This article demonstrates how to set up 2-Step Authentication for the router’s remote access, and add a layer of security to the router.
When 2-Step Authentication is enabled, the Internet user will not only need the administrator password but also the Auth-Code sent to the specific phone number or email address, to log into the router’s management page.
Note: 2-Step Authentication only supports login from WAN interfaces, does not support admin accounts login on LAN.
1.) To send the Auth-Code via Mail, create a Mail server profile at Objects Setting >> SMS / Mail Service Object >> Mail Server page
On the Gmail account enable the Less secure app access settings.
Please note that Less secure is not available if the two-factor authentication is enabled.
2.) At System Maintenance >> Administrator Password Setup page,
Enable “Use only advanced authentication method for Admin “WAN” login”
Choose 2-Step Authentication
Select Mail Profile to receive the authentication code
Click OK to save
This is what you received in your mailbox for the authentication code.
