There are several options to bypass the Windows Logon Agent and log in to a machine when it is not authenticating properly. If there is an issue with your AuthAnvil Two Factor Auth server then that will also need to be resolved before the agent can continue working. This article outlines the process to get around the 2FA protection in case of an emergency.
If two-factor authentication is not allowing you through, your easiest bypass method is to use the Global Override Password that was created during the installation of the agent. This password should be stored securely for access in these types of situations, and there should be a workaround in place even if you are locked out of your AuthAnvil Password Server, or another password manager secured with 2FA.
Are you using an AuthAnvil RMM component such as the Kaseya Addin or the Labtech Management Pack to push out the AuthAnvil agents? You may already have a script that can run on the client machines to change the Override Password. You can also download the Override Password Utility tool from http://www.scorpionsoft.com/downloads/2fa under "Maintenance Tools".
2) Log in as a member of the Override Group
Every Windows agent has the name of an override group configured. If you do not have access to an account that is a member of this group, log in to your domain controller and simply add your user as a member so you can log in without providing your 2FA credentials.
Open up "regedit" and select File -> Connect Network Registry. Depending on your security settings, this should allow you to connect to the machine where the agent is installed and to modify the registry manually.
4) Emergency Uninstall / Disable Agent
There is a single registry key that allows the Windows Logon Agent to be loaded on the login screen. If you remove this key then the agent will not load and you can log in as normal. For Server 2008 / Windows Vista and newer operating systems, this change will apply immediately and the agent will be disabled. Older environments will have to be restarted for this change to apply.
