How to use Apple Passkeys on iOS 16

Remembering all the passwords you have is not easy, and they are not that safe either because one needs a few basic details about you or access to your device to figure out the password to your email. Not always, but in most cases, it is possible.
What if we tell you that you will not need to remember passwords? Apple‘s Passkeys eliminate the need to remember passwords or even type them to log in. And it is far more secure than the good old passwords.
But there is a catch. Passkeys are available for select apps and websites and only on iOS and macOS. Soon, it would be coming to Android, as well, with a promise to add more services.
What are Apple Passkeys
Passkeys are unique digital keys, to be exact, a pair of public and private cryptographic keys that ought to replace passwords. The Passkeys are based on FIDO Alliance and W3C standards and use Apple’s Keychain to sync the keys across Apple devices. These work with the Face ID and Touch ID found on iPhones, iPads, and Macs.
How do Apple Passkeys work
The Passkeys on Apple devices work similarly to Keychain, which auto-fills the username and password. But with Passkeys, there is no password to fill in.
You need to create the account as you do, but there is no need to think of a password, as it gets replaced by a “unique” cryptographic key pair that can never be guessed or used, unlike passwords.
So, whenever you log in or create an account, the device and service exchange public-private cryptographic keys to prove the user’s identity. The device itself confirms the user’s identity using Face ID or Touch ID, depends what device you are using.
The private key gets saved on the iCloud Keychain, and the service or website saves the other. Thus, you can log in using any of the devices linked to your Apple ID.
Which apps or websites support Apple Passkeys
Only a handful of services support the Passkeys as of now. These are Twitter, WordPress, Microsoft, Zoho, Facebook, Github, Paypal, GoDaddy, Google, Kayak, and Paypal, to name a few. Though, the Passkeys would soon be available on Chrome and Android devices, letting users log in using their iPhones.
