Tweek users/apps are recognized as pair of group+user commonly refered as subject.
Tweek can map JWT token from external systems (OIDC/OAUTH2) to a subject by using a subject extraction policy based on OpenPolicyAgent’s (https://openpolicyagent.org) Rego language. Tweek can login and verify tokens form multiple multiple external OIDC providers.
A common use case is to use an external OIDC provider such as Google/Azure/Auth0 for auditing and managing access for Tweek editor. Client apps (browser/mobile) can use the same mechanism for fetching values or writing to context. Tweek also support credentials creation for external apps. (pair of client-id, client-secret)
Additionally, it’s possible to generate an admin token by signing a JWT token with the publishing repo private key which have full access to all Tweek api.
