← WordPress SSO and Identity: A Complete Guide
How do you give one login access to several apps?
Make WordPress the identity provider: users authenticate once on the WordPress member portal, and every connected application trusts that authentication instead of asking for its own separate login. WordPress becomes the single source of truth for who’s logged in; every other app is a service provider that defers to it.
WordPress as the identity provider
This flips the usual SSO direction. Instead of WordPress being the application that trusts an external IdP (Okta, Azure AD, an OAuth provider), WordPress becomes the IdP itself, issuing the tokens or assertions that other applications rely on. That means WordPress needs to own identity fully: authenticating users, issuing credentials other systems accept, and giving administrators one place to manage who can access what, instead of permissions scattered across every connected tool’s own settings.
Connecting the service-provider apps
Each connected application needs to trust WordPress’s identity instead of maintaining its own login, which usually means integrating against whatever protocol WordPress exposes as the IdP (a custom token scheme, OAuth/OIDC, or similar). New applications should be able to join the system through configuration, not a new round of custom development every time the platform adds a tool.
Session and token management across apps
Once one login unlocks several applications, the security stakes on that single session go up: WordPress’s authentication is now the key to everything connected, not just to WordPress itself. Access needs to be revocable per user and per application, not all-or-nothing, so an administrator can pull one person’s access to one tool without touching everything else they can reach. Tokens and sessions need real expiration and validation, the same discipline any SSO implementation needs, just applied across more surface area than a single-app login.
Real example
84EM built a single sign-on system for an AI platform where members authenticate once on the WordPress member portal and access any connected application with one click. Administrators assign specific applications to individual users through a WordPress interface, with default access assignments for new members, and new applications join the system through configuration rather than custom development for every addition.
See WordPress OAuth and OpenID Connect SSO for the protocol layer this pattern is usually built on.
