link: Passwordless Authentication

Email Link Authentication

Overview

Email Link Authentication is a Passwordless Authentication method where users log in by clicking a one-time link sent to their email address. This method enhances security by eliminating the need for passwords and simplifying the user login process.

How It Works

1. User Initiates Login: The user enters their email address on the login page.
2. Send Authentication Link: The server generates a one-time link and sends it to the user’s email.
3. User Clicks Link: The user clicks the link in their email, which redirects them to the application.
4. Access Granted: The server verifies the link and grants the user access.

Pros and Cons

Pros

• Simple User Experience: No need to remember or enter passwords.
• Enhanced Security: Reduces the risk of password-related attacks.
• Easy Implementation: Straightforward to set up and integrate.

Cons

• Email Dependency: Requires users to have access to their email.
• Potential Delays: Email delivery can sometimes be slow or unreliable.
• Link Expiry: One-time links need to be carefully managed to ensure they expire after a short period for security reasons.

Use Cases

• Account Login: Simplifies the login process for applications and websites.
• Password Recovery: Can be used as a method for recovering access to accounts.
