Frequently asked questions
Is it safe to type my real password into this tool?
The check runs entirely in your browser and nothing is sent to a server. That said, as a general precaution, many people prefer testing a similar but not identical password out of habit.
What does the tool check for?
It looks at length, character variety (uppercase, lowercase, numbers, symbols), and common weak or predictable patterns to estimate strength.
Does it check if my password has been leaked in a data breach?
No, this tool only evaluates the structural strength of the password itself; it does not check breach databases.
Why did my password get a lower rating than expected?
Common patterns like sequential characters, repeated characters, or short length can lower the strength rating even if the password looks complex at a glance.
