Biometric Authentication

This plugin enables biometric authentication for users in your WordPress application. Follow the steps below to configure and use the plugin effectively.

Step 1: Configure Biometric Authentication Settings

1. Navigate to the WordPress Admin Dashboard.

2. Go to Settings > Biometric Authentication.

1. Configure the following options:

• Enable Biometrics: Check this box to activate biometric authentication for users.

• Prompt on Resume: Enable a biometric prompt when the app is resumed.

• Prompt on Open: Enable a biometric prompt when the app is opened.

• Biometric Timeout (Minutes): Set the time delay (in minutes) after which biometric authentication will be required again.

1. Click Save Changes to apply the settings.

Step 2: Allow Users to Enable Biometric Authentication

1. Add the shortcode [wtn_biometric_settings] to a page (profile page) or post where users can manage their biometric preferences.

2. Logged-in users will see an option to enable or disable biometric authentication.

3. When enabled:

• Users will be prompted to authenticate via biometrics (e.g., fingerprint or face recognition).

• A secure token will be stored for subsequent authentication.

Step 3: Enable Biometric Login (optional)

1. Add the shortcode [wtn_biometric_login] to display a Login with Biometric button.

2. Unauthenticated users with biometric authentication enabled can log in using their biometrics.

3. The user will be redirected to their dashboard or the specified page if authentication is successful.

Note: The user will only be able to perform biometric login when their session or token has expired. Biometric login will not be available in the case of a forced logout.

Step 4: Automatic Biometric Prompts

• The plugin will automatically prompt for biometric authentication based on the admin settings:

  • On App Resume: If the app is inactive for the configured timeout.

  • On App Open: Every time the app is launched.

  • On Logout: If the user logs out, they must reauthenticate to access the app.
