Credentials change

Authentications credential change works in two steps:
  • a credential change request action
  • an actual credential change using a secret hash

Only use case currently supported is password change.

After a request action an email is sent to requesting user containing a URL with a secret hash to actually perform the change.

POST /auth/change

Request a credential change.

Form Parameters:
 
  • contact – Email of user requesting credendials change.
  • change_url – Change URL that will be sent via email.
Status Codes:

Example request: Since this is not a JSON API request you MUST use Content-Type: application/json

POST /auth/change HTTP/1.1
Content-Type: application/json

{
    "contact": "{my email}",
    "change_url": "{change url}"
}

A change_url is required in order to create the URL that will be sent to the user in this form:

{change_url}?uuid={uuid}

Where {uuid} is a system generated hash that will expire after 24h.

In your change_url page you will have to read the uuid query parameter and proceed to actual change performing the following request.

PATCH /auth/change

Perform a credential (password) change.

Form Parameters:
 
  • uuid – Secret UUID sent via email in change_url.
  • password – New user password.
  • login – Optional boolean parameter, if true a login is also performed.
Status Codes:

Example request: Since this is not a JSON API request you MUST use Content-Type: application/json

PATCH /auth/change HTTP/1.1
Content-Type: application/json

{
    "uuid": "{uuid}",
    "password": "{new password}",
    "login": true
}

Response will contain user data as in previous Who Am I? request.

If "login" is true a login is also performed and JWT access token and refresh token tokens are returned in "meta" section for immediate use. This key is optional, if missing "login": false is assumed.
