Is this password generator really free?

Yes. There is no account, no sign-up, no paid tier and no limit on how many passwords you generate.

Are the passwords stored anywhere?

No. Passwords are created by your browser using the built-in Web Crypto API and are never sent to our servers, logged or saved by this page. If you copy one, it may remain in your device's clipboard or clipboard history.

How long should my password be?

For randomly generated passwords, 16 characters is a strong baseline and 20 is the recommended default here. For a password manager's master credential, a long memorable passphrase can be more practical than memorizing a random character string.

Are randomly generated passwords safer than ones I invent?

Yes. Human-chosen passwords follow predictable patterns, such as words with a capital first letter and a number at the end. Random generation removes those patterns, so attackers cannot narrow the search.

What does 'avoid ambiguous characters' do?

It removes characters that are easy to confuse when reading or typing a password: I, l, 1, O, 0 and similar. It slightly reduces entropy, so increase the length a little if you enable it.

Should I use a different password for every account?

Yes. If one site is breached, reused credentials let attackers into your other accounts automatically. A password manager makes unique passwords practical.

How this password generator works

Every password is built in your browser with crypto.getRandomValues(), the operating system's cryptographically secure random number source. Each character is picked independently from the character set you choose, using rejection sampling so no character is more likely than another. There is no server call, request log or page storage. The generated password exists only in this page's memory until you leave or close it. If copied, it may remain in your device's clipboard or clipboard history.

What actually makes a password strong

Strength is measured in entropy: the number of guesses an attacker would need on average. Entropy grows with both the size of the character set and, more importantly in practice, the length. A 20-character password drawn from this generator's full 86-character pool carries roughly 129 bits of estimated entropy. That is a strong foundation, but no length makes an account invulnerable: unique credentials, a trusted password manager, MFA, and protection against phishing all matter too.

Recommended password lengths

16 characters — a strong baseline for randomly generated passwords, not an absolute security guarantee.
20 characters — the recommended default. This is the generator's default.
24+ characters — additional security when the service supports longer passwords. For a master credential, a long memorable passphrase can be more practical than memorizing a long random string.
Service limits — use a long unique password within the service's supported limits. Some poorly designed systems may impose compatibility restrictions.

Why a unique password per account matters

Credential stuffing is a common cause of account takeover. Attackers take email and password pairs exposed in one breach and replay them across many other services. Reuse turns a single unrelated breach into a compromise of your email, payments and recovery options. Generate a separate password for every account and store them in a password manager, so you only have to remember one strong master password.

Why browser-side generation is more private

A generator that builds passwords on a server has to transmit them back to you, which means they can appear in server logs, proxy caches, error reports or analytics payloads. Generating in the browser removes that entire class of exposure: the password exists only in the memory of your own tab until you copy it. You can verify this yourself — open your browser's network tab and generate a password; no request is made.
