkService
  * Marks token as used after validation
  * Handles MFA if enabled (returns RequiresMfa response)
  * Handles MFA setup requirement for system permission users
  * Device tracking and risk scoring (new device approval flow)
  * Spoofing detection for trusted devices
  * Session creation with access and refresh tokens
  * Login pattern recording for risk analysis
  * Comprehensive audit logging
  * New location email notification
- Added MagicLinkTokenInvalidException to AuthException.cs

* Add email template subjects for magic link

Added magic-link subjects to both English and German subjects.json files:
- English: 'Your magic link to sign in'
- German: 'Ihr Magic Link zum Anmelden'

Note: Task spec indicated modifying EmailTemplateService.cs, but the correct
approach is to add subjects to subjects.json files, which EmailTemplateService
loads dynamically.

* Add POST /api/system/auth/magic-link/request endpoint

* Add POST /api/system/auth/magic-link/login endpoint

* Create MagicLinkForm component for requesting magic link

Created MagicLinkForm component following accept-invite-form pattern with:

- Added magicLinkLogin function to authApi for /system/auth/magic-link/login endpoint
- Follows pattern from password-reset-api.ts with async/await and extractData helper
- Returns AuthResponse for authentication flow completion

* Create React hooks for magic link flow

Created useMagicLinkLogin hook following the useLogin pattern. The hook:
- Uses useMutation from react-query for API calls
- Handles MFA requirements (verification and setup)
- Handles device approval flow for risk-based authentication
- Updates auth state and navigates on successful login
- Provides callback options for different auth flows

* chore: merge main into develop (#43)

* feat(frontend): move all system routes to /system/* prefix (#39)

* Add missing captcha.error translation key

Added generic error message for captcha verification failures in both
EN and DE locales.

* fix: add captcha.error translation and protected DbContext constructor

- Add missing `auth:captcha.error` translation key in EN and DE auth.json
- Add protected constructor to AppDbContext for DbContext inheritance support
  (required by Pro's ProDbContext which extends AppDbContext)

* Add Magic Link Passwordless Login Feature (#38)

* Create MagicLinkToken entity with token generation

Created MagicLinkToken entity for passwordless authentication following
PasswordResetToken pattern:
- Token generation using cryptographically secure random bytes (32 bytes)
- SHA256 hashing for secure token storage
- 15-minute expiration window (configurable)
- Single-use validation with IsUsed/UsedAt tracking
- Token validation against stored hash
- Inherits from BaseEntity for standard Id/CreatedAt/UpdatedAt fields

Simplified compared to PasswordResetToken (removed code-based auth).

* Add MagicLinkToken EF Core configuration

* Add DbSet<MagicLinkToken> to IAppDbContext and AppDbContext

* Create and apply EF Core migration for MagicLinkToken

* Create IMagicLinkService interface

* Implement MagicLinkService with collision prevention

Implemented MagicLinkService following PasswordResetService pattern:
- CreateMagicLinkAsync with collision prevention (3 retries)
- ValidateTokenAsync for token validation
- MarkAsUsedAsync for single-use enforcement
- InvalidateAllTokensAsync for user token invalidation
- SHA256 token hashing for secure comparison
- 15-minute expiration (configurable via Auth:MagicLinkExpiryMinutes)
- Comprehensive logging via ILogger

Build verified: 0 errors, 0 warnings

* Register IMagicLinkService in DI container

* Create RequestMagicLink command, handler, and validator

Created RequestMagicLink CQRS command with handler and validator following ForgotPassword pattern:
- RequestMagicLinkCommand: Command with email, captchaToken, ipAddress parameters
- RequestMagicLinkHandler: Handler with captcha validation, user lookup, token creation, email sending, audit logging, anti-enumeration response
- RequestMagicLinkValidator: FluentValidation validator for email format
- Added MagicLinkRequested, MagicLinkLogin, MagicLinkLoginFailed audit actions to AuditActions
- Added SendMagicLinkAsync method to IEmailService and EmailService implementation
- Handler validates CAPTCHA, checks user exists/active/not-anonymized, creates magic link token, sends email, logs audit event
- Always returns success response to prevent email enumeration
- Build verified: 0 errors, 0 warnings

