Check a password without sending it to us
Use a password you can safely change. Do not enter a password that you are currently using on a critical account if this device or browser is shared.
Only a five-character SHA-1 hash prefix is sent directly to Have I Been Pwned. The password, full hash and result are not sent to our server, analytics, email or downloads. “Not found” does not prove safety.
How to read your result
Your browser computes a SHA-1 lookup hash and sends only its first five characters directly to the Have I Been Pwned range API. It compares the returned hash suffixes locally. Neither the password nor full hash is sent to Cloud Smart, reports or analytics. SHA-1 is used only to search this dataset, not as advice for storing passwords. Not found does not mean a password is strong, unique or safe.
Questions about this service
Do I need to give contact details?
No. The full result appears on this page. Any supported PDF or Word download is also free without contact details. The report email form is optional and appears after the result.
What happens to my entries?
Calculations and worksheets run in your browser without saving entries to our server. The domain checker sends your domain to our server and a public DNS resolver. The password checker sends only a five-character hash prefix directly to the range service. If you explicitly request an email, your full report is emailed to you; your contact details, tool name and result summary go to support@cloudss.co.uk.
Is the result a guarantee or a quote?
No. Use it as a starting point for a practical review. Recommendations depend on what you enter, and any service scope, licence or price is confirmed in writing.
Keep control of your information
Do not enter passwords, recovery codes or confidential customer records into a worksheet. The dedicated password check is the only tool designed to process a password, entirely in your browser. You can refresh the page to clear entries.
