Two-factor authentication
Protect your account with an authenticator app, with SMS as the fallback.
Account & security
Two-factor authentication (2FA) asks for a one-time code on top of your password, so a leaked password alone is not enough to get in.
Turn on 2FA
Open security settings
Settings → Account → Two-factor authentication.
Scan the QR code
Use any authenticator app (the setup key can also be entered manually).
Confirm with a code
Enter the six-digit code from the app to finish setup.
What if I cannot use my authenticator app?
If your account has a verified phone number, you can have a code sent by SMS at sign-in instead. The sign-in screen also has a recovery option if you have lost access to both.
