Follow the below steps if you forgot lock screen password.


Enter a wrong lock screen pattern five times (shouldn’t be hard if
you don’t remember the correct one)
Select ‘Forgot Pattern’
Now you should be able to enter a backup PIN or your Google account
login.
Enter either your backup PIN or your Google login.
Your phone should now be unlocked.


You can also follow Device Manager by Android steps

Ensure that you had enabled Android Device Manager as a device administrator under security settings before trying this.


On a computer or other mobile phone, visit:
google.com/android/devicemanager
Sign in using your Google login details that you also used on your
locked phone.
In the ADM interface, select the device you need to unlock (if it
isn’t already selected).
Select ‘Lock’
In the appearing window, enter a temporary password. You don’t have
 to enter a recovery message. Now click ‘Lock’ again.
If it was successful, you should see a confirmation below the box
 with the buttons Ring, Lock and Erase.
On your phone you should now see a password field in which you
 should enter the temporary password. This should unlock your phone.
Now, before you go on with your life, go to your phone’s lock
 screen settings and disable the temporary password.


Disable your lock screen using custom recovery and “Pattern Password Disable”


Download the pattern password disable ZIP file on your computer and
 put it on an SD card.
Insert the SD card into your phone.
Reboot your phone into recovery.
Flash the ZIP file on your SD card.
Reboot.


Your phone should boot up without a locked screen. Should there be a password or gesture lock screen, don’t panic. Just type in a random password or gesture and your phone should unlock

That’s it!
