Slide - The slide provides no protection, but lets you get to the Home screen quickly, or open the Camera and take pictures immediately.
Face Unlock - Lets you unlock your Sero 7 by using facial recognition. This is the least secure lock option.
Tip: After you set Face Unlock up, look under Settings > Personal > Security > Screen Security for two additional settings: Improve face matching and Liveness check. Use these to make Face Unlock more reliable and secure.
Pattern - Lets you draw a simple pattern with your finger on the screen to unlock your Sero 7. This is slightly more secure than Face Unlock.
PIN - Requires four or more numbers. Longer PINs tend to be more secure to unlock.
Password - Requires four or more letters or numbers. This is the most secure option, as long as you create a strong password.
Tips: For best security, specify a password that is
•A least 8 characters long.
•Contains a mixture of numbers, letters, and special symbols.
•Doesn’t contain any recognizable words or phrases.

Downloading files in Chrome, Gmail, and other apps.
Creating files (for example, by taking pictures).
