Are generated passwords truly random?

Yes — Formly uses the browser's cryptographically secure random number generator (window.crypto), the same standard used by security professionals and password managers.

What makes a password strong?

A strong password has: 12+ characters, a mix of uppercase and lowercase letters, numbers, and symbols, no dictionary words, and is unique to each account. Our generator creates passwords meeting all these criteria.

Password entropy measures how unpredictable a password is in bits. Higher entropy = harder to crack. A 128-bit entropy password would take longer than the age of the universe to brute-force.

Should I store generated passwords in a browser?

For maximum security, store passwords in a dedicated password manager (Bitwarden, 1Password, etc.) rather than your browser, which can be compromised by extensions.

Frequently Asked Questions

Is this password generator free?›

Yes, 100% free with no account or sign-up required. Generate as many passwords as you need.

How is the randomness generated?›

Passwords are built using the Web Crypto API (crypto.getRandomValues), the same cryptographically secure random source used by security software. It is far stronger than Math.random().

How strong should my password be?›

For most accounts, aim for at least 70 entropy bits (shown on screen). A 16-character password using uppercase, lowercase, numbers, and symbols typically exceeds 100 bits, which would take billions of years to crack with current hardware.

What are common use cases?›

Creating strong passwords for new accounts, generating random API keys or secret tokens, producing passphrases for password managers, and bulk-generating temporary credentials for testing environments.

Are generated passwords stored anywhere?›

No. Passwords are generated entirely in your browser and are never transmitted to any server. Close the tab and they are gone.

What Is Secure Password Generator?

A password generator creates cryptographically secure random passwords of customizable length and character composition. Formly's free password generator supports lengths from 8 to 128 characters, uppercase/lowercase letters, numbers, and symbols — with a live password strength meter. All generation happens in your browser using the Web Crypto API, meaning no password is ever transmitted anywhere. Also includes a passphrase generator using dictionary words for memorable but secure credentials.
