Nitrokey 3 vs Token2 PIN+Bio3

Nitrokey 3 is a physical security key for two-factor and passwordless authentication, private-key storage, and password management. Sign-in can use a PIN and a touch of the device’s button; FIDO2 and U2F work over USB and NFC, with FIDO2 also covering passwordless and SSH login. OpenPGP Card and S/MIME store private keys for asymmetric cryptography and email encryption, while PIV supports smartcard use. These functions are listed with secure element support. The SE050M secure element is Common Criteria EAL 6+ certified up to the OS level. Password Safe holds up to 50 entries, each with login, password, comment, and OTP fields. Nitrokey says its hardware and software are open source. The key stores cryptographic keys and certificates, not ordinary files. It works with current browsers and is managed using Nitrokey App 2 or nitropy. Listed systems include Windows, macOS, Linux, BSD, Android, and iOS, though mobile support is described as partial in the FAQ. Pricing starts from €32.
