How to Embrace Passkeys for Enhanced Online Security
In today’s digital world, Passkeys are emerging as a game-changing solution in online security. They effectively eliminate the need for remembering usernames and passwords, making your online experience smoother and safer. However, many people find the concept of Passkeys confusing. If you’re one of them, don’t worry—we’ll break it down for you!
What Are Passkeys?
Passkeys are part of a technology called WebAuthn, which stands for Web Authentication API. This web standard was developed by the FIDO Alliance and the W3C to facilitate secure, password-free sign-ins using methods like biometrics, security keys, and other cryptographic techniques. With Passkeys, you can log into websites and apps that support this system without using traditional passwords. This not only enhances your security but also helps to reduce the risk of phishing attacks.
How Do Passkeys Work?
Using Passkeys for the First Time
- When you visit a website that supports WebAuthn for the first time, you will be prompted to use a Passkey.
- If you choose to proceed, your device (be it a Mac, iPhone, or security key) will create a unique pair of cryptographic keys: a private key and a public key.
- The private key remains securely stored on your device (or in a secure storage option like iCloud Keychain or 1Password), while the public key is saved on the website’s server.
Logging In Again
- On your next visit to the site, the website’s server will send a challenge to your device.
- Your device will respond to this challenge by "signing" it with the private key (which never leaves your device).
- This signed response is sent back to the website for authentication via the public key.
- If everything matches, you’ll be granted access—passwords are unnecessary!
Where Are Passkeys Stored?
Understanding where to find your Passkeys is key to making the most of this technology:
- Apple Users: If you’re in the Apple ecosystem, your Passkeys are likely stored in the Keychain or Passwords app on your device.
- Third-Party Password Managers: Using a service like 1Password or Dashlane? Your Passkeys will be kept securely in their respective vaults.
- Physical Security Keys: If you use a physical security key from companies like Yubico, like for Two-Factor Authentication (2FA), the Passkeys are stored on the hardware itself. This adds an extra layer of security.
- Local Devices: If you don’t sync with the cloud, your Passkeys will only be stored on the local device. Each device will require its own unique Passkey.
By understanding how Passkeys work and where they are stored, you can significantly enhance your online security. Embracing this new technology is a smart move that will make your online activities simpler and more secure.
Now that you have the basics down, it’s time to start using Passkeys and enjoy a password-free experience!
