Automatic passkey updates in iOS 18 and macOS Sequoia

With the release of iOS 18 and macOS Sequoia, Apple introduces a groundbreaking feature that allows websites and apps to automatically update existing logins to passkeys.

What are passkeys?

Passkeys are the future of secure logins. They replace traditional usernames and passwords with a more robust and user-friendly approach.

Instead of remembering complex character combinations, you simply use your fingerprint, Face ID, or a secure PIN to log in to websites and apps. With Passkeys, the login credentials are never stored on servers, eliminating the risk of data breaches and phishing attacks.

iOS 18

One of the most exciting aspects of Passkeys in iOS 18 and macOS Sequoia is the automatic update feature. This feature, enabled by default, allows websites and apps to automatically convert your existing login credentials into Passkeys.

With a simple prompt, your existing logins get a security upgrade, making the transition from passwords to Passkeys incredibly smooth. Here’s how it works:

  • Detection: When you log in to a website or app that supports passkeys, the system detects if your existing login can be updated.
  • User prompt: A prompt appears, asking if you would like to update your login to a passkey. This process is designed to be straightforward, requiring minimal user input.
  • Secure conversion: Upon user confirmation, the system securely converts the login credentials to a passkey. The new passkey is then stored in the secure enclave of your device.


Applications and adoption

As more websites and apps adopt passkeys, users will experience a more secure and streamlined login process across various platforms.

Major tech companies and service providers are gradually integrating passkeys into their authentication systems, paving the way for widespread adoption. Enhanced security measures are critical in sectors such as banking and financial services, making passkeys an attractive option for protecting sensitive financial data.


The introduction of automatic passkey updates in iOS 18 and macOS Sequoia is a monumental step towards enhancing digital security and user convenience. By making it easy to transition from passwords to passkeys, Apple is paving the way for a safer and more user-friendly digital environment.
