Generate a Strong Password
It is safe — everything happens in your browser. No data is sent to a server or stored anywhere.
Strong: it would take 20,506 billion years to brute-force this password
Runs locally only
The password is generated in your browser using the Web Crypto API and never leaves your device.
Cryptographic randomness
Uses crypto.getRandomValues — a cryptographically secure RNG, not Math.random.
Zero logging
We do not store, transmit, or log generated passwords. Complete privacy by design.
Frequently asked questions
What makes a password strong?
A strong password is at least 12-16 characters long and combines uppercase, lowercase, digits, and symbols. Entropy above 80 bits makes brute-force attacks practically impossible.
Is it safe to use an online generator?
Our generator runs entirely on your device. The password is created in the browser via the Web Crypto API and is never sent to a server. Nobody, including us, can access it.
Where should I store generated passwords?
Use a dedicated password manager: Bitwarden, 1Password, or KeePass. Avoid storing passwords in plain text files or your browser without a master password.
How often should I change passwords?
Change passwords when you suspect a breach or after a service is compromised. Modern best practice: don't rotate without reason — use a unique strong password per site plus two-factor authentication.
What is password entropy?
Entropy is a measure of randomness in bits. Higher means harder to guess. 60 bits is a minimum for important accounts, 80+ bits is bank-grade protection.
