Why This Matters for North East India Developers
In the rapidly evolving world of app development, ensuring a secure and user-friendly experience is paramount. One critical aspect of this is the implementation of a robust "Forgot Password" flow. This article demonstrates how to build an OTP-based reset flow using the popular Better Auth and Nodemailer tools, a method particularly relevant for developers in North East India who are building production apps.
Preparing Your Backend for the OTP Flow
If you've followed our previous guide on setting up Better Auth with Nodemailer, your backend is already primed for this task. The emailOTP plugin we installed earlier handles the forget-password type automatically.
Ensuring Dynamic Subject Lines
To ensure your email.ts template handles password resets appropriately, ensure it dynamically updates the subject line or uses a generic enough subject for password resets.
Building the Client-side Implementation
We'll focus on the key functions and the core logic of the UI, rather than dumping lines of UI code. The client-side implementation involves handling two distinct stages: requesting the OTP and resetting the password.
The Logic Hooks
Using the authClient, we define two core functions: sendResetOtp and resetPassword. These functions handle the logic for requesting the OTP and validating it, respectively.
The UI Implementation
We'll compose the UI to handle the Request Form (Stage 1) and the Reset Form (Stage 2) distinctly. The Request Form asks for the user's email, while the Reset Form requires the OTP, new password, and confirmation of the new password.
Magic Link vs. OTP: Which One to Choose?
Both Magic Links and OTP approaches have their pros and cons. The OTP approach, as demonstrated in this guide, offers a seamless context and is mobile-friendly. However, it requires manual input and is prone to typos. On the other hand, Magic Links provide zero friction but force users to open a new browser window/tab and may be intercepted by aggressive email scanners.
Keeping Users Engaged within Your App Ecosystem
By using the emailOTP plugin in Better Auth, we've created a password reset flow that keeps users engaged within our application. This small UX detail can lead to higher conversion and retention, making it a valuable consideration for developers in North East India.
