Email Magic Link

Magic Link Authentication

What is Magic Link?

Magic Link is a secure and user-friendly authentication method that simplifies the login process by sending users a unique link via email. Instead of relying on traditional passwords, Magic Link allows users to access their accounts by clicking on the provided link, eliminating the need to remember and manage passwords.

Benefits of Magic Link Authentication

  • Simplicity: Users can log in with a single click, reducing friction and enhancing the user experience.

  • Security: Magic Links are time-sensitive and unique to each login attempt, adding an extra layer of security to the authentication process.

  • No Password Hassles: Eliminates the need for users to remember and manage passwords, reducing the likelihood of forgotten passwords and password-related issues.
