Turns out people have a difficult time remembering their Yahoo password. So Yahoo wants something that would protect people’s accounts better. Yahoo is building a two step authentication system where instead of logging in with a set password Yahoo sends you a four character password to your phone every time you want to log in. This would solve the problem of account holders using easy to remember but weak passwords. It would also take the stress out of creating and remembering passwords. Many different online services use this process and as cyber security becomes a bigger issue these kind of password generating services will continue to become more and more prevalent. It remains to be seen how quickly and widely technologies and systems that don’t rely on user generated passwords spread.
