Therefore Backup PINs are so important which can help you in such situations where you forget the screen lock password.

Here is how to unlock LG phone without password using the Backup PIN:

On a locked device, let us consider a device which is pattern locked and you don’t remember the password, try entering the wrong pattern 5 times. After you have entered 5 wrong patterns, it will ask to enter after 30 seconds. At the bottom of the screen, there would be an option saying “Forgot Pattern” as shown in the picture below.

Step 2:

Now that you have tapped on “Forgot pattern” you would find the field where you can enter the Backup PIN on the next page. You would find the below screen where you can enter the Backup PIN.

If you don’t remember the phone lock screen password or pattern lock of LG G2/G3/G4, you can easily unlock the phone using the Google account. Android phones are configured with Google account and since they are, the phone can be unlocked even if you have forgotten the password or pattern lock by using the Google account details the phone is configured with. This is a very simple process and the details can be fed on the lock screen itself to bypass it and unlock the device. Here is how to unlock LG phone without code using the Google account details.

Step 1:

First of all, if you have set a password or pattern lock on the LG device and now don’t remember the password or code to unlock, the Backup PIN can help. Let us consider that you have set pattern lock and don’t remember the pattern now to unlock. So, on the lock screen, make 5 wrong pattern unlock attempts and then the phone will ask you to try attempting after 30 seconds.

Select “Forgot pattern” from the above screen of the phone.

Now, after you have tapped on “Forgot pattern”, on the next screen, you will find fields to enter the Google account details as well as the Backup PIN. Enter the Google account details here. The Google login details have to be same as the Google account details the LG phone is configured with.

Step 3:

After you have signed in with the same Google login details and land on the Android Device Manager interface, you will find all the devices configured with the same Google account listed. So, among the listed devices on the interface, select the particular device which has to be unlocked, if you don’t find the device automatically selected. If you have only one device configured with this Google account, only one device name would show up on the interface already selected.

Step 4:

Now, click on “Lock” from the three options shown up on the screen as can be seen above. The following screen will show up when you click on “Lock” option present at the top left of the screen.

Now, after you have entered the temporary password and confirmed, click on “Lock” option again. This will reset the phone password with the temporary password you just entered.

Step 5:

After the password is reset, you will find a confirmation. Moving on to the locked phone now, you should find a password field on the phone where you can enter the new temporary password. This will unlock your LG G2/G3/G4 device.
