Pros and cons
SoloKeys Solo 2
Pros
- Open source is a yes, so the hardware design and firmware of the Solo can be reviewed by anyone.
- Protocol support covers fido2, u2f and piv, so the same token handles modern web sign-in, legacy sites and PIV workplace logins.
- Connectors are usb a and usb c, covering the port shapes found on current desktops and laptops.
Cons
- Biometric unlock is a no, so unlocking rests on a PIN typed on the key rather than a fingerprint check.
- Support runs on email, help centre and community, with no phone line or live chat listed for a stuck setup.
- There is no free plan, and at $35 the Solo sits in the budget class, so a light user still pays the full device price.
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
SoloKeys Solo 2
Who it suits
- Readers who want open source hardware they can inspect before buying.
- People who want the same key on desktop and phone, given support for Windows, macOS and Linux.
- Anyone happy to unlock with a PIN instead of a fingerprint, since biometric unlock is a no.
Who should look elsewhere
- Google Titan Security Key, if you want a fingerprint unlock, because biometric unlock is a no here.
- Thetis, if the $24.99 to $49.99 range fits your budget better for a spare key at a desk.
- Token2, if you want to weigh a lower entry point, where prices run €7 to €37.
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
SoloKeys Solo 2
How much does the SoloKeys Solo cost?+
The Solo is a hardware key sold at $35, and the entry price is listed as $35. That figure covers the device itself, so there is no subscription to renew and no second bill later. Budget for the key, then buy a spare if you want a token waiting at another desk.
Is there a free version or trial of the SoloKeys Solo?+
There is no free plan, so a key has to be bought to get started. The Solo is listed as budget here, which is the budget class rather than a premium tier. It is a straightforward token rather than a service, so there is nothing to remember or cancel later either.
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.
