Switching between authenticator app, SMS, and security keys

You can change your 2FA method anytime as long as you still have access to your current one.

Steps

1. Open Security → Two-factor authentication and approve the current 2FA challenge.
2. Choose Change method and pick the new one.
3. Complete the setup wizard for the new method and confirm with a test code.
4. Generate fresh backup codes — old ones stop working when the method changes.

Tip: If you travel and have spotty SMS, switch to an authenticator app so you don't get locked out abroad.
