Password Security Audit
Password Strength Checker scores a password against five structural checks — length of at least six characters, length of at least twelve, an uppercase letter, a digit and a symbol — and labels the result from extremely weak to military hardened.
How to use Password Security Audit
- Type or paste the password into the field.
- The score and label appear as you type.
- Read which of the five checks you are missing and adjust.
Where Password Security Audit is useful
- Sanity-checking a new password before saving it.
- Showing why a short password with a symbol still scores badly.
- Checking that a passphrase you already use meets a service's rules.
Formats, algorithms and limits
The score is a five-point structural checklist, not a crack-time estimate: it does not model dictionary attacks, breach databases or pattern frequency. A password can score five and still be weak if it is a known phrase. Nothing you type is stored, hashed or sent anywhere — the checks run in the page.
Troubleshooting and honest limits
- Length beats complexity: a long multi-word passphrase beats a short scramble with symbols.
- Never reuse a password across sites; check your email against a breach service separately.
- For real security use a password manager to generate and store a unique long random password.
Frequently asked questions
Is this an entropy or crack-time calculation?
No, and you should be wary of tools that claim precise crack times. It is a structural checklist you can reason about, with its limits stated openly.
Is my password safe to type here?
The checks run in your browser and nothing is transmitted or stored. As a rule, do not type a live password into any site you do not control.
Why does a long passphrase score five without symbols?
Two of the five points are for length alone, and a long passphrase earns both — deliberately, because length has the biggest practical effect.
Can I check a password against known breaches?
Not here. Breach lookups need a service that holds the list; this tool is deliberately offline.
