What is a Complex Password?

A complex password is designed to be difficult for unauthorized users to guess or crack. It often adheres to the following criteria:

• Length: At least 8-12 characters long.
• Variety: Uses a mix of different types of characters (uppercase letters, lowercase letters, numbers, and special characters like !, @, #, etc.).
• Unpredictability: Avoids common words, phrases, or patterns like "password," "123456," or "qwerty."
• Uniqueness: Unique for each account to prevent a security breach in one account from compromising others.
