🔐 Password Generator
Create strong, random passwords with one click. 100% free, no signup — everything runs in your browser.
This free password generator creates strong, random passwords in one click, using your browser's built-in cryptographic random number generator. Choose a length, tick the character sets you want — uppercase, lowercase, numbers, symbols — and copy a password that is practically impossible to guess or brute-force. Unlike passwords invented by humans, which lean on names, birthdays and keyboard patterns, a randomly generated password has no structure for attackers to exploit. And unlike many online generators, this one never sends anything over the network: the password is generated on your device and exists nowhere else. With data breaches exposing billions of reused credentials every year, a unique random password for every account is the single most effective upgrade you can make to your personal security.
How to use
- Set the password length with the slider. Twelve characters is a sensible minimum; 16 or more is recommended for important accounts.
- Tick the character types to include — uppercase letters, lowercase letters, numbers and symbols. More variety means a stronger password.
- Click Generate password. A new random password appears instantly.
- Not happy with it? Click Generate again — you can create as many as you like, free.
- Click Copy to place the password on your clipboard, then paste it into the signup form or your password manager.
- Store it in a password manager rather than a text file or sticky note — the generated password appears nowhere else and cannot be recovered if lost.
Why use our password generator?
The biggest reason to use our generator is where the password is made: on your device, never on a server. Passwords are produced with the Web Crypto API — the same cryptographically secure randomness used by encryption software — and are never transmitted, logged or stored. A password only you have ever seen is fundamentally safer than one that passed through someone else's infrastructure.
It is also built for real-world use. Some websites reject symbols or cap length, so you can tune the character sets and length to fit any site's rules and regenerate instantly until one is accepted. Need a numeric PIN instead? The random number generator does that with the same secure randomness. Sharing your Wi-Fi with guests? Put the new password in the QR code generator so visitors scan instead of typing 20 characters. And remember that encoding is not encryption — if you are curious what Base64 actually does to text, see our Base64 encoder/decoder.
Who is this tool for?
Everyone with online accounts needs this tool, but some groups need it most. Remote workers and freelancers juggle dozens of client logins — CMS dashboards, hosting panels, invoicing apps — and reusing one password across them puts every client at risk. Generating a unique password per service, stored in a password manager, closes that hole in minutes.
Small business owners and IT admins use it when creating accounts for new employees, setting router and database credentials, or rotating passwords after staff changes. Developers reach for it to fill in API secrets, test-user credentials and one-off tokens during development. Students securing their first email, banking and university accounts can start with good habits instead of 'name123'. And families setting up a password manager together can generate a strong master-worthy password for each member in seconds. If a password protects money, work or identity, it deserves to be random.
Frequently asked questions
Yes. They are generated on your device with your browser's cryptographic random generator (Web Crypto API) and are never sent, logged or stored anywhere. Nobody — including us — ever sees them.
Length first, variety second. Every extra character multiplies the number of possible passwords, so a random 16-character password with mixed character sets would take modern hardware an astronomically long time to brute-force.
At least 12 characters for everyday accounts and 16+ for email, banking and anything holding payment details. Your email deserves the strongest password of all, since it can reset most other accounts.
It is astronomically unlikely. A 16-character mixed password has more possible combinations than there are grains of sand on Earth — by many orders of magnitude.
Yes. Password reuse is how one leaked database becomes ten hacked accounts, via 'credential stuffing' attacks. Generate a unique password per site and let a password manager remember them.
You don't — a password manager does. You only memorize one strong master password; the manager stores the rest and fills them in for you.
Some sites ban certain symbols or cap the length. Adjust the options — for example, turn off symbols or shorten the password — and generate again until it fits their rules.
