Password Generator
Create strong, random passwords with cryptographic-grade randomness — entirely in your browser.
What is it?
A password generator is a small tool that creates a random sequence of characters strong enough to resist brute-force and dictionary attacks. Our online password generator uses the browser’s built-in cryptographic randomness (Web Crypto API), so the output is truly unpredictable — not a pseudo-random string. You decide the length and which character classes to include: lowercase letters, uppercase letters, digits, symbols, similar characters or ambiguous characters. The generated password never leaves your device, so you can copy it straight into your password manager without worry.
How to use it
- Choose the length you want — 16 characters or more is recommended for online accounts.
- Pick the character types: lowercase, uppercase, digits and symbols.
- Toggle “avoid similar characters” to skip easily-confused glyphs like O/0 or l/1.
- A password is generated automatically — click “Regenerate” to get a new one.
- Click “Copy” and paste it directly into your account or password manager.
Why use this tool
Reusing the same password across services is the leading cause of account takeovers. A strong, unique password for every account, stored in a password manager, is the single most effective security habit you can adopt. Our generator makes that habit painless: it produces high-entropy passwords on demand, with sensible defaults that pass modern best practices (16 characters, all four character classes). The randomness comes from the Web Crypto API, the same primitive used by browsers for TLS, so you do not have to trust JavaScript-level math libraries. Because the password is created entirely in your browser, no analytics or third-party request ever sees it. You can use the tool with confidence on a public network, on a borrowed laptop or even in incognito mode.
Frequently asked questions
How long should my password be?
For most online accounts, aim for at least 16 characters. For sensitive accounts (email, banking), 20 or more is even safer.
Are these passwords really random?
Yes. The tool uses the Web Crypto API, which delivers cryptographically secure random values produced by your operating system.
Should I include symbols?
Yes when the site allows it. Symbols add entropy and slow down brute-force attacks. Some legacy systems block them — in that case, just increase the length.
Is the password sent anywhere?
No. Generation is done entirely on your device. Nothing is sent, logged or saved on a server.
Can I use the tool offline?
Yes. After the page is loaded once, the generator continues to work even without internet, since the logic is shipped as plain JavaScript.
