Clear Git Credentials Cache
If you’ve previously saved your credentials using Git’s credential helper, you might need to clear the cache. Use the following command:
git credential-cache exit
Authenticate on GitHub with 2FA
Go to Settings:
Navigate to your GitHub account settings by clicking on your profile picture in the top right corner of the GitHub interface, then selecting “Settings” from the dropdown menu.
Access Developer Settings:
In the left sidebar of your GitHub settings, scroll down and click on “Developer settings.”
Select Personal Access Tokens:
Under “Developer settings,” click on “Personal access tokens.” This will take you to the page where you can manage your personal access tokens.
Generate a New Token:
On the “Personal access tokens” page, click on the “Generate new token” button. You may be prompted to enter your GitHub password to proceed.
Configure Token Settings:
Give your token a descriptive name so you can easily recognize its purpose later. Then, select the scopes (permissions) that your token requires based on the actions you’ll be performing. For example, if you’re only pushing code to repositories, you only need to select the “repo” scope.
Generate and Copy Token: After configuring the token settings, click on the “Generate token” button. Once the token is generated, make sure to copy it immediately. GitHub will not display the token again for security reasons.
Use the Token for Authentication:
When prompted for credentials on the command line, instead of entering your GitHub password, paste the personal access token you just generated into the “Password” field. Your username remains the same.
