In Safari on the iPhone, tap the button above and Allow the configuration profile to download.
Open Settings → tap Profile Downloaded at the top → tap Install.
Safari reopens this page with your UDID on screen. Copy it, send it to your developer, delete the profile.
This uses Apple's official “Profile Service” mechanism. The profile reads only the UDID, model and iOS version, shows them to you in your browser, and nothing is stored on our servers. Remove the profile immediately after — it has no ongoing access to anything.
Developers need your device's UDID to register it for ad-hoc test builds — Apple only lets an ad-hoc app install on registered devices. Without it, installs fail with “Unable to Install”.
Once your developer has your UDID and re-signs the build, they can send it to you as a one-tap install link through IPALinked — free, up to 500MB, no signup.
Mac: connect the device, open Finder, select it, click the subtitle line until UDID shows, right-click → Copy. Windows: iTunes → device icon → Summary → click Serial Number until UDID appears.
