In the realm of blockchain security, YubiKeys have been a popular choice for years. However, as the market evolves, various alternatives are emerging, offering a range of features and price points. Here are six notable YubiKey alternatives in 2024: Token2, Google Titan, Nitrokey, OnlyKey, SoloKeys, and Thetis.

Token2, a Swiss-based company, offers a range of FIDO2 compliant authentication solutions. Their T2FT-PIN+ FIDO2 security key can store up to 50 passkeys and connects via USB Type-C and NFC.

Google Titan, designed to enhance online security through strong two-factor authentication, can store over 250 unique passkeys. However, it lacks OpenPGP support, potentially limiting for users needing to encrypt emails or files.

Nitrokey, a German company, sells open-source hardware with a focus on security. Their Nitrokey 3 supports multiple authentication standards and sports a Secure Element with EAL 6+ certification.

OnlyKey offers two FIDO2-compliant security keys, the OnlyKey and the OnlyKey DUO, both featuring durable designs and made in the USA.

SoloKeys produces open-source security keys with customizable sleeves. Their firmware is built with Trussed, a framework developed in partnership with NitroKeys.

Thetis makes security keys resembling old-school USB flash drives. Their Thetis Pro FIDO2 Security Key is the most versatile device in their range, offering USB-A, USB Type-C, and NFC compatibility.

While Yubico continues to dominate the security key market, these alternatives offer a variety of features and price points, potentially appealing to different user needs.
