battery died on android needed password

[AC Question]

i had finger print scanner for lock phone, my battery died and it wanted a password to get back in. I don't know the password, i did a device manager reset password and it did not work on phone. I am still locked out, I do not want to do a factory reset due to having important texts and pictures I cannot lose. My phone is a galaxy s7. I also tried the samsung account thing and that didnt help as i have no account and cannot do what it wants me to do since i cannot get into my phone. Please help
