There is an occasion to change the password.
In general, I really do not like this statistics. I want to communicate peacefully in the forum and not be afraid that my confidential data will be stolen
It is good to change your password if you hear a news about any major hacks and one thing you have to be careful is that ,never to use the same password for all the websites you are using and it might hurt you,i do keep a different password in every website i visit and try to have a different username and if i see a hack news i would change my password to avoid those leaks.
