What this tool helps with
Reusing or guessing passwords makes accounts easier to compromise. A unique random password is easier to generate than to invent by hand.
How to use it
- Choose a length between 8 and 128 characters.
- Select the character groups you want to include.
- Generate the password, then copy it into a trusted password manager.
Requirements
A modern browser with the Web Crypto API, normally available on HTTPS sites and localhost.
Limits and privacy
This tool does not store, sync, or manage credentials. Use a unique password for each service and store it in a reputable password manager. The generator cannot protect a password after you copy or share it. Inputs are processed locally in this browser. The site does not provide an upload endpoint for this tool.
Frequently asked questions
Is the password uploaded or saved?
No. It is generated in this browser tab and is not uploaded or saved by this site.
Why do I need HTTPS?
Browsers restrict cryptographic features on insecure origins. Use this tool on HTTPS or localhost.
Does a longer password guarantee account security?
No. Account security also depends on unique passwords, multifactor authentication, and the security of the service and your device.
