What is two-step verification?
Two-step verification (2SV, also known as two-factor authentication) adds security by requiring an extra step when you sign in to your account or try to edit sensitive information like your password. We support these 2SV methods:
| 2SV method | Security level | When you log in... |
|---|---|---|
| SMS text message | Good | We'll text you a 6-digit code you must enter. You can't sign in if you don't receive the text. |
| Authenticator app, like Google Authenticator or Authy, on your phone or other device | Better | You must enter the code that the app shows you. You can't sign in if you don't have access to the app. |
| Hardware security key, such as a Yubikey or Google Titan | Best | You must insert the hardware key, otherwise you won't be able to sign in. Make sure you also add a different backup method so support can still verify your identity. |
Set a backup 2SV method
To minimize hassle when something goes wrong (like losing your phone), set a backup 2SV method. When you enable 2SV, set the backup at the same time.
Note: For best results, set your backup on a different device. For example, if an authenticator app on your laptop is your main 2SV, set SMS on your mobile phone as the backup method.
