Get a password manager and change your life.
I don’t even know my passwords anymore. Just the main one - which I tell to nobody. Use Ben Franklin’s aphorism, “Three can keep a secret if two of them are dead”
I’ve been using Norton Security’s Identity Safe for at least 5 years. However I have refrained from using the cloud option so far. I want to keep my PW’s on my PC.
I’m inclined to believe the theory that “if it’s in the cloud, is it really yours?”
I use a pw manager and it is great.
