Case Study: WeTransfer achieves unified, secure identity and higher freemium conversion with Auth0

WeTransfer Unifies Identity Across Its Offerings With Auth0

WeTransfer, a creative-focused platform used by 70 million people to send around 2 billion files each month, faced fragmented user identity across its growing suite of products. Each product managed logins separately, making secure features, marketing communication, and cross-product adoption difficult — and building a centralized system in-house would have diverted engineering resources from core product work.

WeTransfer chose Auth0 and, with professional services support, rolled out centralized authentication and social logins (Google, Apple, Slack) across its three products in about three to four months. User identities are now merged into a single database with unified security controls (MFA, brute-force protection), which boosted freemium account conversion, simplified security management, and enabled product bundling and deeper cross‑product integration.
