Samsung has built in finger sensors, you can use a pointer finger, your non-dominant thumb, heck your toe to be able to unlock your phone.

@lesha33 Use passwords which are long, complex, and not anything that some who knows you can guess. Use a password manager to keep track of all of your passwords. The 1Password app is highly rated. It can not only track your passwords but it can recommend strong random passwords to use.

Only use a password. Make sure its a strong password he won't guess. He could use your finger for unlock while your sleeping so don't use that.
