I have a project hosted on GitHub. I fail when trying to push my modifications on the master. I always get the following error message
Password for 'https://git@github.com':
remote: Invalid username or password.
fatal: Authentication failed for 'https://git@github.com/eurydyce/MDANSE.git/'
However, setting my ssh key to github seems ok. Indeed, when I do a ssh -T git@github.com I get
Hi eurydyce! You've successfully authenticated, but GitHub does not provide shell access.
Which seems to indicate that everything is OK from that side (eurydyce being my github username). I strictly followed the instructions given on github and the recommendations of many stack discussion but no way. Would you have any idea of what I may have done wrong?
After enabling Two Factor Authentication (2FA), you may see something like this when attempting to use git clone, git fetch, git pull or git push:
$ git push origin master
Username for 'https://github.com': your_user_name
Password for 'https://your_user_name@github.com':
remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/your_user_name/repo_name.git/'
Why this is happening
From the GitHub Help documentation:
After 2FA is enabled you will need to enter a personal access token instead of a 2FA code and your GitHub password.
…
For example, when you access a repository using Git on the command line using commands like git clone, git fetch, git pull or git push with HTTPS URLs, you must provide your GitHub username and your personal access token when prompted for a username and password. The command line prompt won’t specify that you should enter your personal access token when it asks for your password.
How to fix it
- Generate a Personal Access Token. (Detailed guide on Creating a personal access token for the command line.)
- Copy the Personal Access Token.
- Re-attempt the command you were trying and use Personal Access Token in the place of your password.
