@backstage/plugin-auth-backend-module-guest-provider
minor

Adds a new guest provider that maps guest users to actual tokens. This also shifts the default guest login to user:development/guest to reduce overlap with your production/real data. To change that (or set it back to the old default, use the new auth.providers.guest.userEntityRef config key) like so,

auth:
  providers:
    guest:
      userEntityRef: user:default/guest

This also adds a new property to control the ownership entity refs,

auth:
  providers:
    guest:
      ownershipEntityRefs:
        - guests
        - development/custom
