#credentials

This problem is caused by windows saving credentials, like a password manager. Once you login to github via Intellij these credentials are saved in windows and everytime you connect to your github account it will use the saved credentials instead of the written ones. To remove the credentials in windows go to Control Panel, then click on User Accounts. In this window click on Credential Manager, the git credentials should be under Windows Credentials. Find the credentials that you need, click on them and then click on remove.
