Case Study: Arduino achieves 3x higher user conversion by simplifying logins with Auth0

How Arduino Increased User Conversion 3x by Simplifying Logins

Arduino, the open-source hardware, software, and content platform with about 2 million active users and 35 million annual website visitors, was held back by an in-house identity and access management system that cost roughly $100,000 a year to maintain and posed security and compliance challenges. Arduino needed a scalable, GDPR-compliant IAM solution that could serve a diverse user base from schoolchildren to professional engineers while reducing operational overhead.

By adopting Auth0’s IDaaS with Single Sign-On and social logins (Google, GitHub), Arduino simplified and sped up authentication—logins now take under a second (3x faster)—which tripled user conversion and drove ~20% month-over-month growth (vs. an expected 7%). The change also accelerated development (IoT and Android logins implemented in 2.5 days), enabled 2FA adoption by 20% of professionals, supported GDPR-compliant ephemeral accounts for minors, and offloaded security and support responsibilities.
