What makes a password secure?
A secure password is a defense mechanism protecting your personal information, financial data, and digital identities. Security experts recommend passwords that are long, contain a mix of uppercase/lowercase letters, numbers, and symbols, and are unique to each account.
Understanding Password Entropy
Entropy measures the randomness of a password in bits. Higher entropy means a password is mathematically harder to guess. Every additional character increases the entropy exponentially, which is why length is the single most important factor in password security.
