USB TypeC to Lightning adapter

Looking to use your FIDO2 type C key with your iPhone or iPad that don't have USB Type C ports? You'll need our FIDO2 type C to Lightning adapter to make it happen! This adapter is specifically designed to connect your FIDO2 USB TypeC key to your iPhone or iPad's Lightning port, enabling secure and convenient authentication for your iOS device. With its durable construction and easy-to-use design, our adapter ensures a seamless experience every time you need to authenticate with your FIDO2 key.

However, it's important to note that our FIDO2 type C to Lightning adapter is designed to support FIDO protocols only, and not OTP. If you need to use OTP functionality with your key, you will need to use NFC instead. Additionally, if you are using your FIDO2 key's HOTP functionality, please be aware that it uses keyboard emulation, which may interfere with the process of entering your PIN code on iOS devices. As the device recognizes the security key as a keyboard, it may disable the on-screen keyboard, making it impossible to enter your PIN code. To avoid this issue, we recommend that you either disable the OTP functionality of your security key using our Windows companion app, or unplug the key when entering your PIN code.

Additionally, there is another aspect that appears to be more of an iOS GUI glitch. When an iPhone prompts the user to choose the passkey type, users should start using the FIDO2 key without following the on-screen instructions.

Specifically, when selecting the "Security Key / External Security Key" option, iPhones only search for NFC keys and disregard the USB-connected ones.

We understand that security is a top priority for our customers, and we want to ensure that you have all the information you need to make an informed purchase. If you have any questions or concerns about our adapter or your FIDO2 key, please don't hesitate to contact us.

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.

Android, NFC, and the Missing Piece of WebAuthn

For years, Android users have faced a frustrating limitation—Android does not support CTAP2 over NFC. This means no PIN verification and no discoverable credentials (passkeys) when using NFC, and therefore limited to simple U2F-style flows without user verification. That said, there finally seems to be a solution.
