  title: Addresses Introduction Account Addresses Authentication Realms API
  description: 'The Addresses API allows you to organize account addresses. Addresses are a sub-resource of `account` resources, an account can have multiple addresses, such as home, work, and neighbour.


    You can use an account address with either [client_credentials access token](/docs/api/authentication/create-an-access-token) or a combination of [implicit access token](/docs/api/authentication/create-an-access-token) and [Account Management authentication](/docs/api/accounts/post-v-2-account-members-tokens) token.

  description: "An authentication realm is a container that consists of the following:\n\n  - Users -  Represented by [User Authentication Info](/docs/api/single-sign-on/user-authentication-infos) objects\n  - Authentication profiles - Ways for the users to authenticate, such as one or more [OpenID Connect Profiles](/docs/api/single-sign-on/oidc-profiles) or [Password Profiles](/docs/api/single-sign-on/password-profiles)\n  - Mappings between users and authentication profiles - [User Authentication OpenID Connect Profile Info](/docs/api/single-sign-on/user-authentication-oidc-profile-infos) or [User Authentication Password Profile Infos](/docs/api/single-sign-on/user-authentication-password-profile-infos)\n\nHere's a domain diagram showing these relationships\n![authentication realm](/assets/authentication-realm-domain.png)\n\nComposable Commerce comes with three per-store pre-set realms:\n  - Buyer Organization. For customers: users who buy products from your store.\n  - Merchant Organization. For administrators: users who log in to Commerce Manager to modify the store’s settings or catalog.\n  - Account Management Realm. For account members: users who buy products from your store on behalf of accounts. Password profiles are only available for account management realm.\n"

In Single Sign On (SSO) each user in the Identity Provider (IdP) has a unique identifier, but different IdPs might differ in whether distinct users can share the same email address. For the `allowed` setting, when a user with a new unique identifier signs in through SSO for the first time, the system creates a new user. However, for the `api_only` setting, the system assigns the new unique identifier to the existing user in the system, in this case both the old and new unique identifier from the IdP points to the same user in Commerce. The `api_only` setting is recommended only when all configured identity providers treat e-mail address as a unique identifier for the user, otherwise a user might get access to another user’s account and data. Thus the `api_only` value can simplify administration of users.
          enum:
