Need a way to generate a secret.key file for anyone not developing this repo

[2bndy5]

Since the merging of the PR to enhance user management, this repo has been working exclusively on machines with the privilege of having oursecret.key file. Meaning absolutely no one else can use it to make a robot. This negates our core principal of making software that anyone can use for their robot. We need a security-friendly way to generate this secret.key file or forego the use of it when using a local database for user management
