How to Create a Passkey on an iPhone
Creating a passkey using an iPhone is relatively simple. In order to create one, though, you need to have:
An iPhone running iOS 16 or higher An account with a site or app that supports Passkeys.
Assuming you meet those requirements, here’s how to create a passkey: When you create a Passkey, it’s specific to the site you created it on just like a password is. So, for every site, app, or account you want to use a Passkey with, you’ll need to create a separate Passkey (assuming the site you want to use it with supports Passkeys, of course).
How to Use a Passkey on an iPhone
Once you’ve seen up a Passkey for a compatible site or app, you won’t need to use your password again. You can use the much more secure Passkey instead. Here’s how:
What Is an Apple Passkey and Why Is It Beneficial?
A Passkey might sound a lot like a traditional password and not necessarily worth the hassle of going through these steps. The more you know about Passkeys, though, the more their benefits seem clear. Passkeys rely on a long-standing security practice that uses a pair of encryption keys. In this situation, every Passkey you create has both a public key and a private key, which are paired with each other. When you set up a Passkey, the public and private keys are created. Your device sends the public key to the website you want to sign into and then uses the private key—which never leaves your device, unlike a password—to verify that you are really you. As mentioned above, the private key can only be used with the public key to access your account when you use Face ID or Touch ID. This is a crucial aspect of Passkeys: since those systems are so secure, and faking your biometric data is so difficult, the security is extremely high. So, the benefits of using a Passkey instead of a password include:
There’s No Password to Steal: Because Passkeys work with a key pair that can only be unlocked when together and with biometrics, phishing and hacking to steal your password literally can’t work. That’s pretty secure!Passkey Stays On Your Device: Passwords have to be stored on the computers of the company which you have an account with. That means that the password can be stolen from you or the company. That’s two risks. With Passkey, the highly secure private key always stays on your device, so the risk is lower.Face ID and Touch ID Are Highly Secure: Apple’s biometric-security systems are powerful and extremely difficult to fool, so the likelihood of them being hacked is low.Syncs with iCloud Keychain Across Devices: Once you create a Passkey, it’s synced using iCloud Keychain to all of your Apple devices using the same Apple ID. That’s easy!Compatible with Non-Apple Devices and Security Devices: Even though your Passkeys are stored on your Apple devices, you can use them on non-Apple devices via a shared QR code. Passkeys can also support security fobs used in many corporate environments.
