Why Strong Passwords Matter
Weak or reused passwords are a primary target for hackers. Using complex, unique passwords for different accounts significantly reduces your risk of data breaches and identity theft.
Tips for Creating Strong Passwords:
- Use a mix of uppercase letters, lowercase letters, numbers, and symbols.
- Aim for longer passwords; length adds significant strength.
- Avoid common words, dictionary terms, names, dates, or easily guessable information.
- Consider using a passphrase (a sequence of random words).
- Use a password manager to generate and store unique, complex passwords for each account.
