Free tool
Generate strong passwords instantly
Create random, secure passwords with customizable length and character sets — processed locally in your browser, inspired by enterprise-grade credential hygiene.
Generated locally in your browser. Nothing is sent to passwhy servers until you save a credential in the app or extension.
More than a password generator
Store, autofill and audit every credential
Random passwords are only the first step. passwhy helps teams vault credentials, enforce access controls and prove who revealed or copied a secret.
- Browser extension autofill on any site
- Encrypted vaults with role-based access
- Audit logs for reveal, copy and save actions
In the browser extension
Open the passwhy popup on any signup or password reset page — generate, copy or fill a strong password without leaving the tab.
Install from your build at browser-extension/dist/chrome for local testing.
Frequently asked questions
- How does the password generator work?
- Choose length and character types, then click Generate. passwhy builds a random password using your browser’s secure random number generator — nothing is uploaded.
- Is it safe to use online?
- Yes. Passwords are created entirely in your browser. We do not send generated passwords to our servers unless you explicitly save them in passwhy.
- How is this different from the extension?
- The web tool is great for one-off generation. The passwhy browser extension can also generate, copy and fill passwords directly into login forms.
Stop reusing passwords across sites
Save generated passwords in passwhy vaults, share them securely with your team and retire the spreadsheet.
