Review on Enhanced Security with OnlyKey FIDO2/U2F Key: Hardware Password Manager, Two Factor Authentication, Portable Encryption, PGP/SSH/Yubikey OTP Support, Windows/Linux/Mac OS/Android Compatible by Farhad Cantu

You need this little device. You may not know it yet, but you definitely need it. Personally, I've found my credit card information twice on hacking sites (google your credit card numbers if you dare. It's awful) and people have repeatedly attempted to hack into my various accounts. The old "security is the password” paradigm is dead, and we are already paying the price for not giving it up. OnlyKey Color enables various forms of two-factor authentication, making account hacking nearly impossible. And unlike SMS messages (which can be intercepted, or your phone can be stolen or cloned to get them, or a criminal can just call your phone company and use social engineering to "become" you), or 2FA- Codes used by applications such as Google Authenticator (which can be easily intercepted, and authenticator data can even be cloned by malware), OnlyKey Color has its own hardware number pad outside the computer that cannot be read or intercepted by malware. This is the safest design possible for this purpose. In addition, OnlyKey Color stores up to 24 URLs, usernames and passwords for your favorite websites in a way that is seemingly impossible to extract from the key. And without your PIN (up to 10 digits, self-destruct after 10 failed attempts) it doesn't matter if someone else has access to the key - they can't use it and can't change it. However, the setup takes a little time. But at least I didn't find it difficult or confusing. I had to reprogram information on several websites to increase the delay between entering a URL and entering a username/password simply because websites are sometimes slow to load. My only complaint is that the URL field is too small (56 characters I think) for many banking and similar websites whose login pages can have absurdly long URLs.
