Using the Personal Hotspot feature in iOS 7 on your iPhone 5 allows you to share your cell phone’s data connection with other devices. This is a great way to access the Internet from your computer or tablet when you aren’t near a wireless network. But the data that you use on your iPhone is more expensive than the data you use on your home or work network, so it’s important to restrict access to your hotspot. So if someone else knows the password for your hotspot and is using it, then you need to change your personal hotspot password to restrict their access.
Change the Password for Your iPhone’s Wi-Fi Tether
Note that this will require you to change the password on any device that automatically connects to your iPhone’s Wi-Fi, such as your laptop or iPad. It will also prevent anyone who was previously connected to your hotspot from connecting again unless you give them the new password.
Step 1: Touch the Settings icon.
Step 2: Touch the Personal Hotspot option near the top of the screen.
Step 3: Touch the Wi-Fi Password button.
Step 4: Touch the x button to delete the previous password, enter the new password, then touch the Done button.
If you are concerned about other people reading the information on your iPhone, then a passcode can be a helpful thing to have. Learn how to set a passcode on the iPhone 5.
