Ah shucks! That's no good but I'm hoping we can get you back into your phone without resetting it. After you've tried a few codes, does the phone ask you for your gmail address? If so, there could be a chance you can reset the password using your email address. If it doesn't resetting will be the only option. Please keep us posted and let us know if you need some help. Thank you.
I wanted to check-in to see if you're still having issues with your phone being locked. If so, please take a look at Mike's response above and get back to us.
Hey, rocksnotdead02. This is definitely something we'd like to help with if we can! Have you tried changing the password on Google's accounts recovery page? Does the phone say it's "locked by Find My Device", which is a Google service, or does it look like that's referring to Samsung's "Find My Mobile"? How are things going for you? I hope you were able to avoid the reset!
