When I try to submit Pset1, in the terminal, it always does this:

GitHub username: A***********8144
GitHub password: ***************
Verifying......
Make sure your username and/or password are valid and submit50 is enabled for your account. To enable submit50, please go to https://submit.cs50.io in your web
browser and try again. If you're using GitHub two-factor authentication, you'll need to create and use a personal access token with the "repo" scope instead of your
password. See https://cs50.ly/github-2fa for more information!
Submission cancelled.
