Amazon Cognito and Firebase Auth — 2014-era managed identity peers to Auth0

Summary

Claim: Amazon Cognito (2014) and Firebase Auth are peer managed-identity services to Auth0. Firebase Auth's exact launch date is not separately confirmed beyond Firebase's acquisition by Google in 2014.

Source: Multi-source.

Confidence: Verified for Cognito 2014; Firebase Auth exact date needs-verification.

Caveat: Firebase Auth exact launch date not separately confirmed.

Why this matters for Candid: Establishes that managed-identity wasn't a single-vendor accident. By 2014 the major clouds had each delivered an auth service — the bespoke "roll your own" path ([[pre-auth0-roll-your-own-password-hashing]]) was already the losing choice.
