Strong random passwords built from the browser crypto API. Free, runs entirely in your browser — your files are never uploaded.
How to use Password Generator
Set the length and which character types to include.
Check the entropy figure to see how strong the result actually is.
Copy the password straight into your password manager.
Frequently asked questions
Is it safe to generate a password on a website?
Here, yes, and you can verify why. Passwords are generated in your browser and never transmitted — the Content Security Policy blocks outbound connections from this page entirely, so there is no channel to send them over.
What does the entropy number mean?
It is the real strength in bits, calculated from the length and the character set, rather than a vague weak-to-strong badge. Each extra bit doubles the guessing effort; anything at or above 80 bits is comfortably beyond brute force.
Are the passwords truly random?
They use rejection sampling over the browser’s cryptographic random source, which avoids the modulo bias that skews naive implementations toward some characters.
How long should a password be?
Length beats complexity. Sixteen characters with mixed types is a sensible floor, and longer is better for anything protecting other credentials.
