We founded Tozny, a Galois spin-off company, to solve the password conundrum. Your phone is the key: Easier and more secure than passwords, Tozny replaces passwords with an easy-to-use cryptographic key on your mobile phone.
Passwords are past their prime. Users are buried under the weight of too many passwords, and most of us constantly struggle with these password conundrums: Simple passwords are easy to guess, but complex passwords are hard to remember. Writing passwords down means not having to remember them, but it also means they might get stolen. Sharing passwords between accounts means that if one account has a password database spill, all the accounts are compromised.
