How to change login credentials for Github?

[Gerhard_Mueller]

Github will soon change its login credentials:

"Basic authentication using a password to the API is deprecated and will soon no longer work. Visit https://developer.github.com/changes/2020-02-14-deprecating-password-auth/ for more information around suggested workarounds and removal dates."

I have tried to change to OAuth but it does not work. I always get this when i try a push:

"Pushing to https://github.com/CarCode/Cocoa-OCPN
remote: Permission to CarCode/Cocoa-OCPN.git denied to CarCode.
fatal: unable to access 'https://github.com/CarCode/Cocoa-OCPN/': The requested URL returned error: 403"

Where do I find any information to connect Sourcetree to Github with the new authentication? Or is that not supported by Sourcetree? I use version 4.0.1 for macOS.

I guess this answer might help you.

In my case, I was able to rather simply switch to the new authentication (using personal token) which now seems to work (without sending me any depreciation notice).

Thank you, got it now.
