How to turn on two-factor authentication
Privacy and security 1:16
Add an authenticator app or emailed codes to your login, and keep the ten recovery codes the authenticator route shows once, because they get you back in. Choose email instead and a new code arrives each time you log in.
- 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.
