Password requirements vary widely depending on the system, website, or application setting the rules. However, I can provide a summary of common practices and recommendations:
  • Length: Typically, a minimum length of 8 characters is recommended, but many systems now require 12 characters or more. Longer passwords are generally more secure.
  • Digits: Many systems require at least one or more numerical digits (0-9).
  • Special Characters: A special character requirement often includes symbols such as ! @ # $ % ^ & * ( ) _ + - = [ ] { } \ | ; : ' " , < . > / ?.
  • Uppercase Letters: Most systems require at least one or more uppercase letters (A-Z).

General Recommendations:

  • Complexity: Aim for a mix of uppercase and lowercase letters, numbers, and special characters.
  • Avoid Personal Information: Do not use easily guessable information such as your name, birthday, or pet's name.
  • Password Managers: Consider using a password manager to generate and store strong, unique passwords for each of your accounts.
  • Two-Factor Authentication (2FA): Whenever possible, enable 2FA for an added layer of security.
