Can a user belong to multiple organizations?

A user has one identity but can belong to any number of organizations. This is important for real B2B products where the same person might be an admin of their own company and a guest in a partner's org.

• Each membership carries its own roles and permissions.

• The session and JWT include the active organization, which your backend uses as tenant context.

• The SDKs list a user's organizations and expose an org switcher so they can change the active one.

See the organizations guide.
