What I liked
Two-factor authentication hardware tokens vary in their features and connection methods. Some models work via USB, like the YubiKey, and require physical contact for verification. There are also NFC-enabled options, which are convenient for use with mobile devices. Other models generate one-time passwords directly on their display, making them standalone and independent of the phone. These tokens, which support totp rfc, are especially useful when you need maximum security and stability.
