About breaches
A data breach happens when credentials are leaked from a service you use. Even one leaked password can compromise every account where you reused it.
This checker uses a privacy-preserving range query model — your full email is never sent to a server.

How often should I rotate passwords?
Change any password immediately after a breach. Otherwise, rotate high-value accounts every 6–12 months.
Do I need to create an account?
No. The generators are completely free and require no account. Register only if you want to save credentials in a vault.
Is PassGuru open source?
Our client-side tools are transparent — everything runs in your browser so you can verify nothing is uploaded.
Can I generate a passphrase instead of a password?
Yes. Use the Passphrase tool to build memorable multi-word credentials with custom separators and casing.
What is entropy?
Entropy measures how unpredictable a password is, in bits. Each additional bit doubles the effort required to crack it.
About PassGuru
PassGuru is a fast, private, browser-based password security suite built for individuals, developers and teams.
Privacy first
Everything runs client-side. Your credentials are never uploaded, stored or shared.
Fast & free
No account, no queue, no watermark. Generate a strong password in one click.
Bilingual
Full English and Chinese interfaces, switchable with one click.
Our story
Weak and reused passwords remain the number one cause of account compromise. Yet most password tools are either paid, opaque about privacy, or require an account just to copy a string.
PassGuru was built to remove that friction. One page, every generator, every check, all running locally in your browser — free forever.
Technology
Web Crypto API
Passwords are generated with a cryptographically secure random source — never Math.random.
Client-side analytics
Strength, entropy and crack-time estimates are computed entirely in your browser.
