Change a User’s Password

Changed in version 2.6.

Overview

Strong passwords help prevent unauthorized access, and all users should have strong passwords. You can use the openssl program to generate unique strings for use in passwords, as in the following command:

openssl rand -base64 48

Prerequisites

You must have the changeAnyPassword action on a database to modify the password of any user on that database.

To change your own password, you must have the changeOwnPassword action on your database. See Change Your Password and Custom Data.
