After you send users an email message inviting them to connect their devices and a link to the security application, the users can install the security application on their devices.
To install the security application on a device, the user clicks the link in the email message. The download of the proper installation package starts immediately. When the download is complete, installation of the security application starts automatically.
The user can click the link in the message within 336 hours (two weeks) from the time the email message was sent. When this period expires, the user has to request a new email message containing an installation link.
