Tpass

blockchain two factor authentication based on private keys instead of passwords

This is just a short description, if you want to read more go to our github
TPass lets you move from old rusty passwords. All you need is just two private keys stored in a secure storage on any device such as computer, smartphone, smartwatch or hardware token. You don’t need to trust 3rd party solutions. And you’ll know about every attempt of login and you will be able to easily revoke authorization and change private keys if something goes wrong.

Why blockchain

You don’t need to trust any 3 party service, like you do using password manager services
You only send a blockchain message signed with a private keys so there is no possibility of man in the middle attack
You gonna know about every attempt of login and every valid authorization. It’s stored on blockchain.
If someone steal one or your private keys, you can easily revoke all authorizations, and change stolen key
If you lose one of private keys, you will be able to recover it with the second private key you have
