How to Remove Someone Else's Apple ID from Your iPhone without Knowing the Password

It can be frustrating to have someone else's Apple ID linked to your iPhone, especially when you don't know the password. However, there are steps you can take to remove the unwanted Apple ID and protect your device's security.

One way to resolve this issue is by contacting Apple Support. They may ask you for proof of ownership of the device and help you remove the unknown Apple ID.

If you can access the device, you can try going to Settings > iTunes & App Store, tap on the Apple ID, and choose 'Sign Out.' Then, sign in with your own Apple ID to link the device to your account.

If all else fails, you can restore your iPhone to factory settings to remove the unwanted Apple ID. However, this will erase all data on the device, so be sure to back up important information beforehand.
