If you’re reading this, you’ve probably heard of two-factor authentication (2FA). It’s a solid security measure, adding an extra step beyond just a password to protect your online accounts. It used to the bee’s knees, the best of the best, the creme de la creme.
But now, there’s a new player in town: passkeys.
What makes passkeys different from 2FA? At first sight, they might appear to be very similar, but some distinct differences make the passkey worth learning more about. Let’s explore what sets them apart, how they work, and why passkeys are hailed as the future of secure logins.
What Are Passkeys?
Think of passkeys as your password-less authentication to the online world. Unlike traditional, single factor authentication methods, passkeys use a pair of cryptographic keys: a public key and a private key. The public key, which is like a lock that everyone can see but only you can open, is stored on the website or app you’re logging into. The private key, on the other hand, is like a key that only you have and is securely stored on your device.
How Does Passkey Authentication Work?
Logging in with passkeys is a breeze. When you want to access a passkey-secured account, your device uses biometric authentication (like Face ID or fingerprint) or a PIN to verify it’s really you. Once verified, your device combines the stored public and private keys to grant you access. The process is smooth and very user-friendly.
Why Are Passkeys Better Than Two-Factor Authentication (2FA)?
All this sounds an awful lot like Multifactor Authentication (MFA) or Two Factor Authentication (2FA). MFA/2FA typically adds a second layer of verification, like a code sent to your phone, on top of your password. It improves account security by requiring something you know (a password) and something you have (like a code sent to your phone). But it still has its flaws. For one, it relies on passwords, which can be stolen or phished. Passkeys, on the other hand, eliminate passwords, eliminating the incentive for hackers to steal or trick you into giving it up.
Comparing Passkeys and 2FA
Here’s a side-by-side comparison of why passkeys outshine 2FA:
- Password Elimination: Passkeys remove the need for passwords, reducing the risk of password-related attacks. 2FA still relies on passwords.
- Phishing Resistance: Passkeys don’t require you to enter a password or code, making them highly resistant to phishing.
- User Experience: Passkeys offer a seamless login experience using biometrics or a device PIN. In contrast, 2FA can feel cumbersome with additional steps like entering verification codes.
Passkeys: The Best Protection Against Phishing and Data Breaches
Phishing attacks are one of the most common tactics hackers use to steal login credentials, and passwords are a prime target because they’re often the key to multiple accounts. Once hackers get their hands on your password, they can:
- Access Your Accounts: A single stolen password can unlock everything from your email and social media to banking or business tools.
- Steal Sensitive Information: With access to your accounts, hackers can gather personal or financial data for identity theft.
- Spread Malware: Infiltrated accounts can be used to send phishing emails or malicious links to your contacts, perpetuating the scam.
- Sell Your Credentials: Stolen passwords are often sold on the dark web to other criminals for profit.
The extraordinary thing about passkeys is that there are no passwords to enter, so there is nothing for hackers to steal, removing all incentives for them to pursue your accounts. Without a password, fake emails and websites lose their power. Hackers can’t steal credentials that don’t exist.
Even if a website or app you used your passkey on gets breached, passkeys still offer robust protection against scams and unauthorized access:
- No Passwords to Steal: Passkeys eliminate passwords entirely, so there’s nothing for hackers to steal from the breached site.
- Unique Cryptographic Keys: Each passkey is unique to your device and the specific service. Even if a hacker gets hold of the public key from the breached site, they can’t use it without your private key, which remains securely on your device.
- Biometric Verification: Passkeys often rely on biometric verification (like fingerprint or facial recognition) or a PIN on your device. This adds an extra layer of security, making it nearly impossible for hackers to impersonate you.
Passkeys don’t just simplify your online experience; they provide peace of mind knowing your accounts are protected with cutting-edge security measures. It’s no wonder they are quickly gaining traction, with major tech platforms like Apple, Google, and Microsoft supporting them. While not every website or app uses this password-less authentication method yet, adoption is growing—and it’s worth considering this upgrade for your team. Passkeys combine simplicity and security, making them a smart choice for businesses and individuals alike.
