Frequently asked questions

Is this a guarantee of security?+

No meter can guarantee safety. Prefer long unique passwords and a password manager.

Do you send my password anywhere?+

No. Strength checks run only in your browser.

Why does a long passphrase score higher than a short complex password?+

Length multiplies the search space faster than adding a few symbols. ToolVera’s strength check rewards longer unique phrases even when they use mostly letters.

Does a strong score mean my password is not in breach lists?+

No. Strength estimates entropy from structure; it does not look up leaked passwords. Use unique passwords per site and a manager even when the meter looks green.
