PasscodeView is an Android Library to easily and securely authenticate the user with the PIN code or using the fingerprint scanner.
-
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 ๏ฟฝuse of PasscodeView you can easily integrate PIN & Fingerprint based authentication in your application.
This library provide easy and secure PIN authentication view, which
- provides access to built-in fingerprint-based authentication. This handles all the complexities of integrating the fingerprint API with your application.
- provide error feedback when PIN entered is wrong.
- is highly customizable. So that you can match it with your application them. It provides you control over,
Authentication using PIN/Fingerprint
Success | Fail | Fingerprint Success | Fingerprint Fail |
---|---|---|---|
Localized Texts
English | Hindi |
---|---|
Different Key Shape
Rectangle | Circle | Square |
---|---|---|

- There are three built in key shapes. You can also generate your own key by extending
Key
class.- Round key
- Rectangle key
- Square key
- Here is the example for the round keys.
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //.... //... PinView pinView = (PinView) findViewById(R.id.pin_view); pinView.setCorrectPin(new int[]{1, 2, 3, 4}); //Build the desired key shape and pass the theme parameters. //REQUIRED pinView.setKey(new RoundKey.Builder(pinView) .setKeyPadding(R.dimen.key_padding) .setKeyStrokeColorResource(R.color.colorAccent) .setKeyStrokeWidth(R.dimen.key_stroke_width) .setKeyTextColorResource(R.color.colorAccent) .setKeyTextSize(R.dimen.key_text_size) .build()); //... }

- Round indicator
- Dot indicator
- Here is the example for the round indicator. You can learn more about other indicators from here.

- Set the texts to display on different keys. This is optional step. If you don't set the key names, by default
PINView
will display English locale digits. - If you want to learn more about key name localization visit here.
