Jenkins blue ocean change github access token

Steps to delete the Access-Token:

1. Go to the 'old' interface (i.e. not Blue Ocean)
2. Click on your username in the top right
3. Click on Credentials on the left

• You should see an entry with the domain blueocean-github-domain the id github and the name <username>/****** (Github Access Token).

Delete it.

Afterward, BlueOcean will ask for an Access Token again, when using "Github" as the source.
