While it’s always a good idea to wipe your iPhone before selling it or passing it on to someone else, it’s not uncommon for some folks to forget this important step, especially if they’re just handing an old iPhone down to a friend or family member. Hence, if you’ve acquired a used iPhone from somewhere, you may find that it’s still signed into the Apple ID of the previous owner, which can be a pretty frustrating situation as it makes it difficult for you to make your new iPhone truly your own.
Depending on whose Apple ID you’re using, this may be more than just an inconvenience. Using an iPhone that’s fully signed in to someone else’s Apple ID means that you’ll be syncing data like your photos and messages with their iCloud account instead of yours, and it’s likely they can even track its location via Apple’s Find My iPhone. Even if they’re a close friend or immediate family member, you may not want them to have that level of access to your personal life.
If you’ve let someone else use your iPhone, it’s also possible that they’ve logged into their Apple ID to download something from the App Store or iTunes Store. This is far less of a privacy concern since the iPhone is still using your Apple ID for iCloud and other important information; however, you’ll still have trouble downloading or purchasing apps and installing updates in this case, so it’s best to switch that back to your own Apple ID.
Thankfully, most of these problems are easily solvable as long as you otherwise have full access to the iPhone and know its passcode or password. Let’s walk through the different scenarios.
Removing an Apple ID from your iPhone is quite easy as long as you have the password. If the previous owner is nearby, you can hand them the iPhone and let them key it in themselves, or if they trust you enough, you can ask them to give you their Apple ID password over the phone.
Either way, you can sign their account out of your iPhone by doing the following:
Once that process completes, you’ll be returned to the main screen of the Settings app, where the name will have been replaced with a Sign in to your iPhone prompt. Select this and follow the steps to sign in with your own Apple ID.
If you don’t have the former owner of your iPhone within arm’s reach and they’re unwilling to give you their iCloud password, you can ask them to remotely erase your device and remove it from their account using Apple’s Find My iPhone feature. However, this will erase everything from your iPhone and return it to factory settings.
That may not be a problem if it’s an iPhone you’ve just acquired, but if not, you’ll want to make sure you’ve backed it up to your Mac or PC before proceeding. An iCloud backup won’t do in this case, as you’d be backing up your data to the other person’s iCloud account, and you won’t be able to restore it from there without signing in to their iCloud account again, which kind of defeats the purpose of this whole exercise.
Here are the steps the other person should follow to wipe and remove your iPhone from their account. Note that Find My iPhone must have been enabled on the device for this to work. However, that’s usually the default, and if Find My iPhone is not enabled, then you can skip to the next section, as you won’t need a password to sign out of the other person’s Apple ID.
Once this is all done, your iPhone will be at the welcome screen, just as if you’d taken it out of the box brand new. You can then proceed to follow the instructions to set it up with your own Apple ID. If you made a backup on your computer that you want to restore, you’ll be given a chance to do this during the setup process.
If you don’t know or can’t find the previous owner or can’t get them to cooperate with you, then things may be a bit more complicated.
In the very unlikely scenario that the previous owner didn’t have Find My iPhone enabled, then you don’t need their password to sign out of their Apple ID. Just follow the steps in the first section to find the Sign Out button. You won’t be prompted for a password since this is only necessary as a security feature to turn off Find My iPhone.
However, since Find My iPhone is enabled by default, it would need to have been deliberately and specifically switched off. In most cases, it will be enabled, so you’ll need to have the other person’s Apple ID password to disable it.
Depending on the version of iOS that’s running on your iPhone and whether it was set up as a “trusted device” by the previous owner, you may be able to change their Apple ID password using the device passcode — assuming it has one. However, this will lock the person out of their Apple ID on all of their other devices, creating some confusion and forcing them to figure out how to reset their password again.
Whether this is an appropriate move depends on the circumstances. While it seems fair if the previous owner is deceased or no longer uses that Apple ID, in other situations, it would be good to do your best to contact the original owner before taking this step. Nevertheless, if you’ve decided this is what you need to do, here’s how to go about it:
Once you’ve changed the Apple ID password, you can return to the previous section and sign out of the Apple ID using the new password.
Changing the Apple ID password using the device passcode won’t be possible in every situation. For this to work, the iPhone has to have a passcode in the first place — you can’t add one later just to change the Apple ID password, as you’ll need to enter the Apple ID password to set one. The iPhone also has to have been set up as a “trusted device” for the person’s Apple ID.
In most cases, both these things will be true, so it’s worth a try, but if you don’t see the option to use your passcode to change the Apple ID password, there won’t be anything else you can do. There’s also a chance that Apple could take away this capability in the future, following a recent Wall Street Journal report that thieves have been exploiting it to lock people out of their own Apple accounts.
If the previous owner had Find My iPhone enabled on their device and you’re unable or unwilling to reset their Apple ID password using the device passcode, then, sadly, you’re stuck. Apple’s Activation Lock feature does a very good job of making stolen iPhones useless to thieves as anything more than spare parts. There’s no way around the Activation Lock that will result in an iPhone that works normally; sites that purport to bypass Activation Lock are either outright scams or involve “jailbreaking” tools that will prevent the iPhone from being used with most Apple services, including iCloud and the App Store.
Even if you use the brute-force “DFU” method to factory reset the iPhone, you’ll still be confronted with a prompt to enter the original owner’s Apple ID and password before you can set it up unless the original owner removes it from their account via the Find My app or web portal.
In some cases, you can lend your iPhone to a friend or relative, who then proceeds to download apps onto your iPhone via the App Store using their own Apple ID. If they don’t sign out of the App Store before giving you the iPhone back, you’ll inevitably find that you can’t download new apps since you’ll be asked for their Apple ID password instead of yours.
Luckily, signing them out of the App Store is easy and doesn’t require a password. This method can also be used if you’ve bought a used iPhone and the previous owner’s Apple ID is still on it, although we’d strongly recommend dealing with the system-wide Apple ID since, otherwise, the previous owner will have far more access to your iPhone and your personal data than they should.
Here’s how to switch the Apple ID that’s used for Apple services, including the App Store, Apple Music, Apple TV, Apple Podcasts, the iTunes Store, and more.
This technique is also useful for anyone who needs to switch App Store accounts on their personal device for any reason, such as if you have multiple accounts in different countries. Just be aware that the account here covers all of Apple’s services, including Apple Music and Apple TV+, but it doesn’t affect other features such as iCloud, FaceTime, and iMessage.
Also note that if you’ve bought and downloaded apps using a different Apple ID, those apps will require you to log in to that previous ID to get those updates. If you’re in that situation, it may be best to delete that app and download it again under your new Apple ID.
Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.
Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.
Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.
I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.
Apple's first foldable phone is now on shelves, in short supply, but with an unreal amount of buzz around it. After all, it's the first foldable iPhone, and there's plenty that this phone gets right. But there's also a lot that is either broken or underwhelming. What's peculiar is the dialogue around this phone, and how it has completely overshadowed every other attempt at making a phone with a similar form factor.
I've spent some time with the iPhone Duo, and I've used the Galaxy Z Fold 8 for almost three months now. In my opinion, Samsung deserves more credit. When the Galaxy Z Fold 8 arrived earlier this year, it was celebrated in some circles and ridiculed in others for supposedly copying what Apple would eventually deliver with the iPhone Duo. The dialogue was pretty odd, for multiple reasons. Samsung has been making foldable phones for years, so claiming that it copied a product Apple hadn't even launched was simply absurd.
