Multi-factor authentication (MFA)
You can implement two-factor authentication using hardware or software tokens. Software tokens must be linked to an authenticator app such as Sophos Authenticator or any third-party authenticator on a mobile device or tablet. When users log on, they must provide a password and a passcode.
You can turn on MFA for all users or just specific users. To turn on MFA for the default admin account, go to Administration > Device access.
Multi-factor authentication (MFA) settings
To configure MFA for users other than the default admin account, do as follows:
Under One-time password (OTP), select if you want to turn on MFA for All users or Specific users and groups.
- If you're only configuring MFA for specific users and groups, click Add users and groups, select the users and groups you want to add, and click Apply.
Turn on Generate OTP token with next sign-in. When you turn this on, users are asked to set up an authentication app on their mobile device and scan the generated QR code the next time they sign in to the user portal.
If you don't turn on Generate OTP token with next sign-in, you must configure a hardware token for each user under Issued tokens.

- User portal
- Web admin console
- SSL VPN remote access

User portal is automatically selected when Generate OTP token with next sign-in is turned on.
