My fingerprint scanner option disappeared from my phone and I have forgotten my backup password. I have a Samsung Galaxy Alpha. How do I reset my backup password?
Before attempting to do anything on your phone, you could contact Samsung and see what they say. I'm sure YouTube or Google would also be good resources. Not sure if Samsung works the same way, but if your phone is locked and you can't remember your backup password, the phone may wipe itself, so just be careful if you get prompted about a factory reset!
