How to turn on two-factor authentication
Privacy and security 1:16
Add an authenticator app or emailed codes to your login. The authenticator route also gives you ten recovery codes, shown once, and those are what get you back in if you lose the device.
- 1 Open Profile and find Two-factor.
- 2 Choose Authenticator app and scan the QR code with your app.
- 3 Enter the code your app shows to switch it on.
- 4 Save the ten recovery codes somewhere safe; they are shown once and never again.
- 5 Choose Email code instead if you would rather receive a code at each login.
A password alone isn’t enough. Let’s add a second factor.
Open Profile, and find Two-factor. Choose Authenticator app.
Scan the QR code with your app. Enter the code it shows, and it’s on.
Now the recovery codes. Ten of them, shown once. Save them somewhere safe.
Prefer email? Choose Email code instead, and a code arrives each time you log in.
From now on, logging in asks for your password, and then the code.
