Case Study: Acast eliminates identity maintenance and boosts user conversion with Auth0

Acast Eliminates Identity Maintenance Costs With Auth0

Acast is a global podcast platform that hosts tens of thousands of shows and reaches hundreds of millions of listeners monthly. Rapid growth exposed limits in their in‑house authentication — maintaining servers, securing user data, and scaling login flows was costly and diverted engineering resources from core product work.

Acast integrated Auth0, quickly migrated its user database, and added social logins and MFA. The change boosted user conversion, eliminated ongoing identity maintenance (freeing the equivalent of about eight people), enabled expansion into indie and smaller customers, and delivered stronger security and compliance as the company scales.
