FIDO Key Usage
Security keys have a glued plastic casing and aren’t indestructible. Unplug when not in use, especially before storing your laptop or phone. Avoid attaching directly to thick keyrings — use rope loops or thinner rings in between instead. Warranty doesn’t cover damage from improper use.Keyten Security Key is an NFC-enabled FIDO2 Security key. Having an NFC chip onboard allows using this FIDO2 key with modern iPhones natively, directly in the browser (starting from iOS 13.3) as well as Android devices with NFC. Keyten model features a capacitive sensor-type integrated touch-button. Keyten is only 6 mm thick.
Keyten is based on the original Token2 firmware, but without PIN complexity for simpler everyday use. Keyten does not have a serial number, so it is not intended for corporate users who require device tracking and centralized management - it is aimed at individual users.
FIDO security keys are small USB dongles that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards.
Keyten security key combines hardware-based authentication, public-key cryptography, TOTP/HOTP, U2F, and FIDO2 protocols to protect your accounts. This type of security devices provides the highest level of multifactor authentication of user accounts with Twitter, Facebook, Gmail, GitHub, Dropbox, Dashlane, Salesforce, Duo, Centrify and hundreds more HOTP, U2F, and FIDO2 compatible services. No additional tools or applications are required, and the login process is simple and reliable. Just insert the Security Key into a USB-A slot and authenticate with a simple touch. We also sell a compact USB-A to Type-C adapter, so you can use the same key with devices with USB-Type-C slots. The Keyten security key does not require a battery nor network connectivity - it is always on and accessible.
Keyten is based on FIDO® Alliance certified firmware

NFC Chip position
The NFC chip is located on the front/top side of the device (the USB metal connectors' side). While for good quality NFC reader devices (i.e. an iPhone), both sides would work with no issues, on devices with weaker NFC signal, touching the reader area with the top side of the key would give better results.
TOTP Feature
Keyten Security key can securely store the secrets for your TOTP profiles, but requires a companion app (available for Android and Windows) to generate the OTPs.iOS Support
Native support of NFC FIDO2 Keys in iPhone Safari

Understanding FIDO User Verification Modes and the always_uv Setting
Token2 R3.3 and later FIDO2 keys enforce user verification by default with always_uv = true, improving security, though some platforms and apps like Windows 10, macOS, and certain legacy clients may fail to handle this override correctly.

Introducing TOTPVault — self-hosted TOTP management for teams
Most TOTP apps work by distributing copies of the secret to every person who needs access — fine for personal accounts, but for shared service accounts it means MFA secrets scattered across people's phones with no clean way to revoke access when someone leaves.
