I forgot my phone's password. How can I change it again?

If it matters in any way, I have a samsung J3. I tried typing random passwords to see if I'd get the "Forgot your password" thing i used to get on my old Lenovo.

Did you have a google account set up on your phone?

If not, your only choice appears to be a hard reset that will delete your data

This is a program that claims to be able to bypass it
