A password is a secret combination of characters, typically used to authenticate and verify the identity of a user accessing a computer system, online account, or digital device. It serves as a security measure to prevent unauthorized access and protect sensitive information. Passwords are usually created by the user and should be kept confidential and not shared with others.
Good passwords include a combination of letters (both uppercase and lowercase), numbers, and special characters. Longer passwords with a combination of these characters are generally considered more secure. It is important to choose strong, unique passwords and regularly update them to enhance the security of your accounts and protect your personal data.
