@feditips I have had enormous success with YubiKey. I am not affiliated in any way with them
They offer FIDO U2F compliant keys with a lot of features. My primary keys are 5C NFC and work with my Phone and Macbook. The greatness of what YubiKey created is that the key itself is where the info is stored, not the app like Google/MS. Using my pw-manager (Bitwarden) to store the QR codes allows me to recreate a key if I loose mine, or create a backup key. https://www.yubico.com/
