Weak passwords are one of the most common security vulnerabilities. Using strong, unique passwords for each account is essential for protecting your personal information and preventing unauthorized access.
What Makes a Password Strong?
- Length: At least 12 characters, preferably 16+
- Complexity: Mix of uppercase, lowercase, numbers, and symbols
- Randomness: No dictionary words or personal information
- Uniqueness: Different password for each account
