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

The quality of the products is unquestionable – few can argue the superior quality of the Apple iPhone 15’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.

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

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

The Apple iPhone 15 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 model, you could use your watch to unlock your phone in any circumstances. It’s easy, secure, and convenient, above all else.
