Test patterns, not real passwords. Length and uniqueness usually matter more than predictable symbol swaps.

How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

The page should explain entropy, guessing speed, and why estimates are scenario-based.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

Should users enter real passwords?

No. The UI should tell users to test patterns, not sensitive real passwords.

Is crack time exact?

No. It is an estimate based on assumptions about attacker capability.
