Feitian OTP C100 (HOTP hardware token)

Overview

The Feitian C100 is a compact one-button hardware token that generates a 6-digit event-based one-time password (HOTP). Each button press advances the counter and displays a new code. It is built to OATH HOTP standards for organisations that prefer physical tokens over mobile authenticators.

Key specifications

• Type: HOTP (event-based / counter-based)

• Operation: single button

• Display: 6-digit OTP

• Form factor: compact hardware token

• Secret key / seed: provided after order via the seed request process (see leaflet and FAQ)

Compatibility notes

Choose C100 when your identity platform enrols OATH HOTP hardware tokens. If your platform requires time-based TOTP (for example many Entra OATH hardware token setups), order the C200 instead.
