Using Two-Factor Authentication

Many user login authentication require one-time passwords (OTP). SonicOS provides authentication through:

• One-Time Password (OTP) sent to the user by email

• Time-Based One-Time Password (TOTP) authentication using an authenticator application

  To use this feature:

  • Users must download a TOTP client app (such as Google Authenticator, DUO, or Microsoft Authenticator) on their mobile device.
  • You must select TOTP from the One-time password method list on the User Settings page.
