A comprehensive password policy should include the following elements:
Password Complexity: Ensure passwords are a mix of upper and lower case letters, numbers, and special characters. Password Length: Require a minimum length, typically no less than 8 characters. Password Expiration: Mandate regular password changes, for example, every 90 days. Password History: Prevent users from reusing their previous passwords. Two-Factor Authentication (2FA): Add an extra layer of security by requiring a second form of verification.
