Case study: enterprise identity modernization
One WEX Auth0 SSO: one secure identity layer across 15+ products.
Leonardo Prado helped design and roll out Auth0-based SSO, MFA, onboarding, account migration, and backend identity services across more than 15 WEX products, reducing duplicated development cost and improving the customer login experience.
Problem
WEX customers needed a consistent and secure way to access multiple products. Without a shared identity layer, product teams risked duplicating login logic, MFA decisions, migration workflows, and onboarding behavior across separate applications.
Constraints
The identity layer needed to support multiple products, secure account migration, MFA adoption, backend service integration, and a rollout path that would not disrupt existing customers.
Approach
The work centered on Auth0-based SSO, MFA, onboarding, migration support, backend identity services, product integration patterns, and safe adoption across product teams.
Stack
Auth0, SSO, MFA, backend identity services, AWS, secure onboarding flows, account migration workflows, and product integration APIs.
Measured impact
The rollout supported 15+ WEX products, reduced development costs by about $3,200 per month per product, and migrated accounts without customer disruption.
Why it matters
Identity modernization is not just a login screen upgrade. Done well, it becomes platform infrastructure: fewer duplicated systems, clearer security controls, faster product onboarding, and a customer experience that feels unified across products.
