Is there anyway to bypass the Master Reset for forgetting my Alternative password?

[jay monea]

I accidentally locked myself out of my phone today. I was using the fingerprint scanner and when I looked at my phone it said 15 unsuccessful attempts. I called Technical Support for my phone carrier and they only gave me two options , which were to use FINDMYMOBILE.SAMSUNG.COM by logging into my Samsung galaxy account or to do the Master reset. I tried to log into my account but I wasn't logged in my account on my phone, neither did I remember the password to that account because I didn't use it. There goes my luck. I even tried to do the android device manager lock phone and change password option but that didn't work either. I really really would hate to lose all my memories on my phone. It saddens me a little. The Master reset seems to be the only option left. If someone could help me in any way possible, I would greatly appreciate it. By the way, if you do so happen to fall into this same predicament and you have a galaxy phone and know your password to your samsung account you can use FINDMYMOBILE.SAMSUNG.COM to help you.
I'M ALMOST DESPERATE....PLEASEEE HELPPPP!!!!!!
