Need a password reset flow in your mobile app without starting with a paid email platform? In Video 25 of AI Mobile Engineer 2026, we configure Supabase SMTP using a Google App Password, customize the password-reset email template, and build a complete email OTP verification flow in React Native Expo.

We use Cursor to create a clean forgot-password experience, an OTP screen with a 1-minute countdown, and a screen for setting a new password. Then we test the full process on a physical phone: request a reset, receive the email, verify the code, and update the password.

What we build in this video:
Gmail SMTP + Supabase Setup
* Create a 16-character Google App Password
* Configure the SMTP server in Supabase
* Customize the password-reset email template to send a token

Forgot Password & OTP Verification
* Build the forgot-password screen with Cursor
* Create an OTP verification screen with a 1-minute timer
* Verify the email code and let the user set a new password

Real Device Testing
* Run the app on a physical phone
* Request a password reset email
* Enter the OTP and complete the password reset flow
* AI-native development workflow
