+## How can I enable password reset
+There is no setting for password resets. It is enabled when a [mail service]({{< relref "doc/usage/email-setup.en-us.md" >}}) is configured, and disabled otherwise.
+
+## How can a user's password be changed
+- As an **admin**, you can change any user's password (and optionally force them to change it on next login)...
+  - By navigating to your `Site Administration -> User Accounts` page and editing a user.  
+  - By using the [admin CLI commands]({{< relref "doc/usage/command-line.en-us.md#admin" >}}).  
+  Keep in mind most commands will also need a [global flag]({{< relref "doc/usage/command-line.en-us.md#global-options" >}}) to point the CLI at the correct configuration.
+- As a **user** you can change it... 
+  - In your account `Settings -> Account` page (this method **requires** you to know your current password).
+  - By using the `Forgot Password` link.  
+   If the `Forgot Password/Account Recovery` page is disabled, please contact your administrator to configure a [mail service]({{< relref "doc/usage/email-setup.en-us.md" >}}).
