Updating 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:

• Changing password with SAF provider
• Changing password with z/OSMF provider

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.

Changing 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

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

Changing 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>"
}
