Update user password

You can use the API ML to update a mainframe password. The Mainframe password change is possible through Gateway REST APIs and is supported by two authentication providers:

Note: This feature is also available in the API Catalog. For more information about how to update the mainframe password via API Catalog, see Change expired password via API Catalog.

Change password with SAF provider​

Update the user password using the SAF Authentication provider. To use this functionality, add the parameter newPassword on the login endpoint /gateway/api/v1/auth/login in a POST call to this endpoint.

The Gateway service returns a valid JWT with the response code 204 as a result of successful password change. The user is then authenticated and can consume APIs through the Gateway. A response code of 401 is thrown if it is not possible to change the password for any reason.

Use the following request body format in the POST REST call against the URL /gateway/api/v1/auth/login:

{
"username" : "<username>",
"password" : "<password>",
"newPassword" : "<newPassword>"
}

Note: It is a common practice to set a limit to the number of password changes permissible in the ESM. This value is set by the parameter MINCHANGE for PASSWORD. The password can be changed once. Subsequently, it is necessary to wait the specified time period before the password can be changed again.

Example:

MINCHANGE=120

where:

  • 120
    Specifies the number of days before the password can be reset

Change password with z/OSMF provider​

Update the user password using the z/OSMF Authentication provider. To use this functionality, add the parameter newPassword on the login endpoint /gateway/api/v1/auth/login in a POST call to this endpoint.

The Gateway service returns a valid JWT with the response code 204 as a result of successful password change. The user is then authenticated and can consume APIs through the Gateway. A response code of 401 is thrown if it is not possible to change the password.

Use the following request body format in the POST REST call against the URL /gateway/api/v1/auth/login:

{
"username" : "<username>",
"password" : "<password>",
"newPassword" : "<newPassword>"
}

Note: In order to use the password change functionality via z/OSMF, it is necessary to install the PTF for APAR PH34912.
