Here's a very quick example of how to setup GitHub SSH keys and use them to perform Git clone, push and pull commands over a securely configured SSH connection.

GitHub also supports integration with physical security keys like Yubikey. Here’s how you can enable 2FA on your GitHub account: Log in to your GitHub account on the desktop.

Assume your GitHub account is hacked, users with weak crypto keys told SSH keys give access to projects belonging to Spotify, Yandex, and UK gov.

To confirm that your public key has been configured correctly, check the SSH and GPG link in your account settings. If no keys are listed, add your public key and try to connect to GitHub over SSH ...

Google Go to the Add a Security Key page section of My Account. Remove the key if it's already inserted. Click on the Register button. Insert your Security Key into a USB port on your computer.

A bug in the library's pseudo-random number generator allowed for the generation of duplicate RSA keys, enabling users to access other GitHub accounts secured with the same SSH key.
