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.
