How to use this tool
Enter a candidate to update the score and suggestions. The show-password option reveals the original text, so explore the scoring behaviour with an example before using a sensitive value.
Results and examples
Adding length or character categories may change the score. A result of 80 does not mean eighty-percent safety, establish whether the password has leaked or predict a definite cracking time.
Limitations
- The score is a local heuristic, not a breach-database lookup or a full guessing-attack model.
- Reuse, phishing and account-recovery weaknesses cannot be assessed from the string alone.
