The system told me that I should change my password, as it was 193 day old.

Why is that so?

I never had to change my password anywhere else.

Passwords are transmitted in a hashed format. If the hash is intercepted (and this is not spectacularly hard), free software exists to try and break it, thereby gaining access to your account. Easy passwords break very quickly but if your password is strong enough then it can take a very long time to crack it. Instituting mandatory password changes every 6 months means that if your password can actually hold that long then a hacker that has intercepted will have just wasted days/weeks/months on an obsolete code and they have to start all over again.

TLDR, lack of dealing with password changes means that you've never dealt with one of the simpler security protocols that a web/sysadmin might impose.
