Okay i Make a Extension which will works as a password generator and manager(works like that though) . There are three main things we need to login username website and password and we all forget are password so i make a extesnion which generate password using the username and website name. An dit generates same password for same username and website every time so it works like the password manager .I f u use it there is high chance that anyone less can use it to know ur password if he had the username so i recommend u to make a secret key yourself dont tell anyone and just write it after the username so it will be secret for everyone.
