A passkey is a modern alternative to traditional passwords, designed to make your online accounts more secure and easier to access. Instead of remembering complex passwords, a passkey uses cryptographic keys stored on your device. This means you can log in securely without the hassle of typing in a password each time.

Passkeys simplify the login process by using a combination of a public and a private key. When you create a passkey for an account, your device generates these keys:

• Public Key: This is stored on the service's server and is not sensitive.
• Private Key: This remains on your device and is used to verify your identity.

When you log in, the service sends a challenge to your device. Your device uses the private key to sign the challenge, proving your identity without ever sending your private key over the internet. This makes the process fast and secure!

Absolutely! Passkeys are designed to be highly secure. Since your private key never leaves your device, it’s much harder for hackers to steal your login information. Additionally, even if a malicious actor gains access to the server, they cannot retrieve your private key. This security model significantly reduces the risk of account breaches and phishing attacks.

Passkeys often incorporate biometric authentication methods, like fingerprint scans or facial recognition, enhancing both security and convenience. When you use biometrics, your device verifies your identity before allowing access to your accounts.

Privacy is a priority with passkeys. Your biometric data is stored locally on your device and is not shared with the service provider. This means you can enjoy secure logins without worrying about your sensitive information being compromised.
