is there any way to unlock the screen on a Samsung s6 without a hard reset and loosing everything

[AC Question]

My grandson changed his password for his samsung s6 and has now forgotten it.
Is there anyway to unlock the screen and change the password without loosing every thing on your phone.

The normal way is to reset it (using his Google login and password) and restore from his backup. Maybe this will teach him to keep his phone backed up.
