Free and secure password generator
Create a strong, unique, random password in one click. Everything happens in your browser: we never see your password, we never store it, it stays on your device.
How to generate a secure password?
Three steps to a strong password. No account.
1. Choose your options
Password length, numbers, uppercase, special characters: set it up, and you're done.
2. Generate in one click
The random password is created on your device, using your browser's secure cryptographic generator.
3. Copy and use
One click to copy your new password, and you're off. Nothing is saved, nothing is sent.
What makes a password strong?
A strong password is long, random, and used in exactly one place. Length matters far more than clever substitutions: swapping an "a" for an "@" fools no cracking tool anymore, while every extra character multiplies the number of combinations an attacker has to try.
That is what entropy means. An 8-character password picked by a human falls in minutes on consumer hardware. A 16-character password drawn at random from lowercase, uppercase, digits and symbols represents billions of billions of combinations: out of reach for a brute-force attack.
A randomly generated password has another advantage: it contains no birthday, no pet name, no site name. All things an attacker can guess, or simply read off your social media.
How long should a password be?
Here is what we recommend, per use case. When in doubt, go longer: a password manager will remember it for you.
Email account: 20 characters or more
Your email address resets every other account you own. It is the master key of the set, so it deserves the longest password, with two-factor authentication switched on.
Banking and government: 16 to 20 characters
Bank accounts, taxes, health, insurance. A long password, unique, never reused anywhere else, and rotated whenever the service reports a data breach.
Wi-Fi: 20 characters or more
You rarely type it and it protects your whole home network. Generate it long, keep it in your manager, and share it with a QR code rather than out loud.
Server, database, admin: 24 characters or more
Technical accounts are scanned around the clock by bots. There is no point trying to memorise these: generate long, store in a vault, and prefer an SSH key when you can.
Throwaway account: 12 to 16 characters
Forum, newsletter, free trial. Even with nothing at stake, keep the password unique: these sites are the first to have their database leaked.
Password mistakes to avoid
- Reusing the same password. This is mistake number one. A single leak on a small site makes your important accounts reachable with the very same email and password pair.
- Using personal information. First names, dates, favourite team, licence plate: all of it can be guessed, found online, or already sits in an attacker's dictionary.
- Trusting clever patterns. "Password2026!", "Qwerty123" or the site name followed by a digit are among the first combinations tested.
- Sending a password by email or text message. Those messages sit in plain text for years. Use your password manager's secure sharing instead.
- Skipping two-factor authentication. Even a perfect password cannot protect you from a breached website, but a second factor still blocks the login.
Frequently asked questions about password generation
Is this password generator actually safe?
Yes, for one simple reason: we never see your passwords. Every password is created locally, on your device, by your browser.
Our servers only serve the page, they never see what you generate.
Once the page is loaded, everything stays with you. We don't collect anything, we don't store anything. You can even cut your internet connection before generating: the generator keeps working.
Curious? The open-source password library is public.
Why use a different password for every site?
Picture this: a site you signed up for gets breached. Your password ends up online, in the wrong hands.
If you reused it elsewhere, those people now have the email and password combo to try your other accounts. It is an automated attack, replayed across thousands of sites in minutes. A unique password per service is the simplest protection.

How do you remember random passwords?
Use a password manager: it keeps everything encrypted in one place and fills your forms for you.
You only need to remember one secret, the one that unlocks the vault.
On the free and open-source side (anyone can audit the code), there's KeePass.
There are also great free options like Bitwarden.
Is this password generator really free?
Yes, entirely, with no usage limit. LFMDP runs on the shared infrastructure of
the Ludovic Frank group.
And because almost all the work happens in your browser, our servers barely lift a finger. Result: no ads, no sign-up, no limits.
If it's free, how do you make money?
We don't monetize LFMDP. By using it, you simply meet the Ludovic Frank brand, and if your company ever needs custom web work or consulting, you'll know where to find us.
We also ship focused paid software, like a restaurant booking tool that helps reduce no-shows.
LFMDP is also a simple way to discover our other services.
