Background

Currently, Netlify login tokens are stored in plain text in a json file on disk. This can be read and exfiltrated by malicious actors with disk read access to a user's machine. Avoiding this may limit the blast radius of a breach or agent prompt injection attack.

Summary

This PR adds support for reading and writing them to the OS's native secure keychain storage.

This works on macOS (Keychain), Windows (Credential Manager, built-in), and Linux (Secret Service, built-in to GNOME/KDE, installable elsewhere). The exact user-facing behaviour (prompting for a password/fingerprint/etc.) varies by platform and configuration; it doesn't affect us.

Details

Here's the new behaviour:

  • By default, logging in stores the new token in the OS keychain.
  • Once a token is in the OS keychain, that's what will be read.
  • If a plain text token is present, it continues to work the same before.
  • Whenever the opportunity arises (a user running an interactive command requiring auth, no
    --json, no --silent, not in CI, in a TTY, etc.) we prompt the user asking them if we may
    migrate their plaintext token to keychain storage. If approved, we initiate a fresh login, which
    stores the new token in the OS keychain, then we delete the plain text token.
  • When OS keychain storage is not available, we quietly fall through to plain text storage. We never
    prompt to migrate in this case.
  • If writing to the OS keychain fails, we faill through to plain text.
  • Edge case: In the event that a user somehow ends up with both a plaintext token and a keychain token, the
    plaintext token takes precedence.
  • As an escape hatch, NETLIFY_USE_LEGACY_AUTH_STORAGE=1 may be set to disable OS keychain storage
    entirely.

Most of the above is transparent. I tried to add helpful information to --debug mode.

The migration copy:

  Your Netlify auth token is currently stored in plaintext at
  /Users/…/Library/Preferences/netlify/config.json.
  The CLI can move it to your OS keychain (more secure). Your operating
  system may prompt you to allow access.

  ? Move the token to the keychain now? (Y/n)

"Yes" migrates and clears the plaintext entry. "No" is persisted (auth.keychainMigrationDeclined) so we don't nag again, with a hint to run netlify logout && netlify login to revisit at a later time.

NETLIFY_USE_LEGACY_AUTH_STORAGE=1 skips the keychain entirely on both read and write.

The token storage type is printed in the output of netlify status for convenience.

Plain text storage may be removed in a future major, but we have no current such plans.

So we can track relative usage of the two token storage mechanisms, the cli:command telemetry event now has an authTokenSource attribute, and new events user_authTokenStored and user_authTokenMigrationDeclined are emitted.

Notes

See netlify/primitives#830, which added the core capability.

Supersedes #8273

Summary

Summary by CodeRabbit

  • New Features
    • Login now stores authentication tokens in the operating system’s secure keychain when available. An environment variable can opt into legacy plaintext storage.
    • Existing tokens in the config file can be migrated to the keychain.
    • The status command shows where the authentication token is stored, including the source in JSON output.
    • Usage telemetry reports the token source, but never sends the token itself.
  • Documentation
    • Updated login and telemetry documentation to describe token storage and reporting.

The CLI now stores authentication tokens in the OS keychain when available and can migrate tokens from the legacy config file. It reports token storage sources in status output and command telemetry. Login waits for token storage to finish. New tests cover storage, migration, and reporting, and the integration-test matrix includes macOS and Windows for the specified branch.

Revert the temporary feature-branch matrix condition before merge.

The Revert before merging note still applies. The feature-branch condition runs the macOS and Windows matrix only for this pull request. After merge, the branch name no longer matches. Ordinary pull requests then run Ubuntu only, unless another workflow covers these platforms.

Suggested fix
-          # XXX(serhalp): also run the macOS + Windows matrix on this branch so we can verify the new keychain code
-          # paths before merge.
-          # Revert before merging.
-          if [[ "$HEAD_REF" == release-please--* || "$HEAD_REF" == "serhalp/feat/native-token-keychain-storage" ]]; then
+          if [[ "$HEAD_REF" == release-please--* ]]; then

I can prepare this revert once the macOS and Windows runs on this branch pass.

nit: Is "OS" going to be understood by all types of audience? Would "operating system" be easier?
