Unable to push to github with EGIT

Question

I have been trying to configure Eclipse (Oxygen) to be able to push to a repository on github, but to no avail. I have been trying many different configurations and using the command line, TortiseGit and Atlassian Sourcetree. I have had varying levels of success with all the others, but not with EGIT on Eclipse. I can clone the repo and import it. I can pull changes from it. But when go to push I always get the same problem, a "Not authorized" error. I have tried using _netrc, ssh keys, and passwords, all to no avail. I have tried following the instruction on all of the other questions of a similar nature I could find on stackoverflow, also with no joy. I don't know what else to try.

Answer 1

Follow the EGit push upstream section, using https, and entering your GitHub username and password, using an https (not ssh) URL:

https://github.com/<yourUsernameOnGitHub>/<yourRepo>

Make sure 2FA is not activated (or you would need a personal token) and that your password does not include any special characters.

Make sure you are pushing to a repo that you own.

Double-check if you have a git credential helper:

git config credential.helper.

If you see manager, open your Windows Credential Manager:

See if you had an entry in there with older credentials:

You could delete them and try again.
