Recently, a major wallet platform added passwords as a verification option. Now users have more methods to choose from—biometric passkeys, authenticators, traditional passwords, each with their own considerations.

Let's start with biometric passkeys (Passkeys). Security-wise, there's no doubt—FaceID, fingerprints, Windows PINs, these biometric methods are indeed robust. But there's an obvious issue—cross-device compatibility is a real hassle. Especially when using web browsers, they can't detect other local verification methods, and the option to scan a QR code with your phone simply doesn't pop up. Instead, you're often prompted with "Insert USB security key," which can be a bit frustrating.

Then there's the old-fashioned password verification. Simple, but easy to forget, and if set too simply, it becomes a security risk. Who still dares to use 123456 these days?

Authenticator apps are a solution developed by Google, using a pair of keys—one on the user side, one on the server side. During verification, a locally generated offline dynamic code is compared with the server. In terms of security, it's quite reliable.

So, which do you prefer? Each has its pros and cons; the key is whether it feels convenient and easy to use for you.
