Hey everyone! I'm new to this forum and I'm really curious about improving security and privacy for my PC and online accounts. I've been reading about these USB keys for two-factor authentication. Is it actually possible to make one myself?

Are you thinking about something like a FIDO key? Those are pretty popular for 2FA.
Why not just buy a USB key? They’re fairly inexpensive, but it looks like they can be pricey in Brazil. That’s a bummer!
Most modern 2FA keys aren’t just regular USB drives. They typically have their own microprocessors that generate keys and manage the connection securely. Honestly, if you're asking about building one yourself, it's probably better to buy a reliable key from a well-known maker like YubiKey, or you can use an app like Authenticator for two-factor authentication.
Just get a pre-made key or stick with an app for now. It'll save you the hassle.
