A safe password today should

  • be at least 12 characters long, but the longer the better,
  • be as complex as possible, e.g. by including numbers, capital characters and special characters, and
  • only be used for one service.

There are a lot of services that require a password, and computers will always be better to remember a long and complex password than humans. Therefore, a password management software is highly recommended. Some free and open source password management systems are Bitwarden, Clipperz, KeePass, LessPass, Padlock or Passbolt.
