We are open sourcing a few tools we developed recently. Here is the second one.
Install it from chrome webstore Here are the docs
A completely client side password generator.
What is it
Its a chrome app to generate unique passwords for each site. Depending upon the domain and a master password a unique password is generated. It doesn’t need any server and everything happens on the client side.
I want to use a unique password for each website. However, I don’t want to use lastpass/1password as I find their interface confusing and overkill, and I don’t want my password stored on remote servers.
I use a simple passwording scheme. I have one master password. For each site, I append the first two letters of the domain to master password and use that as the site password. This is sub-optimal as its easy to understand this scheme, if say two of my passwords are leaked.
I want to algorithmically generate the password on the client side, with a chrome app.
How does it work?
password_1 = SHA256(masterpassword+domain) password = take_first_8_letters(password_1)
This will generate a per domain password with 8 characters of entropy and it depends only on master password and the domain.
In the UI side, it works like this:
- You set your master password in the app.
- You click the Chrome app button to generate a domain specific password. It generates the domain specific password and copies the password to clipboard.
- You use the password to signup. Next time you want to login, you click the app to get the password.
