Case Study: Jersey Mike's Subs achieves stronger security for 6 million loyalty accounts with Auth0

Why Jersey Mike's Trusts Auth0 With Their Most Loyal Customers’ Data

Jersey Mike’s, a fast-casual sub sandwich franchise with more than 2,000 locations, runs a MyMike’s loyalty program with over 6 million digital members. Consolidating customer accounts made security a top priority, and managing authentication and ongoing threat mitigation in-house became a resource-intensive burden for their engineering team.

Jersey Mike’s outsourced login and identity to Auth0 and enabled Breached Password Detection, which triggers automatic password resets and enforces password history to prevent reuse of compromised credentials. The change delivered rapid benefits (positive results within six months): fewer support calls, stronger account protection, and freed engineering capacity that was reallocated to customer-facing features and faster growth.
