Password Strength Analyser
Check the practical strength of a password without sending it to a server. The analyser highlights length, character variety, and common patterns so you can make a safer choice.
A QUICK WALKTHROUGH
How to use this tool
- Enter a password in the private analyser.
- Review the score, estimated entropy, and suggestions.
- Improve weak patterns and use a unique password for every account.
Designed for local analysis
The password is inspected in your browser and is not uploaded, saved, or logged by this page. Clear the field when you are finished, especially on a shared device.
Length matters most
The score considers length, character groups, repeated characters, sequential patterns, and common words. A longer unique passphrase is usually easier to remember and stronger than a short complex-looking password.
A practical estimate, not a breach check
This analyser does not compare your password with a remote breach database and cannot guarantee that a password is unused. Use a password manager and turn on multi-factor authentication where available.
GOOD TO KNOW
Common questions
Is my password sent anywhere?
No. Analysis runs locally in your browser. Do not enter a password on a device or page you do not trust.
What makes a password strong?
Length, uniqueness, and unpredictability matter most. Avoid names, dates, keyboard patterns, repeated text, and passwords reused on another service.
Does this check leaked passwords?
No. It does not query a breach database. Treat any password that has been reused or exposed as unsafe and replace it.
Should I use a password manager?
Yes. A reputable password manager can create and store a different long password for each account.
