Dialog appears after OmniPass authentication during Windows Logon
After installing OmniPass on your system, you can choose to logon to Windows using OmniPass. You authenticate
with OmniPass (via master password, or an enrolled security device) and OmniPass logs you into Windows. You may,
during this OmniPass authentication, see a Login Error dialog box.
This dialog box occurs when OmniPass was unable to log you into Windows with the credentials supplied (username
and password). This could happen for any of the following reasons:
• Your Windows password has changed
• Your Windows account has been disabled
If you are having difficulties due to the first reason, you will need to update OmniPass with your changed Windows
account password. Click Update Password and you will be prompted with a dialog to reconfirm your password.
Enter the new password to your Windows user account and click OK. If the error persists, then it is unlikely the problem
is due to your Windows user account password changing.
