What Makes a Password Strong?
Length Matters
Longer passwords are exponentially harder to crack. Aim for at least 12 characters.
Complexity is Key
Use a mix of uppercase, lowercase, numbers, and symbols to increase complexity.
Avoid Patterns
Common words, sequences, or keyboard patterns are vulnerable to dictionary attacks.
Uniqueness
Never reuse passwords across different services to prevent credential stuffing attacks.
