Startup Idea: Unified Interface for Password and Task Management

Startup idea to develop a software that provides a graphical interface, likely as a browser extension, which allows users to manage their online tasks and store passwords. This would help users who sign up to multiple sites and services, manage their tasks, and ease access by securely storing their passwords.

I am currently unemployed and searching for a part time job while I attempt to get my own business up and running. To pay for the bills I've been trying to do a bunch on online mTurk tasks and transcription services. At the end of the day there are too many sites and services I signed up for, and the passwords for them also. I find myself remembering a site and not being able to log in and wasting time resetting passwords all the time. If there was a graphical interface compatible with my computer or my Chrome browser that could keep track of multiple sites and their information. Compiling said info into something that I could actually see.
