Free Strong Password Generator
Generated locally in your browser using the Web Crypto API — never sent anywhere as plaintext.
Strength: very strong
Save this password (optional)
What is SaveIt's password generator?
It's a free, browser-based tool that creates a random, cryptographically secure password on demand — no app to install, no account, and no data sent to a server during generation. It works the same way for anyone, anywhere: open the page, adjust length and character types, and copy a password that's actually random rather than something a human (or a cracking dictionary) could predict.
How it works, technically
Your browser's built-in Web Crypto API (specifically crypto.getRandomValues) generates cryptographically random bytes — the same class of randomness operating systems use for encryption keys, not the weaker Math.random() that many "free password generator" sites still use under the hood. Those random bytes are mapped onto the character set you've selected (uppercase, numbers, symbols) to build a password of your chosen length — entirely inside your browser tab, before anything is copied or saved.
What makes a password strong?
A strong password is long, random, and unique to each account. Attackers don't guess passwords one by one — they run breached-password lists and brute-force tools that try billions of combinations per second. A truly random 16-character password with mixed case, numbers, and symbols is effectively impossible to crack with current technology, while a short or predictable password (birthdays, common words, keyboard patterns) can fall in seconds.
Truly random, not guessable
Built on the Web Crypto API's secure random generator — not a predictable pseudo-random algorithm.
Adjustable length & characters
Dial in length from 8 to 32 characters and toggle uppercase, numbers, and symbols to match any site's rules.
Zero-knowledge saving
Optionally save a password encrypted with your own PIN — we never see the plaintext, ever.

How to generate a secure password
- 1. Set your length — 16+ characters is recommended for important accounts.
- 2. Enable character types — keep uppercase, numbers, and symbols on unless a site restricts them.
- 3. Copy your password — click Copy and paste it straight into the account you're securing.
- 4. (Optional) Save it encrypted — log in, choose a PIN, and store it for later without ever exposing the plaintext to us.
Password security tips beyond generation
- Turn on two-factor authentication wherever it's offered. Even a perfectly random password can be phished — 2FA means a stolen password alone isn't enough to get in.
- Change a password immediately after a breach notice. If any service you use announces a breach, rotate that password (and anywhere else you reused it) right away.
- Never send a password over chat, email, or text. If you must share access, use a service built for it, or share the PIN and saved-password link separately.
- Longer beats "clever" every time. A 20-character random password is safer than a 10-character one with substituted symbols — length is the biggest lever you control.
- Don't forget non-login secrets. Wi-Fi passwords, API keys, and PINs benefit from the same random generation — this tool works for any of them, not just account logins.
Free forever — what an account adds
Password generation itself is never restricted — no daily limit, no watermark, no upsell mid-generation. Creating a free SaveIt account adds one thing: the option to save a generated password, encrypted with your own PIN, so you can find it again later without writing it down anywhere insecure. That's it — there's no separate paid tier for this tool today.
Frequently asked questions
Is this password generator actually secure?+
Yes. Passwords are generated locally in your browser using the Web Crypto API's cryptographically secure random number generator (crypto.getRandomValues) — the same standard used by password managers. Nothing is transmitted to a server during generation.
How long should my password be?+
For most accounts, use at least 12–16 characters with uppercase, numbers, and symbols enabled. Longer passwords are exponentially harder to brute-force; 16+ characters is a safe default for anything important like email or banking.
What happens if I save a password — do you see it?+
No. When you save a password, it's encrypted in your browser with AES-GCM using a key derived from your personal PIN (via PBKDF2) before it's sent. Your server only ever stores ciphertext, and your PIN itself is never transmitted — we cannot decrypt or recover your saved passwords.
What if I forget my PIN?+
Because the PIN never leaves your device and we don't store it, there's no way for us to recover a saved password if you forget the PIN used to encrypt it. Keep your PIN somewhere safe.
Should I use a different password for every account?+
Yes — reusing a password means one breached site can expose every other account using the same password. Generate a unique password for every account; a password manager (or SaveIt's encrypted saving) makes this practical.
Do I need an account to use the generator?+
No. Generating and copying a password works with zero signup. An account is only needed if you want to save a password for later.
Does this work on mobile?+
Yes — it runs in any modern mobile browser (iOS Safari, Chrome, etc.) exactly the same way as on desktop, since it's all standard browser JavaScript with no app install required.
