SuperAuth is the universal SSO platform for the modern web. Let your users log in once and access every connected app — seamlessly, securely, and with style.
Our patent-pending DeepLink system lets external apps authenticate users with a single redirect — no OAuth headaches, no token management nightmares.
Bcrypt-12 password hashing, TOTP 2FA with QR codes, session rotation, rate limiting, and helmet.js CSP headers built in by default.
Google, GitHub, Facebook, Twitter, Instagram and Microsoft ready to go. Users sign up once and link all their accounts in the settings panel.
Real-time signup tracking, clickthrough rates, login trends, and daily active user counts — all in a beautiful dashboard with animated charts.
Built-in age verification prevents under-13 signups. Birth year analytics help you understand your audience without storing exact birthdays.
Time-based OTP with QR code scanning for any authenticator app. Backup codes stored. Disable with password confirmation. Zero friction for legit users.
