Password manager with checking for expired logins and passwords

"I find this a bit confusing. I can't imagine why you'd want to do this. Is it to clean up your list of credentials? Is it to make sure your username will not be taken by someone else? If you want to login to a site and find out that you can't, you can probably register again.

Also, I'm not sure why you want this application to log out. It would be easier if it would simply let the session expire.

Anyway, the password manager called Clipperz (it's an online service that also executes in the browser) allows the user to create links to automatically login to web sites. You could open this links (there must be a Firefox addon that allows to open multiple links simultaneously) and check that the web page is open and the user is logged in.

As mentioned in the previous answer, the implementation varies, so it takes some manual work to create the login links."
