B2C SLAS Authentication Patterns

Advanced authentication patterns for SLAS (Shopper Login and API Access Service) beyond basic login. These patterns enable passwordless authentication, hybrid storefront support, and system-to-system integration.

Scope & grounding

This skill covers SLAS authentication patterns including passwordless login (email OTP, SMS, passkeys), session bridging, hybrid authentication (B2C 25.3+), token management, TSOB, and JWT validation with framework-specific examples for PWA Kit, Storefront Next, and SFRA. Code examples are illustrative of typical flows. Before answering version-specific questions, framework-specific implementations, or providing code the user will run in production, confirm current API contracts, parameters, rate limits, and version requirements against the official documentation via b2c docs search and b2c docs read. The canonical docs are the authoritative source for B2C platform specifics, API shapes, and configuration requirements.
