Supported 2FA hardware

HelloID supports two types of 2FA hardware devices:

  • OATH Token: A low-cost OATH TOTP token. Provides one-time passwords for authenticating your end users to HelloID and other supported systems, usually via a LCD screen.

  • Security Key: A FIDO/U2F or FIDO2/WebAuthn security key, such as a YubiKey or Titan Security Key. Connects to your device via USB, Bluetooth, NFC, or other protocol to perform a cryptographic exchange.


HelloID supports all FIDO/U2F, FIDO2, and OATH devices. Below is a list of devices that have been tested and confirmed to work. But, any device that conforms to one of these standards should be compatible with HelloID.
