Setting pattern screen lock on Microsoft Lumia 532 - Microsoft Community

hi !! wonder know if on windows phone can install application allows me lock start screen patterns because know it's more safety password number . 
know if exist such application? tried find on appstore but there is only apps locker patterns not start screen.
please let me know how find type of application.

thanks in advance

if memory serves android offered password / pin & pattern

pattern being least secure due limited variations meant 3 wrong entries locked phone required user log gmail account 

despite  being 8 digits  too many wrong attempts "locks" phone increasing intervals each wrong entry before can try again

patterns quicker enter, pin number infinitely more secure
