Welcome to the PasscodeView wiki!

• Secure authentication is the key factor in many application (e.g. financial applications). Many application uses PIN-based authentication.

• But Android System doesn't provide any easy to set the view for PIN-based authentication which can tightly integrate and take advantage of fingerprint API introduced in newer versions of android. This limitation led me to work on this project.

• With the use ofPasscodeView you can easily integrate PIN & Fingerprint based authentication in your application.

This library provides an easy and secure PIN and Pattern based authentication view, which

• It provides access to built-in fingerprint-based authentication if the device supports fingerprint hardware. This handles all the complexities of integrating the fingerprint API with your application.
• It provides error feedback when PIN or pattern entered is wrong.
• Extremely lightweight.
• Supports dynamic PIN sizes for PIN-based authentication. That means you don't have to provide a number of PIN digits at runtime.
• Supports custom authentication logic for PIN and Pattern. That means you can send the PIN or pattern to the server for authentication too.
• It is highly customizable. So that you can match it with your application them. It provides you control over,
  • color and shape of each key. 👉Guide
  • localized name of each key in pin keyboard. 👉Guide
  • size of every single key.
  • color and shape of indicators to display a number of digits in the PIN.👉Guide
  • color and shape of pattern indicators.
  • tactile feedback for key press and authentication success/failure events.
