These apps normally have an “Add account” menu option where you can scan the QR code provided by dRofus. Once this is set up you can press “Click here to continue”.
Logging in with 2FA
After 2FA is set up, whenever the user signs in after she has entered the username and password, she will be prompted for a one-time password. Open the app you paired your dRofus account with and click on the account and a one time password is shown.
If you check the option “Keep me signed in on this device“ you will not have to go though this step until you choose to sign out.
If you have lost your phone or need to reset / pair a new device the only option currently is to contact your dRofus administrator and ask them to reset the 2FA in the admin system. You are then prompted with the “pair a device” step again.
