Password complexity matters.
Don't use passwords that are easy to remember.

Use a password manager to automatically create long-phrase or complex passwords like:
catdogBadgerjumpThunderMonkeyTranscendGuitarRampant
or
91JkOunJ1%8na(10pNhHu1*5mn_rseTm
This minimizes your risk of dictionary attacks, even with long-phrase common words. The random and long nature is hard to crack.

Completely agree. Diceware is the best method. So make it strong and then find a manager you trust. I'd recommend KeepassXC
