Two-factor authentication — a combination of something you know (like a password) and something you have (like a smartphone or authentication token) provides much better security than passwords alone. And if SMS authentication is better than nothing, hardware authentication is even better.
Between the Yubikey 5C NFC, which can connect to your computers as well as your smartphones.

Simple and effective security
For me, this is the ultimate security key, providing simple and easy to use, yet effective protection.
The Yubikey 5C NFC is both a two-factor security key, multi-factor and passwordless authentication. It supports a wide range of protocols — FIDO2, U2F, smartcard, OTP, OpenPGP 3 — which means it offers robust security for both legacy and modern environments.
The advantage of the Yubikey 5C NFC is that it offers the best of all worlds.
In addition to all the cryptographic magic embedded in the key, the 5C NFC has both a USB-C connector and an NFC chip. This allows for wide compatibility since you get the convenience of both physical and wireless connection.
Wide compatibility
I use it on laptops and desktops (you can even use it on systems that only have USB-A ports), Android smartphones, and even my iPhone and iPad. Yes, you can use NFC on iPhone.

Everything is presented in a robust plastic shell, IP68 certified and shock resistant. Bonus, the key does not need batteries or recharging.
This one key works on everything I need.
€65 for an essential accessory
I’ve been carrying my Yubikey 5C NFC key fob for a while now, and it holds up well to the various vagaries of life that such items can encounter. It is still recommended to have a backup key in case your master key is lost, stolen or damaged. Note that you will need to register your second key the same way as the first, but some services do not support multiple keys.
This accessory may not be as shiny and exciting as a new smartphone, but it quickly becomes indispensable.
And for 65 euros, it is much more affordable than a new smartphone or a new laptop.
