Startup Idea: Automated Login Software for Multiple Accounts

Startup idea to develop a software that allows users to auto-login multiple accounts on various websites. The software should also be able to track login activities and days for each account.

Auto login for multiple sites without having to type anything.

I have multiple sites I manage and other sites that I assist on and am in need of software that would allow me to track my log ins and automatically log me in to all of my accounts and track days of log ins. I have to nshow activity on each account to retain getting my paycheck , if on auto-piliot it would be great.
