Offsync is a stateless open-source password manager inspired from Lesspass

OffSync

OffSync is a simple open-source stateless password manager inspired by LessPass.
The significant difference is that it allows users to store profiles (site, username, password length, etc.) locally without creating an account. So, no bloated web and online accounts.

What does stateless actually mean?

Stateless simply means that your password is never being stored. You just store some information about your account locally. And, Passwords get generated on the fly depending on the account info you provided and the secret key. There is no master password. Every secret key is master password. Didn't understand, check out yourself here.

How this works?

OffSync asks you four simple questions site, username / e-mail, length, counter.

Counter is just an integer which has a default value of 1. counter can be used to change the password of any profile that you saved before. For instance, if you have a GitHub account and after some time you want to change its password without changing the basic parameters like site, username/e-mail, length then you can change the value of counter may be like 2.

Concept Description

1. Create a salt: site + username / e-mail + length + counter
2. Create a seed from KDF: KDF(salt, master password)
3. Seed the PRNG to generate a strong password
