[git] GitLab remote: HTTP Basic: Access denied and fatal Authentication

It is certainly a bug, ssh works with one of my machines but not the other. I solved it, follow these.

  1. Generate an access token with never expire date, and select all the options available.
  2. Remove the existing SSH keys.
  3. Clone the repo with the https instead of ssh.
  4. Use the username but use the generated access token instead of password.

alternatively you can set remote to http by using this command in the existing repo, and use this command git remote set-url origin https://gitlab.com/[username]/[repo-name].git
