Many smartphone owners use pin all across the globe. It is much easier than typing the whole password. It can allow up to 16-digits which means you can make many different combinations to safeguard your data. 

However, the majority of the people choose the 4-digit pin as serves the purpose and also makes things much easier to operate and remember. 

Make sure to make such a combination that is complex and not predictable such as 1234 or 4444. But not that strong that ends up forgetting. 


It is the most secure way to lock your phone even to this date and time. A good password is highly unpredictable and you can use letters, both in lowercase and uppercase, numbers, etc., and make up a good combination. 

It ensures the safety of your phone and your personal information. The only downside to it is that typing in the long password every time you need to use your phone. 

It doesn’t pass as convenient as we tend to use our phone at least a hundred times a day.  So, it becomes a sort of an annoyance. There’s also the chance of mistyping long passwords leading to more delay.  


It is the most intuitive form of security lock which is both fun to use and ensures your safety. You can make up a simple pattern to even set up a complex one, depending upon your choice. This lock requires you draw a pattern on a grid of nine dots. 

You can make patterns either horizontally, vertically, or diagonally. What else? It is extremely easy to use as the pattern settles in the memory and you can make the swiping actions almost naturally every time you need to use your phone. 

Always make sure to hide while drawing the pattern as someone might be looking over your shoulder.  


It offers the lowest security. Therefore, it provides maximum convenience, ease, and speed. With just a swipe of a finger, you can unlock your phone. By setting this one, your phone is at high risk regarding safety.

The only issue is that some fingerprint sensors are not so much responsive. They might also not be placed in the best position. You also won’t be able to open your phone with a glove on. 

Facial Recognition:

You can unlock your phone just by putting it in front of your face. This lock system captures the structure of your face by using the camera and keeps it in its memory. This system, then, uses it for verification the next time you try to open your phone. 

Notably, it becomes a nuisance when it fails to recognize the face due to poor lighting or when you are wearing glasses. It may also detect any other look-alike person due to which it can pose as a threat. 

Smart Lock:
