Enable 2FA Globally

Two-Factor Authentication (2FA) enhances security by adding a second step to the login process. It combines something that you know (for example, your password) with a second factor, typically from something that you have (for example, your phone). Requiring both to log in decreases the threat of a leaked password.

For more information, see Two-Factor Authentication.
