Two-factor authentication (2FA) not working
Host
The Host is a remote module installed on a target (i.e. remote) PC. This module works for both unattended and attended access.
Symptoms
You cannot logon to the Host using the one-time password from the mobile authenticator app. The 2-factor authentication (2-step verification) code is rejected as incorrect or the one-time password from the authentication app only starts working when the next OTP is already active.
Common issues and their solutions
The phone with the authenticator app is out of sync with the Host PC
Make sure the phone with the authenticator app and the Host PC both synchronize their time from an online source. Double check if the Windows Time Service (w32tm) is set up correctly on the Host machine.
Wrong token stored on the remote PC
The problem might occur if the wrong token is stored on the remote PC.
Try following these steps:
- Open the Windows Run dialog, type in
regedit.exeto open the Windows registry editor. - Locate the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Usoris\Remote Utilities Host\Host\Parametersand delete it. - Reinstall the Host from the vanilla Host installer or your custom Host installer.
