Update GitHub Personal Access Token on MacOS

I received an email with the subject: [GitHub] Your personal access token (classic) has expired. It happens once in a while and everytime I forget how to regenerate and update it, so I come up with a little memo for my future self.

Generate a new token

• On GitHub go Settings > Developer Settings > Personal Access Tokens or follow this link.
• Go to Generate a new token ->Generate new token (classic). Write a note and toggle repo and workflow as the scope.
• Click Generate token and copy your new token somewhere safe, like password manager. You won't find it later on GitHub, only generate a new one.

Remove the old token from keychain

In your terminal copy this command

git credential-osxkeychain erase

Hit Enter ↵. It won't show you a new line with the $, don't worry and copy the next line

host=github.com

Hit Enter ↵ and copy the last line

protocol=https

Hit Enter ↵ for the last time and that's it.

Update credentials with the new token

Use git push or git clone in the terminal, it will ask you for credentials:

Username for 'https://github.com':

Type your username and hit Enter ↵.

Password for 'https://username@github.com':

Paste your new token and hit Enter ↵.

Everything is set up, get back to work!
