Our verdict on each
Token2
Token2 builds physical security keys and display tokens for passwordless and one time code login instead of app based authentication. It suits teams and individuals who want phishing resistant hardware with self loaded seeds, standalone operation, biometric options and broad protocol support.
OnlyKey
OnlyKey suits buyers who want a hardware key that handles passkeys, TOTP codes and password storage together, with open source firmware and a logging policy that keeps customer secrets off the vendor's side. The Duo costs €49.95 as a device, above Token2 and the Google Titan Security Key.

Pros and cons
Token2
Pros
- Sells biometric FIDO2 keys for strong phishing resistant authentication
- Offers battery powered display tokens that work without phones or apps
- Supports programmable seeds through burner tools for full user control
Cons
- Physical hardware requires carrying keys and managing PINs and codes
- Advanced models add complexity around setup and seed programming
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.
Who each suits
Token2
Who it suits
- Teams adopting passwordless login for shared accounts
- Individuals who prefer standalone tokens over phone apps
Who should look elsewhere
- People who want software only authentication without hardware
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.
Questions about each
Token2
What does Token2 sell?+
Token2 sells physical security keys and hardware tokens for passwordless login and one time codes. The range includes FIDO2 keys, display tokens and models that combine several authentication protocols. Display versions generate codes directly on the device.
What are programmable OTP tokens?+
Programmable OTP tokens let holders load their own seeds with burner tools. They run on battery power and operate as standalone hardware, so no phone, app or cloud connection is required. The design gives users direct control over stored secrets.
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.
