I use my password manager to find unused accounts and delete them

This is a really bad title, but summarizes what I regularly do and recommend doing regularly. A nice side effect of using a password manager is, that it gives you a perfect overview about all your accounts. From time to time I go through this list (at the moment I have saved over 200 logins) and see if there are any services I no longer use and need. If this is the case I go to the website, log in and try to find the settings to delete that account.

For the Paranoids: Install Your Own Firefox Sync Server

Many people use Google Chrome, because they like it’s fancy syncing feature. You know, open a tab on your PC and just continue on your phone. Or because of the nice built-in password manager. Just save that damn password and it’s securely stored in your Google account and available everywhere. But what about privacy? You can forget it when you use Chrome. You have no privacy there. Google can read all of your browser history, passwords and bookmarks.
