Adding & Updating GitHub Access Token on Mac

Using an Access Token for the first time

Follow the instructions on Github to Create an Access Token in Github

Configure Git to use the osxkeychain

By default, git credentials are not cached so you need to tell Git if you want to avoid having to provide them each time Github requires you to authenticate. On Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account.

You can tell Git you want to store credentials in the osxkeychain by running the following:-

git config --global credential.helper osxkeychain

Add your access token to the osxkeychain

Now issue a command to interract with Github which requires authentication, eg. git clone or git pull. When you are prompted to supply your Password for '': you enter your access token instead. Your token should now get cached in the osxkeychain automatically.

$ git clone

Cloning into 'repo'...
Username for '': your_github_username
Password for '': your_access_token

Updating an existing Access Token

Regenerate token on Github

If your existing token has expired, or been revoked, or you are on a new machine and do not have access to the existing token then you can regerate a new one in the Github console Settings -> Developer settings -> Personal access tokens.

Remove an existing token from your Mac keychain

You can remove an existing password or token stored in the osxkeychain using the following command.

$ git credential-osxkeychain erase ↵ ↵
protocol=https ↵

You should now be prompted for your Github credentials when attempting a git pull/clone/push etc and your token should automatically get stored in the osxkeychain. If subsequent calls to Github repeatedly prompt you for your credentials then likely the credential.helper is not set - see next section.


$ git pull

remote: Invalid username or password.
fatal: Authentication failed for ''

If authentication fails and you are not prompted to enter your credentials, like in the above example, or you are repeatedly challenged by Github for your credentials, then check if you have the credential.helper set.

git config --global credential.helper

If not, or it is set to something other than osxkeychain, then update/set it.

git config --global --unset credential.helper
git config --global credential.helper osxkeychain

Then try again and you should now be prompted for your credentials.

$ git clone

Cloning into 'repo'...
Username for '': your_github_username
Password for '': your_access_token

Ensure you provide your access token rather than password when prompted.

Thanks. The $ commands did not work for me, I just read and re-read the steps and analysed the errors, and it worked. Took like 10 minutes; thanks for the comprehensive guide!

Might take some trial and error especially for people new with using Terminal, but it'll work!
