zpass3 solves the problem of having to memorize multiple complex passwords for all kinds of sites and applications.
Your passwords are never stored anywhere. All you need is your master secret. There no need to trust on a password provider security practices or their relations to authorities.
You can download the code and run it locally. All you need to recall your secrets is the code that will recreate them for you.
People rely more then ever on cloud services to keep their personal and work data. Password authentication is the standard for all of these online services. These passwords need to be strong to keep up with the increase of computational power, requiring users to create unique complex passwords for each service they use and memorize all of them. This is an hassle to the user. zpass3 makes it easy to create strong passwords without the need for the user to remember more then one strong password.
zpass3 uses modern cryptography to combine your master password with an identifier of the website or app you want to login into and outputs a password. Given the same combination of master password and identifier zpass3 will output the same password.
The cryptographic function used by zpass3 is called SCrypt and is used to secure all kinds of applications inclusive in Crypto Currency. This function is not reversible. That means that even if an attacker would get access to one password and an identifier they would not be able to recover your original master password.
