Forgot my screen lock password Galaxy Note4

I always use the fingerprint opener, but have lost that option. I tried the "devicemanager?hl=en&u=0" listed in another thread, and was able to ring my phone, and attempted to reset the password. but it just won't work! I have tons of documents and poetry on my Note, and don't want to lose it. Please help me!

Welcome to Android Central! Are you saying you forgot the backup password? That's pretty important to remember, since the fingerprint scanner can fail like this. If you fail the unlock enough times, does it ask you for your Google credentials?
