is it that much of an inconvenience to you to remember 3 passwords in total?

well my suggestion to you is just put it 1 number off, or capitalize a letter that way you wont have to remember a whole new one but rather just 1 difference.

I myself think its good that the passwords all are forced to be changed ever 90 days or whatever, it keeps all the accounts safer. Also its just good in general to change passwords ever once and a while. A word of advice dont have the same password for everything because if it is compromised so is everything else.
