Generated using the Web Crypto API in your browser. Nothing is ever sent across the network.
How it works
The generator draws bytes from window.crypto.getRandomValues, then maps each byte to your chosen alphabet. No network request is made, and no password is ever logged or saved.
Common ways people use it
- —Creating a unique password for a new account
- —Rotating an old password that may have been reused
- —Generating a temporary password to share with a colleague
- —Seeding a password manager with high-entropy values
Frequently asked questions
How long should a password be?+
For most accounts, 16 characters with mixed types is comfortably strong. For high-value accounts (email, banking, password manager master), use 20 or more.
Are generated passwords truly random?+
They come from the Web Crypto API, which uses a cryptographically secure random number generator provided by the operating system. That is the same source security libraries use.
Why does the tool warn against short passwords?+
Shorter passwords have fewer possible combinations, so a brute-force attack finishes faster. Length adds more strength than any single character-set tweak.
Should I save passwords in my browser?+
A dedicated password manager is safer than browser-stored passwords. Generate here, then paste into the manager.
