Generate a password strength checker instantly, fairly, and privately. The controls and result are provided on one page so the task can be completed without an account or uploading the input.
When and why to use it
Use it for a quick local review of length, character variety, repetition, and obvious common patterns.
Example
Enter a proposed password and review the score and warnings before using it.
Step-by-step instructions

Type the password you want to assess; analysis stays in this browser.

Check the result, then copy, print, or export it only if it is suitable for your purpose.
How randomness and fairness work
The checker is deterministic. It applies the same local rules to the same input and does not send the password to a breach service.
Limitations
The estimate is heuristic, not a breach-database lookup or guarantee against cracking.
