With Mobile Authenticator applications, the code to be used for 2FA login can be generated. In order for the user to make this definition, he/she must be logged in to ARKSSPR.

Users can do this with an Authenticator software that he/she will install on his mobile phone. Two authenticator applications are given below, and any application that supports time-based OTP can be used.

In the Authenticator application, the QR code is scanned with the camera on the account identification screen. The 6-digit code generated only once is entered for confirmation purposes.

If this process is done through a browser on a mobile phone, the QR code may not be scan with the camera. For this purpose, "Can't Scan QR Code?" button is clicked and manual identification can be made with the Secret Key. The code generated in the same way is entered only once for verification purposes.
