At last!!!

Really thrilled to have such a simple authenticator app with the deep power of the blockchain behind it. This is the long-overdue beginning of real Internet security for everyday consumers.

Now everybody drum on your favorite applications, telling them to integrate Hydro Raindrop, so we can have a rich yet safe Internet, for the very first time!

Hydro - 1$

I have my Crypto tracking app set to go off once HYDRO token hits 1$. I might need to wait a few years but I know the day will come. Buy HYDRO, spread the good word.
