Password policy tester

Run example passwords through a draft policy and see exactly which rule rejects each one, contradictions included.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Edit the policy or the examples, then press Test the policy.

Each verdict names the exact rule that rejected the password, so a contradictory policy shows itself as a good password failing for a bad reason. Character classes are ASCII only: uppercase, lowercase, digits, and anything else that is not a space counts as a symbol. The presets are starting points; every field stays editable.

Everything runs in this tab. The common-password list is a small built-in set of well-known picks, not a breach corpus. One run carries up to 200 examples of 200 characters each.

Runs on this device. Nothing is uploaded.
