🔐Strong Password Generator

Online strong password generator — cryptographically random

Our free password generator creates random passwords directly in your browser — without sending anything to a server. We use crypto.getRandomValues, the same mechanism used by cryptographic systems, so every password is truly unpredictable. You can set the length from 4 to 64 characters and choose which character classes to include: uppercase and lowercase letters, digits, and special characters. The strength indicator will tell you whether the chosen configuration is secure enough.

How to create and store secure passwords?

A strong password should be long (at least 12–16 characters), unique for each service, and contain no dictionary words or personal data. You don't need to memorize every password — use a password manager like Bitwarden (free and open source), 1Password, or KeePass. Generate a password here with one click, copy it, and store it securely in your manager. Never reuse the same password in more than one place — a data breach at one service won't then put your other accounts at risk.

Frequently asked questions

Is the password generator secure?

Yes. Passwords are generated exclusively in your browser using the cryptographic API (crypto.getRandomValues). The generated password never reaches any server — no one but you can see it.

How many characters should a strong password have?

We recommend at least 16 characters mixing uppercase, lowercase, digits, and special characters. The longer the password, the harder it is to crack by brute-force — even 12 characters can take millions of years to break.

What does the "no ambiguous characters" option mean?

This option excludes characters that look similar and can cause confusion when transcribing — such as O and 0 (letter O and digit zero) and I, l, and 1 (uppercase I, lowercase L, and one). Useful when you need to type the password manually.

Should I use a password manager?

Absolutely. A password manager (e.g. Bitwarden, 1Password, KeePass) lets you store unique, strong passwords for every service without having to memorize them. Our generator works great with managers — generate a password, copy, and paste it into your vault.
