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

The page should explain length, uniqueness, reuse risk, and passphrase guidance.

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

Are passwords sent to a server?

The MVP should run entirely client-side and state that input is not sent.

Is complexity more important than length?

Length and uniqueness are usually more useful than simple symbol substitutions.
