Handing Over a Used iPhone: How Stolen Device Protection Delays Signing Out by an Hour
· TR Vertriebs GmbH
The iPhone 18 Pro has been on sale since Friday. Anyone selling their old iPhone now should know: since iOS 26.4, Stolen Device Protection is on by default – and signing out only at the meeting means waiting an hour. How sellers and buyers should prepare the handover.
The iPhone 18 Pro has been available in Germany since Friday, 18 September. It starts at 1,449 euros – 150 euros more than the iPhone 17 Pro cost at launch a year ago – and the iPhone 18 Pro Max starts at 1,599 euros. Anyone switching who wants to sell their current iPhone privately now faces a hurdle that did not exist in this form at last autumn's model change: since the update to iOS 26.4, Stolen Device Protection is switched on by default – and it slows down exactly the steps a handover requires.
With iOS 26.4, released on 24 March 2026, Apple turned the feature on by default for all users; it was introduced with iOS 17.3, when users had to enable it themselves. It is designed to stop a thief who has obtained both the iPhone and its passcode from taking over the account and the device. Away from familiar locations – according to Apple typically home, work and other places where the iPhone is used regularly – the iPhone requires Face ID or Touch ID for certain actions, with no option to enter the passcode instead. For particularly sensitive actions, a waiting period is added.
This Security Delay lasts one hour: first Face ID or Touch ID, then a wait, then a second biometric authentication. According to Apple's support document on the feature (version of 31 March 2026), it applies, among other things, to signing out of the Apple Account, changing the Apple Account password and the device passcode, resetting all settings and turning off Stolen Device Protection itself. In addition, Find My cannot be turned off while the protection is active. Yet signing out and releasing Find My are exactly the steps needed so that a sold iPhone is no longer tied to the previous owner's Apple Account.
For a handover, this means: a car park, a café or a railway station is usually not a familiar location for the seller's iPhone. Anyone who only wants to sign the device out of their Apple Account there will run into the waiting period. Apple itself writes in its guide to selling and trading in that changing your password in an Apple Store is likely to trigger a one-hour Security Delay. And Apple explicitly recommends turning off Stolen Device Protection before selling, giving away or trading in an iPhone.
Sellers should therefore do the preparation at home before setting off to the meeting. There the delay does not apply, unless they have chosen in the settings to require it always. The order: make a backup and transfer the data to the new iPhone, unpair any Apple Watch, turn off Stolen Device Protection under Settings > Face ID & Passcode, then tap your name in Settings and choose Sign Out, and finally erase all content and settings under General > Transfer or Reset iPhone. If the iPhone uses an eSIM and asks what to erase, Apple recommends erasing both the device and the eSIM profile. If you have AppleCare, Apple says the plan can be transferred to the new owner.
Buyers should not rely on promises but check the result. A correctly prepared iPhone starts with the setup assistant. If it asks for the previous owner's Apple Account during setup, Activation Lock is active – and the device cannot be used by a new owner. Check before the meeting with an IMEI check whether Find My is still switched on, and only pay once the device is free. “I'll sign it out later” is not a solution: as long as the iPhone remains in the seller's account, they can lock it remotely or mark it as lost at any time – or simply forget.
If the seller still turns up with an iPhone that is signed in, there are two clean options: wait out the hour together and complete the sign-out on the spot, or reschedule the meeting. According to Apple, the iPhone can end the delay early if it detects that it has returned to a familiar location – so meeting at the seller's front door may solve the problem. Any arrangement in which you pay first and the device is only to be released later is risky.
Sellers need to be alert these weeks too. In mid-September, police in the Westpfalz region of Germany warned of a scam on the classifieds platform Kleinanzeigen: supposed buyers suggest completing the deal via the “Direkt bezahlen” (pay directly) function. The seller then receives a message forged by the fraudsters claiming the sale has been completed and is asked to carry out a “verification” on a fake page via a link or QR code – including transferring a larger sum of money. The police make it clear: in a genuine sale through the official system, sellers are never asked to transfer money for verification.
The short version for both sides: turn off Stolen Device Protection, sign out and erase – at home, not at the meeting. Buyers check the IMEI in advance, ask to see the setup assistant on the spot and only pay once no prompt for someone else's Apple Account appears. With IMEI Safe, you can see before the meeting whether the IMEI is on a blacklist and whether Find My is still active.
