Pros and cons
OnlyKey
Pros
- Open source firmware, paired with a logging policy in which the company states it holds no customer keys or sensitive data.
- The Duo carries usb a and usb c in the same unit, so machines with either port are covered by the same purchase.
- It speaks fido2, u2f and otp and also handles totp codes, so the same key covers security keys, authenticator codes and passwords.
Cons
- Biometric unlock is no, which leaves the PIN and its wipe rule carrying the security of the device.
- The free plan is no, so the only route to the features is buying hardware at €49.95.
- The price runs above Token2 at €7 to €37 and the Google Titan Security Key at $30 to $35.
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.
Who each suits
OnlyKey
Who it suits
- People who want a physical key for passkeys and authenticator codes and who treat open source firmware as a requirement rather than a bonus.
- Mixed-port desks that need USB-C and USB-A covered by usb a and usb c in a single purchase.
- Buyers who would rather own the key outright and can accept a PIN instead of biometric unlock.
Who should look elsewhere
- Not for the tightest budget, since Token2 runs €7 to €37 against OnlyKey at €49.95.
- Not for people who expect to pick up a phone, because OnlyKey lists email, help centre and community as its support routes.
Token2
Who it suits
- People who want passkey and two-factor login backed by hardware they own.
- Teams that need one key type for sites, apps and PIV card readers.
- Shoppers who compare price first and find Token2 the cheapest way in.
Who should look elsewhere
- Buyers who want open firmware, which SoloKeys Solo 2 at $35 suits better.
- Shoppers who want a fixed dollar price, since Token2 lists euro figures while Thetis lists $24.99 to $49.99.
- People who need a biometric on every model, as biometric unlock is not standard across the range.

Questions about each
OnlyKey
What does an OnlyKey cost, and what do rivals charge?+
The Duo is priced at €49.95, and entry prices start at €49.95. The figure buys the hardware, so the outlay at entry is the outlay later on, and the device price is the only price on offer here. Cheaper rivals exist: Token2 runs €7 to €37 and the Google Titan Security Key runs $30 to $35.
Which protocols and passkey methods does it support?+
The protocol list is fido2, u2f and otp, and passkeys are supported as well. That lets the same device act as a passkey authenticator, a security key for a login prompt and an OTP token for codes. Password storage sits on the key too, so a login, a code and a saved credential are handled by the same purchase rather than by separate tools.
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.
