This is ONLY a recommendation as I am NOT affiliated with either company but I am in the IT world and you should be using something like Roboform Everywhere or LastPass. Just get the trial to start and then wait until they run a special and then get the multi-year subscription for a huge discount. I have been using Roboform Everywhere for 15 years and recommend it to everyone I know.
One last thing: a LONG password is much better than a complex password that you change often. Changing a PW often means it is easier to forget. Use one of the software programs I mentioned above and every web page, app, forum, bank, etc will have a long unique password.
