Passkey

The Passkey Extension for Magento 2 enables administrators to log in using a passkey. It enhances the user experience by simplifying the login process while maintaining high-security standards. This is ideal for shop administrators who wish to log in without a password while still ensuring security. This way, the module extends the Two-Factor-Authentication process and adds a passkey as an additional possibility to login. 

Features

• Easy Login: By Passkey you can log in without using your username and password.
• Secure: Passkey is a secure way to log in. It is resistant to phishing attacks and data breaches.
• Easy to Use: The Passkey module is easy to use and can be used by anyone.
• Customizable: It is possible to allow only specific admin users to use the Passkey.
• Multi-Device Support: Login with different devices like a mobile phone, tablet, or Yubi-Key.

What is a Passkey?

A passkey is a modern authentication method that replaces traditional passwords. It combines a user's device and biometrics (like fingerprint or facial recognition) to securely log in without needing to remember or type a password. Passkeys are based on public-key cryptography, making them resistant to phishing and password breaches.

For a deeper understanding of how passkeys work and why they're secure, please take a loot at this detailed explanation.

Why Passkeys Are Secure

No Passwords to Steal

Passkeys don’t store or transmit passwords. Instead, they use a unique pair of keys:

• Private Key: Stored securely on your device and never shared.
• Public Key: Stored on the service's servers and used to verify your identity. Hackers cannot steal the private key because it never leaves your device.

Phishing Resistance

Traditional passwords can be stolen through phishing attacks. Passkeys are resistant because authentication happens directly between your device and the service. No sensitive data is entered into potentially malicious websites.

Biometric Protection

Passkeys often use biometric authentication (fingerprint, face recognition) or device-based PINs. These are harder to replicate and never transmitted, making unauthorized access difficult.

Tied to Physical Devices

A passkey is bound to a specific device, meaning even if someone knows your credentials, they cannot log in without your device.

Resistant to Data Breaches

Since only the public key is stored on the server, even if the server is breached, the stolen data is useless without the corresponding private key.
