TrustKey T110

Overview

TrustKey T110 is a USB-A security key for passwordless sign-in and one-time-password authentication. It is best suited to people who want a single roaming key for several devices and services. Its broad protocol support is useful, but the USB-A connector and FIDO Security Level 1 certification are important trade-offs.

Key features

The T110 supports FIDO2, U2F, HOTP and TOTP, allowing it to cover several authentication methods in one device. The T Series supports up to 200 resident keys, which may suit people managing many passwordless credentials. PIN-and-touch access adds a physical confirmation step; the T Series uses a PKI-based touch mechanism, and the key has no biometric unlock.

TrustKey describes its keys as roaming authenticators, so one can be used with more than one user device. The maker also says its keys support Microsoft Azure AD sign-in on Azure-joined Windows PCs, including offline or airplane mode. Compatible services include 1Password, AWS, Cloudflare, Dropbox, GitHub, Microsoft, Google and NAVER, though compatibility depends on the service and setup.

The product comparison identifies the T110 as FIDO Security Level 1 certified and names KC, CE, FCC and RoHS certifications. TrustKey says its production complies with ISO 9001 and ISO 14001 standards. These credentials and marks offer useful context, but do not change the practical limits of the key's connector or certification level.

Platforms

TrustKey gives Windows and web as platforms, with Microsoft Azure AD sign-in support specifically described for Azure-joined Windows PCs. The T110 uses USB-A, so it is a less convenient fit for devices without that port unless the user has an appropriate adapter. The key's roaming design is useful for people who move between compatible devices.

Who it's for

The T110 is a sensible fit for users who want one hardware key for passwordless sign-in and HOTP or TOTP, especially those whose accounts and Windows setup match TrustKey's compatibility list. Its 200 resident-key capacity may also appeal to people with many credentials. It is less suitable for users who need biometric unlocking, a different connector, or a higher FIDO security level.

Pros and cons

• Pros: Supports FIDO2, U2F, HOTP and TOTP, reducing the need to choose separate keys for those protocols.
• Pros: Up to 200 resident keys in the T Series provides room for many passwordless credentials.
• Pros: Roaming use and Azure AD support on Azure-joined Windows PCs, including offline or airplane mode, suit users moving among compatible devices.
• Cons: USB-A limits direct connection to devices without that port.
• Cons: No biometric unlock; access relies on PIN and touch.
• Cons: FIDO Security Level 1 may not meet users seeking a different certification level.

Alternatives

Security Keys is the broader category to browse when comparing hardware keys. Choose Yubico Authenticator instead if you want free, open-source authenticator software and already have a YubiKey; it requires one to store credentials and generate codes. Deepnet SafeKey is another paid security-key family, with pricing by quote.

SafeNet MobilePASS+ is a paid alternative for readers looking at authentication software across mobile and desktop platforms. Swissbit iShield Key 2 offers USB-A or USB-C and NFC, with pricing through a sales partner. FEITIAN ePass FIDO-NFC Security Key is a more directly comparable option with USB-A or USB-C, NFC and FIDO2, U2F, HOTP and TOTP; its listed one-time price is 35.00 USD.

Solo 2 may suit readers who prioritize an openly licensed hardware and software design. Token2 T2F2-NFC-Slim is an alternative USB-A key with a listed product-page price of £18.80, excluding VAT, and volume pricing from two units. YubiKey 5 Series is worth considering if you want a USB-A model with NFC; its YubiKey 5 NFC plan is $58 per key.

Verdict

Choose TrustKey T110 if you want a USB-A roaming key that combines FIDO2, U2F, HOTP and TOTP, and your devices and services fit its compatibility. Its protocol range and resident-key capacity are the strongest reasons to choose it. Look elsewhere if you need USB-C or NFC, biometric unlocking, or a higher FIDO security level.
