Your iPhone has a Personal Hotspot feature that allows you to share the device’s cellular Internet connection with other Wi-Fi devices like a laptop computer or an iPad. This is a great way to get those devices on the Internet when you aren’t able to access a traditional Wi-Fi network like the one you might have in your home or at work.
The password for your Personal Hotspot doesn’t change, however, which means that any device that has previously connected to your iPhone’s Personal Hotspot in the past would be able to do so whenever your Personal Hotspot is active. So if, for example, there is someone in your office, or a roommate, that keeps trying to use your Personal Hotspot and they are causing you to use a lot of data, then you can follow the steps below to change your Personal Hotspot password.
