About Secure Passwords

A strong password acts as the primary defense against unauthorized access to your accounts. It should be at least 12-16 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols. Randomly generated passwords are significantly more resilient against dictionary and brute-force attacks than human-created ones, which often rely on predictable patterns, words, or personal information.
