• Powered by PIN+ firmware – open source, FIDO Level 2 certified, and verifiable

Biometrics: Convenience First, Not More Security

It’s important to clarify: biometrics do not enhance the cryptographic security of a FIDO2 key. The core protection remains the same, whether you use a PIN or a fingerprint.

Instead of entering a complex PIN, you simply swipe a registered finger. This provides faster access, especially in high-frequency usage scenarios and reduces friction in strong authentication workflows. With Bio3, we bring that convenience to a secure hardware key – now with cross-device and mobile support.

Durable Protection for Enhanced Longevity

The key includes a specially designed leather protective case that shields the fingerprint sensor from physical damage and everyday wear. Biometric sensors, especially those exposed on the surface, are susceptible to accidental impacts, scratches, and contamination from dirt, dust, or moisture. This durable case serves as a barrier that minimizes the risk of sensor damage during regular use or transport. By preventing direct exposure to harsh conditions, it helps preserve the sensor’s responsiveness and accuracy over time, ensuring consistent and long-lasting reliability for your biometric security key. The protective case is included in the package at no extra cost.

iPhone Fingerprint Management – A Market First

The Token2 Bio3 is the first biometric FIDO2 key that supports fingerprint management directly on iPhones.

Our latest iOS companion app (v2.3) will allow you to:

• Add or remove fingerprints
• View enrolled slots
• Fully manage biometric templates – without needing a PC

Powered by Token2 PIN+ Firmware

At the heart of Bio3 is Token2 PIN+, our secure, feature-rich firmware that is:

• Publicly audited
• Open-source
• FIDO2 Level 2 certified
• Used across our trusted FIDO2 PIN+ product lineup
• Stores up to 300 passkeys — the market's leading capacity.

Who Is Bio3 For?

• Security-conscious individuals and professionals
• Enterprises deploying phishing-resistant MFA
