Locking your phone is not all about keeping it away from making self-dialed calls when inside your pocket. Phones have a lot of confidential information and need to be kept privy to other people. Leaving it open with no password can cost you many losses. 

People use phones to store vital information like bank pins, security details, and academic information. So, it is crucial to maximize the lock options on your phone and avoid uncertainties. One of the significant advantages is that when you misplace your phone or get stolen, no one can unlock it. 

Different phones have various types of phone locks, and one phone model can have many lock options. Here are ways which you can lock your iPhone and Android phones within seconds.

Ways to Lock an Android Phone

Password Protected

Using a password to secure your Android phone is among the more robust methods. Passwords are hard to guess, and once you set it, you are sure that no one else can access your phone. However, always pick a password that is hard to crack by another person but easy for you to remember. 

There are various categories under the password option, which include pin, pattern, and swipe. You can choose any to lock your phone. Even if you use the trusted sensor-based methods like Bluetooth and NFC, you will still end up with the password option three to four times a day. Here are the steps to lock your phone using a password. 

Open system settings.

Go to security settings. Depending on the phone model under the security tab, click on “My device” or “Personal Header” If you don’t trace it, you will need to check out for the lock screen option.

For instance:

  • The swipe lock option allows you to unlock your screen by swiping it once. It is, however, not a secure form of locking your phone.
  • Pattern: You can lock your screen with a unique design by following a grid connection of dots. Patterns can be a bit confusing, so you will need to master it for easy unlocking. 
  • Pin: You have the option to choose A4 to 17 digit PIN. Anyone can guess a PIN, so you need to create a mix up of numbers for complexity. 
  • Password: You can create a password with digits, letters, symbols, or words to lock your phone. It is likely the best option to use. 


Just as the government would ask you for fingerprints, you can also lock your Android phone with it. Someone cannot crack this type of phone lock, which requires a lot of intelligence and effort. Securing your phone with a password can be a more reliable and safer method, but it can’t beat fingerprints. Some phones have fingerprints sensors, too, creating even a higher layer of protection. Here is the procedure to set up on your phone. 

  • Go to settings and tap the security option, get down to the lock screen tab and click it.
  • Click on the screen lock type and chose fingerprints.
  • Create a fingerprint – You don’t have a limitation on what kind of finger to use. Follow through the prompts and let the phone get your finger as you lift and move on the screen. It will be automatically added and authorized on your device.
