Sorry to be ignorant.
WTF is that?
It’s called a yubikey.
From website: The YubiKey offers superior security by combining hardware-based authentication and public key cryptography to effectively defend against phishing attacks and eliminate account takeovers. It offers multi-protocol support including FIDO2, Yubico OTP, OATH HOTP, U2F, PIV, and Open PGP.

It’s a foolproof method for stupid people like me to securely log into websites.
The yubikey is a physical device that you plug into your USB 4 computer port while logging in. You must physically press the yubikey button to log into your account on the website after you get the prompt from the website.
Because it’s a device that requires the user to physically activate it, it’s my understanding that it can’t be hacked.
I use it on financial sites.
Everything I wrote above was written by me - a stupid idiot. Do your own research and come to your own conclusions.
