• Authenticator is an app that generates 2FA codes (6 random numbers that change every 30 seconds) and is designed to let only you log into your account, even if someone else knows your password.

• When you log in, you need to verify 2 factors using 2FA, you must use Authenticator to get the login code.

• The stall on MMO Grocery sells products that often come with 2FA, use this app to get the login code.
