If your password is stolen or hacked, your personal data—and online identity—could be at risk. Two-Factor Authentication keeps thieves and hackers out, even if they have your password.
An extra layer of protection
Your first layer of protection is your password. Two-Factor Authentication adds a second layer of protection—a unique verification code that changes every time you sign in. Even if someone steals or guesses your password, they can't access your account.
Your password and your phone
When you sign in with Two-Factor Authentication, you will:
1) Enter your email and password as usual
2) Enter the verification code
Verification codes are sent to your phone via voice, text, or a free mobile app and can only be used once.
Secure and simple
Two-Factor Authentication can be turned off on a particular device for faster sign-in. We'll still ask for the code if anyone tries to sign in from another device.
