Git Authentication Failure When Pushing to GitHub Repository

Problem

After enabled 2FA on my GitHub account, I received the following authentication failure while doing a git push to my branch:

Notice that the error states that support for password authentication was removed on January 13, 2024.

Solution

With 2FA (Two-Factor Authentication) enabled in your GitHub account, you will not be able to push via HTTPS using your account password. Instead you will need to provide your 2FA authentication code.

A simple workaround is to switch from using HTTPS to SSH. You can do this by navigating to the .git/ directory and opening the config file. The image below displays the following modifications:

• Comment out the HTTPS URL
• Insert the SSH URL
• Insert user section containing name and email

You can retrieve the SSH url from the GitHub repository, as shown below:
