A 12-character all-lower-case password is stronger than an 8-character password of mixed lower and upper case, digits and symbols (26¹² > 95⁸). Length always beats complexity, and it's easier to type. #ActualSecurityAdvice
Better still use a password generator, e.g. I use KeePassXC (https://keepassxc.org/).
I store my password database on one cloud storage provider, my key file on a different cloud storage provider, and I use a strong master password.
My default password length is 32 AND I use a-z, A-Z, 0-9, and #$%^&”, etc. special characters…
