Before you choose
- Check that each account, browser and device supports the key and the sign-in method you intend to use.
- Register and test both keys individually. A second unregistered key is not an account backup.
- Keep printed recovery codes separately and securely. Do not put passwords or codes into this website.
- A hardware key can help with supported account sign-in; it does not restore your SIM, bypass a carrier’s identity checks or recover an unregistered account.
