When it comes to securing our online accounts, two-factor authentication (2FA) and passkeys are two popular methods, but how do they differ? Let's break it down.

 

Two-factor authentication (2FA) traditionally requires something you know (your username and password) and something you have (a second factor, like a code sent to your phone). While effective, 2FA can still be vulnerable to phishing attacks. For example, if an attacker tricks you into revealing your login details, they could potentially access your account.

 

Passkeys, on the other hand, aim to eliminate these risks. A passkey works as a first-factor authentication, replacing the need for passwords entirely. Instead of typing in a password, you authenticate using a cryptographic key that is unique to you. This makes passkeys resistant to phishing because they can’t be reused across sites and are tied to a specific service.

 

One of the main benefits of passkeys is that they can't be stolen or phished in the same way a password can. They use a secure, encrypted challenge-response system, making it nearly impossible for attackers to gain access, even if they intercept the data.

 

While passkeys are gaining traction, they are still not universally supported. Major players like Google and Microsoft are leading the charge, but many smaller sites have yet to adopt them. Additionally, moving passkeys between devices, especially across platforms (e.g., from iPhone to Android), can be tricky.

 

So, what’s the takeaway? If you can use passkeys, it’s a safer bet than relying solely on passwords. However, for those still using passwords, a password manager with strong, randomly generated passwords is a must. Remember, password reuse is one of the biggest security risks, so always use different passwords for different sites.
