A strong password is one you can’t guess or crack using a brute force attack. Hackers use computers to try various combinations of letters, numbers, and symbols in search of the right password.
Overall, here are the main characteristics of a good, secure password:
Is at least 8 characters long. The longer your password is the better.
Uses uppercase and lowercase letters, numbers, and special symbols. Passwords that consist of mixed characters are harder to crack.
Doesn’t contain memorable keyboard paths.
Is not based on your personal information.
Password is unique for each account you have.
