Password Policy Tester

Define password rules (length and character requirements) and instantly see whether a password meets your policy.

Prototype your password rules safely

Use this tester to design and sanity-check a password policy before you implement it in your app. Adjust the sliders and toggles, then try a few real-world example passwords.

Reminder: even a strong policy does not replace secure server-side hashing and two-factor authentication.

Password policy

Configure the rules you want a password to satisfy.

Test a password

Type a sample password to see whether it passes the current policy and which rules fail.

Policy resultWaiting for input
  • Minimum length 12
  • Contains lowercase letter (a–z)
  • Contains uppercase letter (A–Z)
  • Contains number (0–9)
  • Contains symbol (!@#$…)

Why test your password policy?

A clear, well-balanced password policy helps users create strong credentials without making sign-up flows frustrating. This tool lets you experiment with different rules and instantly see how a sample password passes or fails.

Strong security usually comes from a combination of length and a mix of character types, plus account protections like rate limiting and two-factor authentication.

Important: MD5 and SHA-1 are not safe for storing passwords. Even with a strict policy you should always hash passwords on the server using a slow, salted algorithm (bcrypt, Argon2, PBKDF2, etc.).

How It Works

The Password Policy Tester runs entirely in your browser using JavaScript. Unlike other tools that send your data to a server, we process everything locally on your device. This guarantees 100% privacy and blazing fast speed.

  • No server interaction – data never leaves your device
  • Instant results since there is no network latency
  • Works offline once the page is loaded
  • Free to use with no usage limits

How to Use

1

Set your policy

Choose minimum length and which character types (upper, lower, numbers, symbols) you want to require.

2

Type a sample password

Enter any password to see which rules it passes or fails, in real time.

3

Tune the rules

Adjust the policy until it feels strong enough without being impossible for real users.

Example Usage

Use the tester to iterate on your password rules and check sample passwords before enforcing them in production.

Input
Policy: - Minimum length: 12 - Require: lowercase, uppercase, numbers, symbols Password: SecureP@ssw0rd!
Output
Result: PASS - Length ≥ 12 ✔ - Contains lowercase ✔ - Contains uppercase ✔ - Contains number ✔ - Contains symbol ✔

Frequently Asked Questions

Is a complex policy always better?
Not necessarily. Very strict rules can push users toward predictable patterns or reusing passwords. A long passphrase or 12–16 character password with mixed types is often better than forcing lots of arbitrary rules.
What else should I do besides a policy?
Always store passwords with a slow, salted hash (bcrypt, Argon2, PBKDF2), enforce rate limiting or lockouts on repeated failures, and enable two-factor authentication for important accounts.
Does any of my input leave the browser?
No. All checks happen locally in your browser. We do not send or store your password or policy settings.
