Pros and cons
SoloKeys
Pros
- Hardware and firmware designs stay open for public review and audit
- Passkeys remain on the key instead of uploading to cloud storage
- Firmware updates extend protection without requiring frequent replacement
Cons
- Use depends on websites adopting supported passkey authentication standards
- Contactless approval appears only on the upgraded NFC variant
Token2
Pros
- Fees of €7 to €37 start below Thetis at $24.99 to $49.99 and Google Titan Security Key at $30 to $35.
- The full connector set of usb a, usb c and nfc covers laptops and phones with the same key.
- Protocol support spans fido2, u2f and otp, so one device handles sites, apps and smartcard or card-reader logins.
Cons
- The firmware is closed source, so the code inside the key cannot be inspected by buyers.
- Biometric unlock is not universal across the lineup, so some models rely on a PIN alone.
- Prices are listed in euro rather than dollars, unlike SoloKeys Solo 2 at $35 and Thetis at $24.99 to $49.99.

Questions about each
SoloKeys
What does SoloKeys sell?+
SoloKeys sells Solo 2 devices that enable passkey authentication for supported online accounts. The range includes USB A and USB C models plus a variant with contactless approval for supported phones and tablets. A Hacker edition also serves developers who want to experiment with custom firmware and applications.
How do passkeys work with Solo 2?+
Insert the key into a USB port and wait for the service prompt during login. Touch the capacitive sensor on the key to confirm presence and complete authentication. The process replaces typed passwords and one time codes on services that support the standard.
Token2
How much does a Token2 security key cost?+
Hardware fees run €7 to €37 for the range. That is a one-off purchase, and there is no renewal or subscription attached to the key itself. Prices are listed in euro, which matters if you are comparing against a dollar figure elsewhere. The free browser tools stay free either way, so you can try the login flow before buying hardware.
Is a Token2 key cheaper than a Thetis key?+
Yes. Token2 lists fees of €7 to €37 while Thetis lists $24.99 to $49.99, so Token2 sits lower at both the cheapest and the dearest end. Both cover FIDO2, so the comparison comes down to price, connectors and any extra protocol support you need. Nothing about the purchase changes over time on either side.
