A worked example
- Input
- A 16-character generated password with mixed case, digits and symbols.
- What comes back
- A high strength rating, with the password ready to copy.
- Worth knowing
- The score is a rule-of-thumb based on length and character variety. It does not check whether the password has appeared in a breach, and it has no idea whether you have used it elsewhere - which matters more than the score.
If it does not work
A password you consider strong scores low
The scoring rewards length and character variety. Length is the single biggest factor - add characters.
The copy button did nothing
Clipboard access can be blocked in private browsing. Select the text and copy manually.
Nothing happens when you run it

When to use Password Checker
Generating a strong new password
Create a long random password with the character types you choose, ready to save in a password manager.
Checking how a password is built
See whether a password has enough length and variety by common rules of thumb.
Teaching good password habits
Show someone how length changes the strength estimate.
Replacing a weak or reused password
Generate a new random password for an account whose password you have used elsewhere.
The two parts, explained
Everything happens in your browser. Nothing you type is sent anywhere:
- Check
- Type a password to see a strength estimate based on its length and variety of characters. Checking is not metered.
- Generate
- Set the options and press Generate for a random password. Generating counts against the daily allowance.
- Copy
- Copy the generated password straight into your password manager.
What it cannot do
- The score is a rule of thumb based on length and character variety. It does not check whether the password has appeared in a data breach.
- It cannot know whether you have reused the password elsewhere, which matters more than the score.
- It does not store or manage passwords.
- The free allowance is 5 generated passwords per day, counted in your browser and reset at midnight UTC.
How it compares with the alternatives
Password managers generate and store strong, unique passwords for every account, and many warn you when a saved password appears in a known breach. Using one is the single most effective step for most people.
This tool is a quick generator and a rough strength check that runs entirely in your browser.
How in-browser processing works, and exactly which tools are the exception, is explained on the why client-side page.
Getting a better result
Length beats complexity
A long passphrase is stronger and easier to remember than a short, complex password.
Never reuse passwords
A unique password per site limits the damage of any breach.
Use a password manager
Let it store the generated passwords for you.
Turn on two-factor authentication
It protects you even if a password leaks.
Generate a different password for every account
Store them in a password manager rather than trying to remember them.
More questions about Password Checker
Is my password sent anywhere?
No. Checking and generating happen in your browser.
Does it check for breached passwords?
No. Use a breach-checking service or your password manager's alerts.
What counts against the daily limit?
Generating a password. Checking one you type is not metered.
How long should a password be?
Longer is better; many guides recommend at least 12 to 16 characters, or a passphrase of several random words.
Is a high score a guarantee?
No. A password can score well and still be in a breach list or reused. Uniqueness matters most.

Is my password sent anywhere?
No. Scoring and generation both run in this page. Nothing is transmitted, logged or stored - there is no network call in this tool at all.
Does it check breach databases?
No. Checking against a breach list would require sending data off the device, which this tool deliberately does not do.
Are the generated passwords random?
They are generated by your browser's random number generator in the page.
Is there a limit?
Generating a password is capped at 5 per day, counted in your browser and reset at midnight UTC. Checking the strength of a password you type is not metered.
