Hello, I cannot log into my HUD account and have an exam in 3 hrs. I'm not sure which way is best to proceed. Last night I logged in utilizing dual authenticator step but I did not download an app, I simply scanned QR code and it prompted me to pick one of my phones passwords and it logged me in. It also sent me a confirmation email saying thanks for setting up. Now I can't log in cause I don't know how to generate a 6 digit pin and also don't know which app is needed to do so. PLEASE HELP
