A PHP library implementing simple Single Sign-On (SSO), allowing users to log in once at a central server and be automatically authenticated across multiple affiliate websites that need not share a top-level domain. It differs from OAuth by sharing a full session between brokers rather than just exchanging profile info.

Use cases

• implement single sign-on across multiple php websites
• share login sessions between sites on different domains
• avoid requiring users to log in again on each affiliate site
• centralize user credentials on one authentication server
• log out users across all connected sites at once
• replace oauth-based login with true session sharing

When to choose

• you control a central auth server and multiple php broker sites
• you want simple, lightweight SSO without OAuth complexity
• affiliate sites are on different top-level domains but should share sessions

When to avoid

• you need a standards-based protocol like SAML, OIDC, or OAuth2
• your stack is not PHP
• you need federated identity with external identity providers
