Twitter informed over 336 mln of users that they should change their password. Though there is not direct threat as they say, you should change the password just for good measure.
Security and privacy as we know from recent events concerning facebook and the company which used the gathered data — Cambridge Analytica is very important. Mainly because most of people is using the same password for many services. Why? Because it’s convenient. And let’s be honest, we are using same password.
Even if there is no direct threat, you should remember to change your password from time to time. In ideal situation it should be changed at least once in three months but of course we are doing no such thing.
