Password Tools
Practical tools for the password-related work that isn't generating a single password: writing a policy, validating input, or working within a specific application like Excel.
Which Tool Do I Need?
These three tools solve problems that come up around password generation rather than during it — deciding what a password must look like, checking that a specific string matches those rules, and working inside software (like a spreadsheet) that has its own quirks. None of them replace the main Password Generator; they cover the surrounding work.
| If you need… | Use this tool |
|---|---|
| A written password policy to share with a team or client | Password Policy Generator |
| A regex to validate password format in a form or API | Password Regex Generator |
| A password generated inside a spreadsheet, without leaving Excel | Password Generator for Excel |
All Password Tools
Password Policy Generator
Build a clear, enforceable password policy for your organisation or application — minimum length, character requirements, expiry and history rules.
Build a policy →Password Regex Generator
Generate a validation regex from a set of requirements — length, character classes, and more. Works with JavaScript and most PCRE-compatible engines.
Build a regex →Password Generator for Excel
Generate passwords directly in Microsoft Excel with a built-in formula, or a VBA macro for cryptographically stronger output.
