Android Security

Password vs. PIN vs. Fingerprint: 

Password

• Pros: A strong password is very secure.
• Cons: Not convenient to type many times each day.
• When to use it: When you need the highest level of security.

PIN Code

• Pros: Easier to enter than a password.
• Cons: A strong PIN code can be difficult to remember.
• When to use it: As a backup to a bio-metric security option.

A PIN code is a simple alternative to a password. Android allows PINs of up to 16 digits, which equates to 10 quadrillion combinations. While a 16-digit PIN is extremely secure, it’s tough to remember.

Pattern Lock

• Pros: Simple and intuitive to use.
• Cons: Many people choose simple, predictable patterns.
• When to use it: If you don’t have a fingerprint scanner and dislike PINs.

The pattern lock requires you to draw a pattern on a grid of nine dots. You need to join between four and all nine horizontally, vertically, or diagonally. It’s easy to use because swiping gestures feel completely natural, and once you’ve built up muscle memory you can do it rapidly.

Fingerprint Sensor

• Pros: Fast and quite secure.
• Cons: Sensors aren’t always positioned in the right spot.
• When to use it: The default for most users.
