If you have password-protected apps on your iPhone X£899 at Amazon UK, trying to remember usernames and passwords for each one can be a hassle. What's the solution? Use your face instead of a password to sign into supported apps.

Which apps actually work with Face ID? Any app supporting Touch ID will automatically work with Face ID, according to Apple. But you'll have to double-check on an individual basis. The app should tell you either directly or somewhere in its settings if it supports Touch ID or Face ID. Let's check out the process for using Face ID to sign into your favorite apps.

Set Up Face ID

You'll first need to turn on and set up Face ID if you haven't already done so; here's how.

Password-Protected Apps

Next, download and open an app that requires a password or other means of authentication. Tap on the Sign in button. Enter your username and password. The app may then present the option to sign in using Face ID. If so, tap on the button to enable it and confirm that you want to use Face ID. From then on, Face ID will automatically authenticate you when you need to sign into this app.

Quick Authentication

Some apps present you with the Face ID option before you even sign in. Enable the option and then sign in. The next time you again sign into the app, you're asked if you want to allow it to use Face ID. Tap OK, and Face ID will authenticate you.

Activate After the Fact

What if you ignored the option to use Face ID (or Touch ID) and have been signing into an app with a password? Sign into the app as usual. Then open the Settings section. If the app supports Face ID and/or Touch ID, you should see an option to enable that feature. If so, turn it on. The next time you have to sign in, Face ID should pop up to authenticate you.

In-App Activation

With other apps, you may be using multiple methods of authentication, such as a PIN and a password. Again, hunt around the Settings section for that app. Turn on the option for Face ID. The next time you sign in, Face ID should authenticate you.

Activate in Settings

What if you know an app supports Face ID or Touch ID, but it's not giving you that option? Beyond hunting around the app's settings, you can check another spot. On your iPhone, open Settings > Face ID & Passcode. Enter your passcode. Tap on the entry for Other Apps. If the app is listed but Face ID is not enabled, flip the switch to turn it on. Fire up the app again and see if Face ID is now available.

Log Into Websites With Face ID

You can also set up Face ID to log into websites you access via Safari; here's how.

My Experience

I've been working for PCMag since early 2016 writing tutorials, how-to pieces, and other articles on consumer technology. Beyond PCMag, I've written news stories and tutorials for a variety of other websites and publications, including CNET, ZDNet, TechRepublic, Macworld, PC World, Time, US News & World Report, and AARP Magazine. I spent seven years writing breaking news for CNET as one of the site’s East Coast reporters. I've also written two books for Wiley & Sons—Windows 8: Five Minutes at a Time and Teach Yourself Visually LinkedIn.

My Areas of Expertise

I've used Windows, Office, and other Microsoft products for years so I'm well versed in that world. I also know the Mac quite well. I'm always working with iOS, iPadOS, watchOS, and Android on my various mobile devices. And these days, I write a lot about AI, so that's become another key area for me.

The Tech I Use

My wife always jokes about all the tech products we have around the house, but I manage to put them to good use for my articles. I like Lenovo computers, so I own a couple of Lenovo desktops and several laptops. I have three MacBooks and a Mac mini. For my mobile life and work, I use an iPhone 16 Pro, iPad Pro, and iPad mini as well as an Apple Watch. But since I write about Android, I own several Android phones and tablets. Like any tech person, I have a cabinet full of cables, wires, and assorted mysterious gadgets. And when it's time to take a break from writing, I have an old Xbox 360 and Nintendo Wii, both of which I use for exercise and fitness games.
