What Makes a Password Strong?
A strong password has these characteristics:
- Length — at least 12 characters (16+ is even better)
- Complexity — mix of uppercase, lowercase, numbers, and symbols
- Uniqueness — different password for every account
- Randomness — no dictionary words, names, or dates
Common Password Mistakes
Avoid these common mistakes:
- Using personal information — birthdays, pet names, phone numbers
- Simple patterns — “123456”, “password”, “qwerty”
- Reusing passwords — if one account is breached, all are compromised
