About the tool
A free, secure password generator that works entirely in your browser
This password generator creates strong, random passwords in one click — with no sign-up and no limits. Unlike a simple random picker, it uses the browser's Web Crypto API(crypto.getRandomValues), the same cryptographically secure source trusted for real security work. That means the passwords it produces are genuinely unpredictable and safe to use on your accounts.
Build a strong password your way
Set the length anywhere from 4 to 64 characters with the slider, then choose which character types to include: lowercase, uppercase, numbers, and symbols. The generator guarantees at least one character from every type you select, so your password always meets common complexity rules. Turn on exclude look-alike characters to drop easily-confused characters like l, I, 1, O, and 0 when you need to type or read the password by hand.
See how strong it is
Every password comes with a live strength meter that estimates entropy in bits — a measure of how many guesses an attacker would need. As a rule of thumb, longer passwords with more character types score higher. Aim for at least 12–16 characters for everyday accounts, and 20 or more for high-value logins like email, banking, or your password manager's master password.
Private by design
Security tools should not phone home, and this one doesn't. Your password is generated locally and never leaves your device — nothing is sent over the network, logged, or stored on our servers. The recent-passwords list you see is kept only in memory for the current session and is discarded the instant you reload or close the tab. Copy the one you want, paste it where you need it, and move on.
Good password habits
Use a unique password for every account so a single breach can't cascade, and store them in a reputable password manager rather than trying to memorise them. Enable two-factor authentication wherever it's offered for an extra layer of protection. When you need randomness for something other than passwords, the rest of the toolkit is a click away — random numbers, a coin flip, or a random name for a new project or username.
However you use it, this free password generator is built to be fast, secure, and genuinely random. Set your length, pick your character types, and generate a strong password — as many as you like, completely free, with nothing sent anywhere or stored on our servers.
FAQ
Password generator FAQ
Is this password generator safe to use?
Yes. Passwords are created entirely in your browser using the Web Crypto API (crypto.getRandomValues), which is cryptographically secure. Nothing is sent over the network, logged, or stored on our servers, and the on-page list is kept only in memory for your current session — it's cleared the moment you reload or close the page.
What makes a strong password?
Length matters most: aim for at least 12–16 characters. Mixing lowercase, uppercase, numbers, and symbols increases the number of possible combinations, which makes a password much harder to guess or brute-force. The strength meter estimates entropy in bits — higher is better, and anything over 60 bits is strong for most accounts.
How long should my password be?
For everyday accounts, 16 characters with mixed character types is a solid default. For high-value accounts like email, banking, or a password manager's master password, consider 20 or more. You can set any length from 4 to 64 with the slider.
What does “exclude look-alike characters” do?
It removes characters that are easy to confuse when reading or typing — like the lowercase L, capital I, the number 1, the letter O, and zero. Turn it on when you'll need to type the password by hand or read it aloud; leave it off for maximum randomness when a password manager will store it for you.
Should I use a different password for every account?
Yes. Reusing a password means that if one site is breached, every account sharing that password is at risk. Generate a unique password for each account and store them in a reputable password manager so you don't have to remember them all.
Do you store the passwords I generate?
No. There is no server involved in generating your password — it all happens locally in your browser. We never see, transmit, or save your passwords, and the recent list is in-memory only and discarded when you leave the page.
