    What makes a password strong?
    Length (12+ characters), mixed case, numbers, symbols, and avoiding dictionary words or predictable patterns.
    Should I reuse strong passwords across sites?

    Is a longer password always better?
    Generally yes — length is one of the strongest factors against brute-force attacks.
