Apple’s introduction of passkeys means you can authenticate to some apps and services with Face ID or Touch ID instead of remembering a password. Here’s how to get started.
Passkeys were unveiled at WWDC 2022 in June and rolled out as a feature in iOS 16, iPadOS 16, and macOS Ventura. Passkeys are a way for users to authenticate to apps and online services. The key is that it does this without requiring the user to enter a password as a form of identification.
Passkeys contribute to the often speculated passwordless future, where devices and apps can confirm the person’s identity without much interaction. While users still need to do things to verify their identity in some way, Passkeys does it in a different way than the usual password.
Aside from not having to enter a password, passkeys offer a few advantages, including using strong end-to-end encryption and not having an easy-to-guess password to worry about. There are also ways to share passkeys with AirDrop and use them on other linked Apple devices and even non-Apple hardware.
How do passkeys work?
Passkeys, a standard developed by the FIDO Alliance and the World Wide Web Consortium, are cryptographic keys associated with a device to validate an identity. The passkey actually consists of a public and private pair, with the former being registered with the service itself and the private being stored securely on your device.
This public-private arrangement has been done before and is commonly used in cryptographic applications. By exchanging keys, the device and the service or app can confirm the match records of the device and its current user and prove their identity.
The device itself must confirm the user’s identity before the exchange takes place. This is handled through biometrics, which could be Face ID or Touch ID on an iPhone.
After biometric verification, the device performs its exchange with the appropriate service and access is then granted.
What can I use Passkeys with?
Because it’s a relatively new security standard, it may take some time for online services to adopt it. With the introduction of passkeys by Apple and their acquisition by Google and Microsoft, more online destinations should be using them for authentication over time.
As you might expect, the list of well-known apps and online services that work with passkeys is relatively small, but it’s likely to grow pretty quickly.
As of November 15, 2022, the top services that can use Passkeys include:
- best buy
- Go Daddy
How to start using passkeys
There are a few things you need to do in order to use Passkeys. First, your hardware should be updated to iOS 16, iPadOS 16, and macOS Ventura.
You should make sure iCloud Keychain is turned on so they can sync with other Apple devices. It’s best to do this beforehand, but you’ll be prompted to enable it if you create a master key with the key disabled.
How to turn on iCloud keychain in iOS 16
- Open settings.
- Beat passwords and authenticate.
- Beat Password Options.
- turn on Autofill passwords.
- Make sure there is a check mark next to both instances of iCloud passwords and keychain for the Allow filling of and Set up verification codes with sections.
You must also enable two-factor authentication for your Apple ID.
How to enable two-factor authentication for an Apple ID
Beat Passwords & Security.
Beat Enable two-factor authentication and follow the instructions.
This is where you can set up and manage passkeys on your device.
The process of setting up a passkey generally follows the same steps across the industry, with a few minor differences when getting started.
How to set up passkeys for a new account on your iPhone
- Sign up for a on the sign-up or account creation screen for a supporting app or website in Safari New accountincluding entering an account name, email address or whatever is asked.
- If passkeys are supported, you will be asked in a pop up if you want to save a passkey. Beat continue.
- If the pop-up doesn’t appear immediately, look for an option Use Passkey or some form of “other” authentication. When the popup appears, tap Continue.
How to set up passkeys for an existing account on your iPhone
- For an existing account log into the account as usual.
- open that Account Management Screen for that app or website.
- Look for one corresponding option within the account settings, which may contain password or security related items. This can be under a Hardware Security Device or Multi-Factor Security section.
- You will generally see an option Add a passkeywhich will invoke the passkey popup.
- Beat Continue.
How to sign in with Passkeys on an iPhone
- open that Login or login page of the app.
- If Passkey has been activated for this service, a pop up is usually displayed and you will be asked if you want to sign in. Tap on Continue and complete the authentication prompt.
- Some websites may require you to enter one email address or username before the popup appears. If so, click Continue and complete the authentication prompt.
Once you’ve started using passkeys, you can use your iPhone to manage how they’re used. For example, you can view and delete all passkeys on a device.
To access the list, open Settings and then tap Passwords to view the list. Tap each passkey to see options such as B. add notes to a master key or delete it directly.
