Deploying without an identity service

[naturedamends]

The included identity service in the GitHub backend is in-appropriate for users who's GitHub account has access.

Therefore is it safe to deploy the admin code statically without any auth. Then turning off the current identity service and just connecting via GitHub?

Using GitHub api not git gateway.

Are there any backends supporting connecting to GitHub to get the token instead of the identity service returning the token?

Can I not just use GitHub as a custom auth provider? I don't see the point in creating my own endpoints to return the api token in the callback endpoint.
Let's say I already have a api token how can I initialise without doing any user flow?
