Push Notification Authentication

Overview

Push Notification Authentication is a Passwordless Authentication method that uses push notifications sent to a user’s registered mobile device to verify their identity. This method enhances security by leveraging the user’s smartphone for authentication, ensuring that only the device owner can approve login requests.

How Push Notification Authentication Works

1. User Initiates Login: The user attempts to log in to an application or service.
2. Push Notification Sent: The authentication server sends a push notification to the user’s registered mobile device.
3. User Approves Request: The user receives the notification and approves or denies the login request.
4. Authentication Verified: If the user approves the request, the authentication server verifies the approval and grants access.

Pros/Cons

Pros

• High Security: Requires possession of the registered mobile device, reducing the risk of unauthorized access.
• User-Friendly: Simplifies the login process by eliminating the need for passwords.
• Real-Time Verification: Provides immediate authentication, enhancing user experience.

Cons

• Dependency on Mobile Device: Requires users to have their registered mobile device available.
• Internet Connection Required: Both the server and the mobile device need an active internet connection for the push notification to be received.
• Potential for Notification Overload: Users may become desensitized to push notifications if they receive too many, increasing the risk of ignoring important authentication requests.
