Once the App is installed and activated, follow these steps to use it effectively :

### Client Registration & Login

Client can register their Passkey Login credentials from their profile page.

- They can also enable or disable Passkey Login at any time from the same page.
- On the login page, if Passkey Login is enabled for the customer (both personally and by staff), a Login with Passkey button will appear.
- Clicking the button will trigger the Passkey Login authentication prompt (Face ID, Fingerprint, PIN, etc.).

### Staff Registration & Login

- Staff can also register their Passkey Login credentials from their profile page.
- They can enable or disable their Passkey Login option just like clients.
- On the admin login page, if Passkey Login is enabled for the staff (both personally and globally), a Login with Passkey button will be displayed.
- Clicking this button invokes the Passkey Login prompt for secure authentication.

### Authentication Flow

- Passkey Login bypasses password entry if biometric/PIN verification is successful.
- If authentication fails or the user has no registered credentials, fallback to standard login is required.
- Authentication is based on device-stored credentials linked securely to the user account.

### Credential Management

User can set up multiple devices for easy login on multiple devices.

### Admin Settings

Admin can globally enable or disable Passkey Login for clients and/or other staff users.

If disabled, all users will be forced to use traditional login methods.

Can add app name which will be displayed on passkey login popup.
