Forgotten passwords frustrate users and increase support tickets. A new tutorial demonstrates how to build a secure password backup system using magic links in Node.js, eliminating the need for users to remember old credentials. The approach relies on the `auth-verify` library alongside `express` to handle the authentication flow.

Developers start by installing dependencies and initializing `AuthVerify` in `server.js`. Configuration involves setting a secret key, defining an expiration time for links, and choosing a token storage method, such as memory or Redis. The tutorial also covers configuring an email sender, typically Gmail, to deliver the links.

Three core endpoints drive the system. A POST route sends the magic link to the user's email. A GET route verifies the token when the user clicks the link, presenting a password reset form if successful.

Finally, a POST route accepts the new password. This setup offers a seamless, user-friendly alternative to traditional email resets, leveraging `auth-verify` to handle the complex security logic.
