About this app

Keep every account safe with Authenticator, a fast and secure two-factor authentication (2FA) app that generates verification codes right on your phone — no internet needed.

🔐 WHAT IS AN AUTHENTICATOR APP?
An authenticator adds a second layer of security to your logins. After your password, you enter a 6-digit one-time password (OTP) that refreshes every 30 seconds. Only your phone can create it, so no one can break in — even if they steal your password.
