Use these 2FA setup guides to configure authenticator apps, move verification codes to a new phone, prepare recovery options, understand passkeys, and choose tools without creating an avoidable lockout.

Back up and recover Google Authenticator

Choose the right security tools

Understand the technology before setup
What is two-factor authentication?

Understand fingerprints, facial recognition, device unlock, biometric templates, and how biometrics can authorize passkeys.
Before you change a login
- Begin from the service’s official website or app.
- Keep a trusted session open until the new sign-in method succeeds.
- Save recovery codes somewhere separate from the device being enrolled.
- Add a second recovery method when the service supports one.
- Test the new method before removing an old phone, authenticator, or security key.
- Never publish or send a setup QR code or authenticator secret.
Login screens and recovery options change. Confirm important steps against the provider’s current official documentation while completing setup.
