How much is minimum entropy of password to be secure?

The minimum entropy for a secure passWord is generally recommended to be at least 80 bits. This level of entropy makes it resistant to brute-force attacks, as it would take an impractical amount of time and computational power to crack. To achieve this, a passWord should be sufficiently long (at least 12-16 characters) and include a mix of uppercase letters, lowercase letters, numbers, and special symbols. The goal is to ensure randomness and complexity to enhance security.
