Resetting Fingerprint scan

How did you get the phone to go back to the fingerprint scan? My phone wants the alternative password and the one I remember entering is not working. I can not afford to loose my data with a hard reset. I need to go back to the fingerprint scanner. I tried the android device manager (Google) but it still asks for my alternative password and not my Google password.
 
I logged into my Samsung account and there is a disable password/screen lock in the locate my phone menu. This helped me!
