Resource Owner Grant

The Password grant type is used by first-party clients to exchange a user's credentials for an access token. Since this involves the client asking the user for their password, it should not be used by third party clients. In this flow, the user's username and password are exchanged directly for an access token. The application acts on behalf of the user. Refer to OAuth 2.0 spec for more details.

Easy way

The easiest way to test Resource Owner Grant flow is to run through the Aidbox Sandbox UI (Auth -> Sandbox -> Resource Owner).

Configure Client

The first step is to configure Client for Resource Owner Grant with secret and password grant type:

PUT /Client/myapp
Accept: text/yaml
Content-Type: text/yaml

secret: verysecret
  - password

Client will act on behalf of the user, which means Access Policies should be configured for User, not for Client.

You can configure Client for JWT tokens, set token expiration and enable refresh token:




use access token in jwt format


int (seconds)

token expiration time from issued at



enable refresh_token



require client secret for token

Get Access Token

Next step is to collect username & password and exchange username, password, client id and secret (if required) for Access Token.

Using Authorization header {base64( + ':' + Client.secret)} or by JSON request with client_id and client_secret in body:

POST /auth/token
Authorization: Basic base64(, client.secret)
Content-Type: application/x-www-form-urlencoded


If provided credentials are correct, you will get a response with the access token, user information and refresh token (if enabled):

status: 200

 "expires_in": 3600,
 "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjgwODEiLCJzdWIiOiJ1c2VyIiwiaWF0IjoxNTU0NDczOTk3LCJqdGkiOiI0ZWUwZDY2MS0wZjEyLTRlZmItOTBiOS1jY2RmMzhlMDhkM2QiLCJhdWQiOiJodHRwOi8vcmVzb3VyY2Uuc2VydmVyLmNvbSIsImV4cCI6MTU1NDQ3NzU5N30.lCdwkqzFWOe4IcXPC1dIB8v7aoZdJ0fBoIKlzCRFBgv4YndSJxGoJOvIPq2rGMQl7KG8uxGU0jkUVlKxOtD8YA",

 "userinfo": {
  "email": "",
  "id": "user",
  "resourceType": "User",

Use Access Token

You can use the access token in Authorization header for Aidbox API calls:

GET /Patient
Authorization: Bearer ZjQyNGFhY2EtNTY2MS00NjVjLWEzYmEtMjIwYjFkNDI5Yjhi
curl -H 'Authorization: Bearer ZjQyNGFhY2EtNTY2MS00NjVjLWEzYmEtMjIwYjFkNDI5Yjhi' /Patient

Revoke Access Token (Close Session)

Aidbox creates a Session resource for each Access Token, which can be closed with a special endpoint DELETE /Session with the token in the Authorization header:

DELETE /Session
Authorization: Bearer ZjQyNGFhY2EtNTY2MS00NjVjLWEzYmEtMjIwYjFkNDI5Yjhi

Session is just a Resource and you can inspect and manipulate sessions by a standard Search & CRUD API. For example, to get all sessions: GET /Session
