When we have issues to "Implement RFC-###" it would be helpful to put the RFC title in the issue title: "Implement RFC-007 Passwordless authentication for Git repositories"

If you want to put something else in, as you did here, we should at least put it in that first line, so instead of "This issue tracks the implementation of RFC-007" ... you'd save most people a click if it said "This issue tracks the implementation of RFC-007 Passwordless authentication for Git repositories"

I have removed CodeCommit as this service has been shutdown by AWS.

Sorry to bother guys, I've just created a request about kinda this topic as I was redirected from the documentation directly to the issue template creation.

But, wouldn't it OIDC/OAuth2 standard implementation belong onto this as a method for GIT authentication against IaC for gitea/gitlab/forgejo/others too?

Hello!
The issue states for all controllers but does this include the notification-controller? i'm trying to use the GithubDispatch provider in my company but since it allows only PAT token, it's a bit complicated to negociate with the security team.

@qzmiro I agree that notification-controller should work with GitHub App auth for commit status updates and workflow dispatch. Can you please open an issue in NC repo for these two?
