Can I confirm that you weren't able to remove the GitHub keys from Authentication under /admin/customization/config using the UX, and so you had to access the .env files yourself?
For further actions, you may consider blocking this person and/or reporting abuse
Thank you, after removing the GitHub keys from the .env file, I am able to remove the Authentication type in the admin config.
Glad to hear you got it working!
