I have more than 800 online accounts, but I know exactly one password: the key to my password manager.I use the internet professionally; you might not have quite as many accounts to manage. Nevertheless, the idea of moving dozens, if not hundreds, of passwords into a password manager and then changing them all to make them stronger sounds enormously daunting to many people.But there’s good news: Getting started with a password manager is simple, and all password managers have tools to make capturing and improving your passwords easy.
