Password or passphrase?
Random character passwords are compact and work well with password managers. Passphrases can be easier to type and remember but need enough independently selected words.
Entropy estimate
The estimate assumes uniform random selection from the displayed character set or built-in word list. It is not a prediction of an attacker’s actual cracking time.
Safe storage
Use a reputable password manager and a different password for every account. Enable multifactor authentication where available.
