I have exactly the same problem. I can't login my IDNotify account through TurboTax anymore, it says "We could not log you in with single-sign on. Enter your username and password". My TurboTax login and password don't work for IDNotify. I tried to reset my password on https://portal.idnotify.com/forgot-password multiple times, but I never received an email from IDNotify with a link to reset the password. Yesterday I called IDNotify five times and each time they redirected my call to TurboTax. And each time, TurboTax representatives said that I have to contact IDNotify. This is an endless loop.
