Contribute to the identity Abstraction Layer, a vendor-agnostic library that decouples application teams from specific identity vendor SDKs
Collaborate with identity architects, backend API teams, and security engineers to ensure UI implementations align with authentication protocols and security requirements
Implement passkey and passwordless flows using FIDO2/WebAuthn standards
Build with forward compatibility in mind to support credential consolidation across multiple products and business lines over time
