How do I turn on two-factor authentication?

Two-factor is for accounts that sign in with a Fiilar password. Go to Account > Login & security > Two-factor authentication and tap Turn on two-factor. Add Fiilar to your authenticator app with the QR code or setup key, tap I have added it, then enter a code from the app.

Save your recovery codes somewhere safe. Get new recovery codes replaces the old set. If you turn two-factor off, your recovery codes stop working.

If you sign in with a social account, your sign-in provider handles this instead.
