Learn how to apply a new or more secure screen lock to an Android. Also, find out how to change the existing screen lock, add a secure PIN or password lock, remove the screen lock by replacing it with something less secure, and locate fancy screen locks for your Android.
- [Instructor] For extra security, I recommend that you apply a screen lock to your Android device. Several types of screen lock are available, from none or no screen lock, to a very secure password screen lock. Your device might also have fancy screen locks, like a fingerprint unlock, face unlock, or a signature unlock. To find the screen locks, open the Settings app. In older versions of the Android operating system, look for the Security item and then choose Screen Lock. This device runs Android 8.1, so I choose Security & Location and then Screen Lock.
On some Samsung devices, choose Lock Screen and Security and then Screen Lock Type. If a screen lock is already applied, you'll be required to work that lock before you see the lock screen options. This is the pattern unlock. Here, you see the basic screen locks. None, which is no screen lock. Swipe, the standard screen lock. Pattern, which you just saw. PIN and Password, which are the most secure screen locks. These locks appear when you first start or unlock the device.
You work the lock, then you can use your phone or tablet. Now, unlocking a phone isn't necessary for an incoming phone call. Just answer the phone. Though, if you want to use other features while you're on the call, you must work the screen lock to continue. To set or change a lock, choose it from the list. I'll choose Pattern to reset the existing pattern lock. The pattern is the most popular screen lock. Now, if prompted, confirm that you want the screen lock to appear at start-up. Tap the Yes button.
Draw a pattern covering at least four dots. You cannot cover the same dot twice. Tap Next or Continue and trace the same pattern again. Tap Confirm. Now, you may be asked to type a pin or password as a backup. Do so if prompted. Now I'm going to lock the device. And to unlock it, I'll trace the pattern.
The two most secure screen locks are the pin and password. They're required for devices that access secure email servers or which have encrypted data or host multiple accounts. The pin and password locks are similar. The pin is composed of numbers and the password is composed of numbers, letters, and symbols. To set either one, choose Pin or Password from the Choose Screen Lock screen in the Settings app. I must, again, use the pattern to unlock the device.
This time, I'm going to choose PIN and confirm for secure start-up. Type at least four numbers. Next, same four numbers, OK. Now I'll lock the device. And unlock. Type the pin to continue. To remove a screen lock, you replace it with the swipe or none locks. Though, if your device is encrypted, you won't be able to remove the secure screen lock.
And if your device offers specialty locks, you'll also find them on the Security and Location screen in the Settings app. On Samsung devices, choose the Lock Screen and Security item in the Settings app. You'll find options for face recognition, fingerprint scanner, iris scanner, and even the signature lock, depending on the capabilities of the device you're using.
