Frequently Asked Questions
How is crack time estimated?
Based on the number of possible combinations divided by an assumed guesses-per-second for modern hardware. An estimate — actual crack time depends on attack method and available hardware.
What makes a password truly strong?
Length first — every character multiplies combinations. Then character variety. Then avoiding words, names, dates and patterns. A 20-character random string is exponentially harder than 10 characters.
Is "P@ssw0rd" strong?
No — extremely weak. It is a well-known leet-speak substitution. Appears in every cracking dictionary. Hackers try these patterns first.
Most commonly hacked passwords?
123456, password, 123456789, qwerty, abc123. Billions of accounts use these. Never use any of them.
Does checking here expose my password?
No — the check runs in JavaScript in your browser. Your password is never sent to any server.
