Free Password Generator
Create strong, random passwords with cryptographic security — generated on your device, never sent anywhere.
Strong passwords without the headache
Weak and reused passwords remain the number one way accounts get hijacked. The fix is simple: long, random, unique passwords for every site — and a generator to make them painless. Utilo's free password generator uses your browser's built-in cryptographic randomness (the same grade of randomness behind TLS encryption), so every password is genuinely unpredictable. Customize the length from 8 to 64 characters, pick exactly which character sets to include, and watch the live entropy meter tell you how strong the result is.
Because generation happens entirely on your device, there is no server that could log, leak, or sell your passwords. There is nothing to sign up for and nothing to install. Generate one, copy it into your password manager, and move on — that is the entire workflow, and it takes about five seconds.
For the full system — memorable passphrases, password managers, two-factor authentication, and the habits that actually prevent account takeovers — read how to create a strong password you can remember.
How to use the password generator
- Set the length: 16+ characters is recommended for important accounts; 20–32 is ideal.
- Choose character types: keep all four enabled for maximum strength, or narrow them to fit a site's rules.
- Generate and copy: hit Generate, check the strength meter, then copy the password into your password manager.
Frequently asked questions
Is it safe to generate passwords online?
With this tool, yes. Passwords are created using crypto.getRandomValues inside your own browser and never leave your device. There is no server involved at any step.
How long should my password be?
Use at least 16 characters for important accounts like email and banking. Longer is always better — each additional character multiplies an attacker's work enormously.
What is password entropy?
Entropy, measured in bits, describes unpredictability. A 20-character password drawn from upper, lower, digits, and symbols carries about 131 bits of entropy — far beyond any brute-force attack.
Should I reuse passwords across sites?
No. Reusing passwords means a single breach exposes every account that shares it. Generate a unique password per site and store them in a password manager.
What does "exclude ambiguous characters" do?
It removes easily confused characters — lowercase L, uppercase i, digit 1, uppercase O, digit 0 — which helps when you must read a password aloud or type it from print.
