A security key is a good option to use for two-factor authentication when logging into certain websites.
With the Windows Hello and FIDO2 standards, you can authenticate supported website logins through different methods, including facial recognition, fingerprint recognition, a PIN, or a physical security key.
If your computer doesn't support facial or fingerprint recognition, and you don't want to rely on a PIN, a physical security key offers an effective way to authenticate your account logins.
For older computers with just USB-A ports, the YubiKey 5 Series, Security Key Series, and YubiKey FIPS Series all have the proper connections.
