Famous for drastic security and the limitations imposed on the operating systems iOS yes macOS, Apple didn't really give importance to passwords of "Users & Groups” on Mac operating systems.
Up to MacOS High Sierra, Mac owners could opt for a simple one-character password. Starting with macOS Mojave, Apple requires that the password contain at least 4 characters.
From a security point of view, a password as strong as possible is welcome. A strong password (strong password) can prevent unauthorized persons from accessing our account. In addition, the system password is required at key points, such as installing an application, changing security settings, and accessing Keychain (a utility that stores passwords and accounts).
