Authenticator app replacement
Token2 programmable tokens are a "drop-in" replacement of OTP mobile apps (such as Google Authenticator or similar). They can be used with authentication backends requiring TOTP tokens and are compatible with services generating the seed at the server side (and not allowing to import seeds)
Under your full control
Special apps, tools or scripts available under different platforms can be used to "burn" the secret hash seeds and configure other parameters. Some of the apps require an NFC module to operate.
