How to Unlock Apple iPhone 15 Plus With an Apple Watch & What to Do if It Doesn’t Work

There are plenty of reasons why Apple devices are in such high demand. The quality of the products is unquestionable – few can argue the superior quality of the Apple iPhone 15 Plus’s camera, for instance. Almost all devices are long-lasting. They have a great resale value. They offer cutting-edge features.

However, perhaps the greatest advantage of Apple products is just how well they integrate with one another and work together.

With a quick little tap, you can have your Apple iPhone 15 Plus’s camera working as your Mac’s webcam. You can use your iPad as a second Mac display. Take calls using any device.

Moreover, you might be able to use the Apple Watch to unlock your Apple iPhone 15 Plus.

Now, you cannot just unlock any Apple iPhone 15 Plus with your Watch. The devices must be paired, and you’ll need to follow a few steps to enable this option. Here’s how to unlock your phone using your Apple Watch like a pro.

Part 1. Can I Use an Apple Watch To Unlock My Apple iPhone 15 Plus?

The Apple iPhone 15 Plus face ID is one of the simplest, most practical ways to unlock your phone. While you’ll need a passcode just as another security layer, you won’t have to worry about someone else breaking in if they know it, going through your messages, or collecting your private information.

With face ID, only you can unlock your phone, sign in to your favorite apps, and even authenticate purchases.

The problem is that neither face ID nor traditional passcodes aren’t always the most convenient option. If you wear sunglasses, safety goggles, a face mask, or other face coverings and can’t take them off for some reason, face ID won’t work. If you have gloves on and can’t type in your passcode, your passcodes won’t work.

What could work is your Apple Watch.

Depending on the Apple Watch version you own and your Apple iPhone 15 Plus model, you could use your watch to unlock your phone in any circumstances. It’s easy, secure, and convenient, above all else.

Part 2. Requirements for Unlocking Apple iPhone 15 Plus With Apple Watch

Unfortunately, not every Apple iPhone 15 Plus can be unlocked with your Apple Watch, and not every Apple Watch can unlock your Apple iPhone 15 Plus. Both devices must meet some requirements before you can adjust your settings to enable this option.

To be able to use your Apple Watch to unlock your phone with the utmost ease, you’ll need:

• An Apple iPhone 15 Plus with Face ID – Apple iPhone 15 Plus X and newer models;
• iOS 14.5 and newer versions;

• You need to have a passcode on your Apple Watch;
• Wrist detection on your watch needs to be turned on;
• The watch needs to be on your wrist and unlocked.

You’ll also need to wear items such as sunglasses, face coverings, ski masks, or others that prevent you from using your Apple iPhone 15 Plus Face ID.

Part 3. How To Unlock Apple iPhone 15 Plus With an Apple Watch

If you meet all the aforementioned criteria, setting up the feature to unlock your Apple iPhone 15 Plus using an Apple Watch is easy. You’ll just have to follow a few steps:
