Hello Tim,
I'm glad to hear we were able to help and it worked for you!
Unfortunately, deleting the entire Host's settings key from the registry is the only way to clean up the incorrect 2FA token from your Host machine.
However, you can save some time when re-configuring your Hosts by generating a custom
One-Click installer or
Standard MSI installation package via our
MSI Configurator Tool - this can help to speed up the process of re-configuring Hosts, since you can also update the Host settings remotely using the
Remote Install Tool and the Standard MSI package.
In addition, please note that if you enable 2-step verification during MSI configuration you’ll be using the same security code for all the Hosts that you deployed using your custom build, i.e. the 2FA code in your authenticator app will be the same for all Hosts installed via this custom installer.
Hope that helps.
