For users without two-factor authentication enabled, GitHub now requires additional verification when you first sign in from an unrecognized device. After providing your username and password, you will be asked to provide a verification code that we will send to you via email. Once your new device has been verified, you will be signed in and will not be asked to verify the device again.
