Git: force user and password prompt

Add a -v flag with your git command . e.g. git pull -v

v stands for verify .

This is most likely because you have multiple accounts, like one private, one for work with GitHub.

SOLUTION On Windows, go to Start > Credential Manager > Windows Credentials and remove GitHub creds, then try pulling or pushing again and you will be prompted to relogin into GitHub

SOLUTION OnMac, issue following on terminal:

git remote set-url origin https://[email protected]/username/repo-name.git

by replacing 'username' with your GitHub username in both places and providing your GitHub repo name.

With git config -l, I now see I have a credential.helper=osxkeychain option

That means the credential helper (initially introduced in 1.7.10) is now in effect, and will cache automatically the password for accessing a remote repository over HTTP.
(as in "GIT: Any way to set default login credentials?")

You can disable that option entirely, or only for a single repo.
