Passwords weren’t built for today’s internet. Passkeys are.
The Password Problem
When you log in with a password, you're relying on a two-part system: a public username and a secret password. But in practice, that "secret" isn't very secret at all.
You share it with the service you’re accessing, and it’s stored on a server for verification. Your security depends not only on the strength of your password but also on every system that stores or transmits it. In a world of automated attacks, deepfakes, and massive breaches, that’s a fragile setup.
A Legacy System in a Modern World
Passwords weren’t designed for today’s internet. Originally built for small, closed systems, they've been stretched far beyond their limits to serve billions of users, devices, and services.
The consequences?
Phishing: Fake emails and websites trick users into handing over their credentials.
Credential stuffing: Attackers reuse leaked credentials across services, exploiting widespread password reuse.
Social engineering: Deepfake audio and AI chatbots can now impersonate colleagues—even CEOs—to bypass security layers.
Even with two-factor authentication (2FA), the fundamental problem persists: passwords can be intercepted, guessed, or stolen.
FIDO2 and Passkeys: Rethinking Authentication
FIDO2 introduces a radically different model based on public-key cryptography. Instead of sharing secrets, it uses a unique pair of keys:
A public key, stored by the service.
A private key, securely stored on your device and never shared.
When you log in, your device signs a one-time challenge using the private key. The service verifies it using the public key. That signature can’t be faked—and it only works for that service.
No passwords. No shared secrets. No central database of credentials to steal.
Why Passkeys Are Winning
Passkeys are a user-friendly implementation of FIDO2. Instead of managing multiple usernames and passwords, it ties your identity to your device. You unlock it with a local PIN or biometric your fingerprint, face, or voice—and the device handles the secure handshake behind the scenes.
According to the FIDO Alliance, passkey adoption doubled in 2024, enabling secure access to over 15 billion accounts. Industry giants like Google, Microsoft, Amazon, and others are shifting away from passwords altogether.
This isn’t just a feature update—it’s the foundation for a new, more secure identity infrastructure.
Passkeys vs Deepfakes: A Modern Defense
In early 2024, employees at a multinational firm in Hong Kong were scammed into transferring $25 million after attending a video call with a deepfake impersonation of their CFO. The likeness was so convincing that no one suspected fraud, until it was too late.
This incident shows how traditional verification methods such as passwords, video calls, even security questions can now be convincingly spoofed.
FIDO2 passkeys eliminate this risk. Because the login requires your device and your biometric or PIN, authentication is tied to cryptographic proof, not visual appearances. Deepfakes can’t fake a private key.
