+remote: Support for password authentication was removed on August 13, 2021.
+remote: Please see https://docs.github.com/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication.
+fatal: Authentication failed for 'https://github.com/<your-github-username>/my-first-blog.git/'
+```
+In this case, follow the instructions from GitHub to [create a personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-personal-access-token-classic). The token should have the 'repo' scope. Copy the value of the token, then try the git push command again. When you are prompted to enter your username and password, enter the access token instead of your password.
