Note: because some models of Android phones use different versions and/or layouts of the OS, these instructions will vary; these instructions were created using stock Android 4.2.2.
To enable a security lock (PIN, Password, or Pattern), you will need to do the following:
- Open the Settings app, and go to “Security” (under the Personal section)
- Select the type of screen security you wish to enable (default is “Slide“)
- You can choose from Slide, Face Unlock, Pattern, PIN, or Password
- Slide and Face Unlock are the least secure and are thus not recommended
- If you select “Pattern,” you will be prompted to select a size of pattern before drawing it.
- Once you select your method of security, enter the PIN/Password or draw your pattern and hit “Next”
- You will be asked to confirm the new pattern or PIN/Password before saving.
