Frequently Asked Questions
What makes a password strong?
A strong password is at least 12 characters long, includes uppercase and lowercase letters, numbers, and special characters, and is not a common or dictionary word.
How does crack time estimation work?
Crack time is estimated based on password length and character variety. Longer passwords with mixed character types take exponentially longer to crack through brute force attacks.
What are the most common passwords?
Common passwords like "password", "123456", and "qwerty" are checked instantly. If your password is on the common list, it can be cracked in seconds regardless of length.
