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.
- 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.).
Design Secure Rules
Stop guessing what makes a "good" password policy. Test your requirements against real-world inputs in real-time.
Real-time Checks
See exactly which rules pass or fail as you type. No page reloads needed.
Custom Logic
Toggle requirements for length, digits, symbols, and casing to find the perfect balance.
UX Testing
Ensure your policy is strict enough for security but not too annoying for actual users.
Visual Feedback
Clear Green/Red indicators help you verify that your validation logic works as expected.
How this Password Policy Tester works
This security compliance tool evaluates passwords against specific complexity rules to verify if they meet defined security policies. Users can define custom policies such as minimum length, required uppercase letters, digits, or symbols, and disallowed character patterns. The tool provides instant feedback on whether specific password inputs pass or fail the configured rules. It acts as a validator playground for developers and admins to test regex patterns before implementing them in authentication systems. Applications include configuring Active Directory password filters, designing validation logic for user registration forms, and auditing existing passwords against new, stricter standards to identify weak credentials.
How to Use
Set your policy
Choose minimum length and which character types (upper, lower, numbers, symbols) you want to require.
Type a sample password
Enter any password to see which rules it passes or fails, in real time.
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.
