Browser guidance

UDID browser help for iPhone and iPad

Safari works, and Chrome or another full iPhone browser can usually trigger the profile prompt too. The common failure case is opening the page inside another app instead of a real browser.

Use the target phone or tablet

Open in Safari or Chrome

Finish the profile flow there

Fastest fix

Reopen the same page in a full browser

1Open the same URL in Safari or Chrome on the target iPhone or iPad.

2Tap Download Profile and allow the configuration-profile prompt.

3Finish the install step and let BetaDrop return to the result page.

If iPhone asked you to wait an hour

That is Apple's Stolen Device Protection, and it is working as designed. When it is on and the iPhone is somewhere it does not recognise as a familiar location, some actions become a Security Delay: Face ID or Touch ID, a one-hour wait, then a second Face ID or Touch ID. Apple's list of delayed actions names enrolling in Mobile Device Management, and BetaDrop's UDID profile is reported to be treated the same way by affected devices. Depending on where the install was started you may see a Start Security Delay prompt, or Safari may simply report that it could not install the profile.

Apple introduced the feature in iOS 17.3 and says it might be turned on by default, so plenty of testers now meet it without ever having switched it on. Nothing is wrong with your device or with BetaDrop, and you do not have to start the check over.

1If iPhone offered a Start Security Delay button, tap it — the hour does not begin counting until you do.

2Keep your BetaDrop result link. The request stays open for 90 minutes, which is deliberately longer than Apple's hour.

3Wait for the iPhone notification saying the security delay has ended, then confirm with Face ID or Touch ID.

4Run the profile install again from your result page. You do not need to start a new check.

It is iPhone only

Stolen Device Protection does not exist on iPad. If you have an iPad to hand, the same check will finish on it without any delay.

Turning it off costs the same hour

Switching Stolen Device Protection off under Settings > Face ID & Passcode is itself a delayed action. If you are already inside a delay, waiting it out is the faster route.

Familiar locations skip it

iPhone does not impose the delay at places it recognises, such as home or work. Running the check there avoids it. If you have Significant Locations turned off, iPhone has nothing to recognise, so the delay applies everywhere.

If you opened the page in Safari or Chrome on iPhone

1Stay in Safari or Chrome and tap the main download button.

2Allow the iPhone configuration-profile prompt when it appears.

3If the prompt does not appear, reopen the same link in Safari and try again.

If you opened it inside Instagram, Gmail, Facebook, or another app

1Use the in-app share menu to copy or open the link externally.

2Choose Safari or Chrome if your app offers an explicit 'Open in Browser' action.

3If not, copy the link, open a normal browser yourself, then paste it there.

If you are on desktop or Android

1Open the UDID checker on the iPhone or iPad that actually needs provisioning.

2Use the QR code or copied link from the landing page to move the URL to the phone or tablet.

3Complete the entire profile flow directly on that device.

Reading the UDID from a computer instead

If the configuration-profile prompt will not appear at all, a cable still works. Both routes below read the identifier off the device directly, and neither one installs anything on it.

On a Mac, with Finder

1Connect the iPhone or iPad to the Mac with a cable and trust the computer if asked.
2Open Finder and select the device in the sidebar.
3Click the line under the device name that shows the model and storage. It cycles through serial number, UDID and other identifiers each time you click.
4Stop when the value matches one of the two UDID shapes below, then right-click it and copy.

On Windows, with the Apple Devices app or iTunes

1Connect the device and open the Apple Devices app, or iTunes on older setups.
2Open the device summary screen.
3Click the serial number until the label changes to the identifier you want.
4Copy the value and send it to whoever asked for it.

Two lengths are both valid

iPhones and iPads from the iPhone XS generation onward (A12 and newer) report 8 characters, a hyphen, then 16 more, for example 00008030-000A1B2C3D4E5F60. Older devices report a 40-character hexadecimal string. Send whichever one your device shows, exactly as it appears.

A serial number is not a UDID

Provisioning needs the UDID specifically. If the identifier line is still showing a serial number, keep clicking it until the value changes to the longer identifier.

Remove the temporary profile afterwards

Once the UDID has been captured, open Settings, then General, then VPN & Device Management, tap the BetaDrop profile and choose Remove Profile. The profile only exists to let the device report its own identifier back.

Quick checklist before retrying

Use the iPhone or iPad you actually want to register.

Open the BetaDrop UDID page in Safari, Chrome, or another full browser, not inside another app.

Tap the main download button and allow the configuration-profile prompt.

Return to the result page if the redirect does not happen automatically.

If the prompt still does not appear

Retry with the same URL, but change the environment

In-app browsers usually block the prompt

Instagram, Facebook, Gmail, and some chat apps keep you inside a limited browser shell. Copy the link and reopen it in a normal browser.

Desktop is only for handoff

You can start from desktop, but the configuration profile must be downloaded and installed on the exact iPhone or iPad you want to register.

Safari is still the safest fallback

Chrome on iPhone often works, but if the profile prompt is inconsistent, reopen the same page in Safari and retry there.
