Setting Up a Strong Lock Screen

One of the most fundamental steps to secure your personal and sensitive data in Android devices is by setting a strong screen lock. There are various options for screen locks which we can choose from Android settings inbuilt into our devices. Each type of screen lock method provides a different level of protection for our sensitive data. These lock screen methods include:

  • PIN
  • Pattern
  • Password
  • Biometric authentication

In the next subsection, we will discuss each lock screen method briefly to have insight into the lock screen feature.

Types of screen lock

  • PIN (Personal Identification Number): It consists of a combination of different numbers which can be any sequence, your birth date, phone number, etc. As it is the simplest form of screen lock, so it’s easy to guess or break it. So, while setting a PIN for your Android device, it must be a strong, unguessable, and unique number.
  • Pattern Lock: Pattern lock allows you to draw a specific pattern on a grid of dots to unlock your device. Similar to a PIN, it is important to create a complex pattern that cannot be replicated easily.
  • Password: It is a type of screen lock option that is a combination of uppercase, lowercase letters, numbers, and special characteristics. Among the first three types of screen lock methods, it is the strongest one and offers a high level of security. Just like PIN and Pattern, it must be complex and unguessable.
  • Biometric Lock: In biometric authentication, we either use fingerprint or facial recognition to unlock our device. Among screen lock methods, the biometric system is the most advanced and secure feature in our screen lock security option.