* Create LoginWithMagicLink command, handler, and validator

- Created LoginWithMagicLinkCommand with token and device info parameters
- Created LoginWithMagicLinkValidator for token validation
- Created LoginWithMagicLinkHandler with full authentication flow:
  * Validates magic link token via IMagicLinkService
  * Marks token as used after validation
  * Handles MFA if enabled (returns RequiresMfa response)
  * Handles MFA setup requirement for system permission users
  * Device tracking and risk scoring (new device approval flow)
  * Spoofing detection for trusted devices
  * Session creation with access and refresh tokens
  * Login pattern recording for risk analysis
  * Comprehensive audit logging
  * New location email notification
- Added MagicLinkTokenInvalidException to AuthException.cs
- Handler follows LoginHandler pattern for consistency
- Build verified successfully with 0 errors/warnings

* Create magic link email templates (English and German)

* Add email template subjects for magic link

Added magic-link subjects to both English and German subjects.json files:
- English: 'Your magic link to sign in'
- German: 'Ihr Magic Link zum Anmelden'

Note: Task spec indicated modifying EmailTemplateService.cs, but the correct
approach is to add subjects to subjects.json files, which EmailTemplateService
loads dynamically.

* Add POST /api/system/auth/magic-link/request endpoint

* Add POST /api/system/auth/magic-link/login endpoint

* Create MagicLinkForm component for requesting magic link

Created MagicLinkForm component following accept-invite-form pattern with:
- Email input field with validation
- CAPTCHA widget integration
- Submit button with loading states
- Error message display
- react-hook-form + zod validation
- useRequestMagicLink hook

Also added supporting code to make component compile:
- RequestMagicLinkRequest/Response types in @/types/auth
- requestMagicLink API function in auth-api.ts
- useRequestMagicLink hook
- createMagicLinkSchema and MagicLinkFormData in types/index.ts

Build verified successfully.

* Create MagicLinkSent component for confirmation sc

* Add magic link API functions to auth-api.ts

- Added MagicLinkLoginRequest type extending DeviceInfo with token and rememberMe fields
- Added magicLinkLogin function to authApi for /system/auth/magic-link/login endpoint
- Follows pattern from password-reset-api.ts with async/await and extractData helper
- Returns AuthResponse for authentication flow completion

* Create React hooks for magic link flow

Created useMagicLinkLogin hook following the useLogin pattern. The hook:
- Uses useMutation from react-query for API calls
- Handles MFA requirements (verification and setup)
- Handles device approval flow for risk-based authentication
- Updates auth state and navigates on successful login
- Provides callback options for different auth flows

Also exported both useRequestMagicLink and useMagicLinkLogin from the
hooks index for easy consumption.

Build verified successfully.

* Create /magic-link-login route for token validation

* Add 'Sign in with magic link' option to login page

- Export MagicLinkForm and MagicLinkSent from auth components
- Add toggle between password and magic link login modes
- Implement state management for login mode switching
- Show MagicLinkSent component after successful magic link request
- Add translation keys for toggle buttons (useMagicLink, usePassword)
- Add missing magicLink translation keys (email, button, sending, sent, sentMessage)

* Add i18n translations for magic link feature

* End-to-end magic link flow verification

Verified magic link passwordless login functionality:

✅ API Endpoints:
- POST /api/system/auth/magic-link/request returns 200
- Token generation and storage working
- Anti-enumeration implemented
- Rate limiting applied
- Audit logging functional

✅ Database:
- magic_link_tokens table operational
- Token hashing (SHA256) verified
- 15-minute expiration configured
- Single-use enforcement via is_used column
- Previous tokens auto-invalidated

✅ Security Features:
- Cryptographically secure tokens (32 bytes)
- Collision prevention (3 retries)
- CAPTCHA integration (configurable)
- Rate limiting on sensitive endpoints

✅ Frontend:
- MagicLinkForm component built
- Login page integration complete
- /magic-link-login route created
