Token2 Pico FIDO2 Security Key review
A low-cost FIDO2 key with broad OS support, but no NFC, secure element, or attestation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Token2 Pico FIDO2 Security Key is a USB-A hardware security key for developers, FIDO enthusiasts, everyday secure logins, backups, and controlled deployment environments. It supports FIDO2/WebAuthn authentication through CTAP1 and CTAP2, along with U2F, PIN-based user verification, and physical user-presence confirmation. Its compatibility covers Windows, macOS, Linux, and Android. The key is based on the Raspberry Pi RP2350 microcontroller and includes preloaded, user-upgradeable firmware.
Pricing is straightforward: Token2 Pico costs $8.04 as a one-time purchase. The published plan includes FIDO2/WebAuthn authentication, a USB-A interface, upgradeable firmware, a physical user-presence button, and open-source management tools. Keyroost supports desktop management, while Libre Key Companion supports Android. Available management functions include FIDO2 credential listing, PIN management, and key reset. This makes the device relevant to buyers who want core authentication standards and basic administration without a recurring plan.
The main trade-off is its narrower hardware and deployment profile. USB-A limits connection options compared with keys that support NFC, and the product has no hardware secure element or attestation. The product page also states that it is intended for developers and FIDO enthusiasts and is not recommended for production use. Choose Token2 Pico when low upfront cost, standard FIDO capabilities, four operating systems, and open-source management are the priority. Buyers needing NFC, secure-element hardware, attestation, or a production-oriented security key should choose an alternative.
