Android normally secures your device by demanding a PIN, pattern, or full password. Your phone isn't useless if you forget the unlock code — you can bypass screen lock password for Samsung S7 Edge. As Google tightens security, this has become more difficult on modern versions of Android. But there's always a way to make your phone usable again, as long as you remember your Google account's username and its password. Older versions of Android — Android 4.4 KitKat and older — have an integrated way to bypass your pattern, PIN, or other password if you forget it. Google removed this feature in Android 5.0 Lollipop, so you'll have to use a different method if you have a device with a newer version of Android. To find this feature, first enter an incorrect pattern or PIN five times at the lock screen. You'll see a "Forgot pattern," "forgot PIN," or "forgot password" button appear. Tap it. You'll be prompted to enter the username and password of the Google account associated with your Android device.
I have a google account. I can login to both but neither provide the ability to reset your password, or unlock Samsung Galaxy S7 Edge without password. It seems both have completely feigned responsibility here, and as a result if anyone forgets their password then you are stuck. Unless you install some hacking program, which I assume compromises your phone in other ways.
