Guide to Using Passkeys in Apple Passwords App on iPhone

Essential Information About Passkeys

• Passkeys offer a more secure and efficient alternative to conventional methods for logging into apps, websites, and services.
• The Passwords app in iOS 18 enables users to create, store, log in with, and easily access all of their passkeys in one organized location.
• Users can generate passkeys on their iPhone or other devices, with the option to save them to the Passwords app via iCloud Keychain.
• Passkeys are applicable for signing in on any device using your Apple ID.

Since their introduction in iOS 16, Apple has advocated for the adoption of passkeys. This revolutionary, password-free method of accessing websites and applications has been further enhanced with the standalone Passwords app in iOS 18.

If you’re looking to eliminate the frustration of juggling different passwords and the associated security concerns, here’s how to utilize passkeys through Apple’s Passwords app in iOS 18.

Understanding Passkeys

Passkeys enable users to log into apps and websites without relying on passwords. Developed by the FIDO Alliance, a passkey operates based on the precise alignment of two keys: a ‘private’ key stored on your device and a ‘public’ key retained by the website or service you are accessing.

For authentication to be successful, these two components must match perfectly. This concept is similar to a physical vault where both the vault’s lock and your key must coordinate seamlessly.

Notably, you do not need to memorize your key, as it’s securely saved on your device and verified through your device’s biometrics (like Face ID) or a PIN. This feature makes passkeys considerably safer, as their security is not dependent on users’ ability to remember complex and unique passwords.

However, it is important to note that passkey support is still limited. While the adoption rate is increasing, only a select few dozen services currently support this new technology. For a community-driven list of these websites, apps, and services, you can check here.
