How To Change Samsung Galaxy A15 5G Lock Screen Password?

Setting up a lock screen is a crucial step in protecting your phone’s data. If you’re not sure how to create one on your Android™ phone, we’re here to help.

Your Android lock screen pin or password and your Google Account password are two passwords you use frequently. Keeping a good lock screen passcode is important.

Although you might not frequently enter your lock screen pin or password if you use a biometric unlocking method like fingerprint or facial recognition, it’s still important to be familiar with it.

You’ll need to reset your Google Account password if you forget it or become locked out for some other reason when you try to keep accessing all of your data. You might also need to change lock screen passcode from time to time.

How to Change/Set up Lock Screen Password

Select Screen Lock Type under Settings > Lock Screen. From there, you may select from a variety of lock screen options:
