The OTP Burner app from Microcosm allows you to reprogram OTP cards and tokens with new settings including seed (secret key) and timestep values. You can burn a new secret key directly by scanning a QR Code or you can configure the settings manually. This app enables you to deploy hardware OTP tokens as a drop-in replacement for software authenticator apps in OATH-compatible two-factor (2FA) and multi-factor authentication (MFA) logins. You can replace apps like Microsoft Authenticator and Google Authenticator with hardware OATH tokens, meaning your users do not need a smartphone to perform 2FA/MFA. Compatible with Google, Facebook, Azure AD MFA, Office 365 and many other platforms. This app supports the following programmable TOTP tokens from Microcosm: Feitian c200 (I34 NFC) Fetian TOTP Card (VC-N200E) c200m These can all be found online here: https://www.microcosm.com/it-security-hardware/oath-otp-authentication-tokens This app uses NFC.
