Google Authenticator App, available for Android and iOS, offers an extra layer of security for your online accounts through two-factor authentication (2FA). By generating a unique, time-sensitive one-time password (OTP), this app requires more than just your account password to grant access. The OTP, changing every 30 seconds, helps prevent unauthorized access. In addition, Google Authenticator supports other protocols like TOTP (Time-Based One-Time Password) and HOTP (HMAC-Based One-Time Password), ensuring robust protection for your digital presence.

The app produces time-based one-time passwords (TOTP), which are unique and time-limited, enhancing the security level for your accounts. Available on both Android and iOS platforms, Google Authenticator is easily accessible, no matter the device you use.
