Email + OTP Authentication

The future of authentication is passwordless. Email + OTP provides a seamless, secure, and user-friendly way to verify your users.

Why Email + OTP is the Best Choice

Superior User Experience

No more password creation, memorization, or reset flows. Users simply enter their email and receive a one-time code. It's fast, intuitive, and frustration-free.

Enhanced Security

Eliminate password-related vulnerabilities. Each login requires access to the user's email, and OTP codes are single-use and time-limited. No more weak passwords or credential stuffing attacks.

Linear Authentication Flow

A straightforward, step-by-step process that guides users from start to finish. No complex forms or confusing password requirements. Just email → code → access.
