Passkeys
Passkeys are a modern, passwordless authentication method designed to improve security and convenience. They are based on public-key cryptography and are meant to replace traditional passwords. Here’s how they work and why they’re beneficial:
How Passkeys Work
1. Key Pair Generation:
• When you create a passkey for a website or app, your device generates a public and private key.
• The public key is stored by the website, while the private key remains securely on your device.
2. Authentication Process:
• When you log in, the website sends a challenge that your device signs using the private key.
• This signed response is verified with the public key stored by the website.
• Since only your device has the private key, the authentication is secure.
3. Biometric or Device Authentication:
• Instead of entering a password, you authenticate using Face ID, Touch ID, Windows Hello, or a PIN.
Benefits of Passkeys
✅ More Secure – No passwords to steal via phishing or data breaches.
✅ Convenient – No need to remember or type passwords.
✅ Resistant to Phishing – Passkeys are tied to specific websites and can’t be used elsewhere.
✅ Multi-Device Support – Can sync across devices via iCloud Keychain, Google Password Manager, etc.
Where Are Passkeys Used?
• Apple, Google, and Microsoft support passkeys in their ecosystems.
• Websites and services like PayPal, eBay, and some banks are adopting them. See a directory HERE
How to Use Passkeys
• When signing up or logging in to a service, choose “Sign in with a passkey” instead of a password.
• Authenticate using your fingerprint, face scan, or PIN.
• Passkeys can be synced across devices or transferred via QR codes.
