### Extract the UDID

The method you employ to identify and acquire the UDID is based on the following factors:

- If you have iTunes installed on a PC or MAC, extract the UDID using [iTunes](/capture-mobile/docs/prerequisites-for-installing-on-ios#using-itunes).
- If you have an MDM in your organization, request your IT staff for the UDID.
- If you do not have iTunes or MDM, you can extract the UDID using [profile installation](/capture-mobile/docs/prerequisites-for-installing-on-ios#using-profile-installation). If your iPhone does not support profile installation, extract the UDID using a [USB cable](/capture-mobile/docs/prerequisites-for-installing-on-ios#using-usb-cable-on-windows-or-mac).

#### Using Profile Installation

To extract the UDID using a profile installation:

1. On your iPhone, open the Safari browser and navigate to [https://udid.tech/](https://udid.tech/) and download the profile.
