MicroOTP - A Micropython One-Time Password Generator

====================================================

Do you use OTPs ? OTPs are good!

OTPs are a great way to protect your data from phishing and social engineering.

But what if you want to protect with a 2FA a mobile app?

Do you see yourself the roundtrip? So MicroOTP comes in handy.

Also, how precious is the data you are going to access?

Sometimes you need a place safe than a smartphone to store your One Time Passwords.

Google Authenticator is a great tool, but if you really go in paranoid mode, the smartphone is itself insecure.

Project aim is to provide a banking grade security, long-lasting, OTP generators, that easy fit in your pocket,

with schematics and everything you need to build it by yourself.

It comes with a client-side only implementation of RFC 4226 (HOTP: An HMAC-Based One-Time Password Algorithm)

and RFC 6238 (TOTP: Time-Based One-Time Password Algorithm).
