Decoupling Verification from the Cloud Monolith

Firebase Auth provides an excellent on-ramp for rapid prototyping within Google Cloud. However, mature engineering teams require infrastructure agility. Authepy delivers a completely agnostic, non-custodial Email OTP engine via native REST, preventing backend lock-in.

// Escaping The BaaS Trap

Owning Your Own Identity Layer

Firebase Auth is custodial by nature. It generates proprietary user IDs (UIDs), manages the underlying authentication database, and deeply integrates with Firestore rules. Migrating away from Firebase—or attempting to sync its identity state with a custom PostgreSQL architecture—creates massive technical debt.

Authepy was engineered by Valipod as a non-custodial utility. We do not store your user directories. You maintain a single source of truth in your own database (SQL, NoSQL, or Graph). Authepy simply provides the sub-3-second cryptographic delivery and verification pipeline needed to authorize a session.

// Code Initialization Overhead

Abstracting the Complexity

Compare the boilerplate required to initialize a Firebase client ecosystem versus Authepy's native server-driven REST model.

Firebase Client SDK
import { initializeApp } from "firebase/app";
import { getAuth, sendSignInLinkToEmail } from "firebase/auth";

const app = initializeApp({
  apiKey: "...",
  authDomain: "...",
  projectId: "..."
});
const auth = getAuth(app);
await sendSignInLinkToEmail(auth, email, actionCodeSettings);
Authepy Agnostic REST
// Executed purely on your backend. Zero client overhead.
await fetch('https://authepy.com/api/otp/request', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer ath_sec_live_...',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ email: req.body.email })
});

Reclaim Your Identity Layer

Stop binding your application's user directory to proprietary ecosystems. Switch to an infrastructure that verifies users flawlessly while leaving your system state entirely in your hands.
