What Is a Password Generator?
A Password Generator creates passwords that are hard to guess because they come from a random process instead of a human mind. People tend to pick predictable words, names and dates, and attackers know it. A random mix of letters, numbers and symbols takes far longer to crack, even for software that tries billions of guesses per second.
This Password Generator uses the Web Crypto API built into your browser, the same kind of cryptographically secure randomness used for encryption keys. It avoids the bias that plain random functions can introduce. You control the length from 6 to 64 characters, choose which character types to include, and can drop look-alike characters such as 0, O, 1, l and I when you might need to read the password aloud or type it from paper.
The strength meter estimates entropy, which is the length multiplied by the number of bits in each character choice. More entropy means more guesses are required. As a rule of thumb, 60 bits is respectable and 80 bits or more is very strong for online accounts.
How to Use the Password Generator
- Drag the length slider. Sixteen characters is a sound default, and longer is better for important accounts.
- Tick the character types you want: uppercase, lowercase, numbers and symbols. Some websites reject certain symbols, so untick symbols if a site complains.
- Turn on the look-alike option if you will need to type the password by hand.
- Pick how many passwords to create. Generating five or ten lets you choose one you like.
- Watch the strength meter. Aim for Strong or Very strong.
- Press Copy next to a password and paste it straight into your password manager or the sign-up form.

Benefits of Using an Online Password Generator
Reusing passwords is the most common reason accounts get taken over. When one site leaks its database, attackers try the same email and password on banks, shops and social networks. A Password Generator makes it painless to give every account its own unique password.
Because the passwords are produced right in your browser, there is no server that could log or leak them. Pair the tool with a password manager so you do not need to memorize the results.
Your privacy comes first. The Password Generator runs entirely in your web browser. Nothing you enter is sent to our servers, which keeps your data private and makes results appear instantly. See our Privacy Policy for details.
Common Use Cases for the Password Generator
- Creating a unique password for each new account you sign up for
- Replacing weak or reused passwords after a data breach notice
- Generating Wi-Fi network passwords for home, office or guests
- Making temporary passwords for new team members or clients
- Producing strong passwords for databases, servers and admin panels
- Creating secret keys and tokens for development and testing
- Setting up passwords on shared devices, smart TVs and game consoles
- Teaching family or students what a good password looks like
Tips for Getting the Best Results
- Use a reputable password manager so every password can be long and random without you memorizing it.
- Turn on two-factor authentication wherever it is offered. A strong password plus a second factor is far safer than either alone.
- Length beats complexity. A 20-character password with only letters and numbers can be stronger than an 8-character one full of symbols.
- Never share passwords in chat messages or email. If you must share access, use your password manager's sharing feature.
- Change a password right away if you suspect a service was breached or you typed it on an unfamiliar device.
- For passwords you must type often, such as a laptop login, consider a long passphrase of several random words instead.
Password Generator FAQ
Is this Password Generator safe to use?
Yes. The passwords are created locally in your browser with secure random numbers. They are never sent to a server or saved, and closing the page erases them.
How long should my password be?
At least 12 characters for ordinary accounts and 16 or more for email, banking and anything that can reset other accounts. Longer passwords are harder to crack.
Why exclude look-alike characters?
Characters such as 0 and O or 1, l and I look nearly identical in many fonts. Excluding them reduces typing mistakes when you read a password from paper or a screen.
What does entropy mean in the strength meter?
Entropy measures unpredictability in bits. Each extra bit doubles the number of guesses an attacker needs on average. The meter turns that number into labels from Weak to Very strong.
Why does a website reject my generated password?
Some sites limit length or ban certain symbols. Untick Symbols or shorten the length, then generate again. Numbers and mixed-case letters are accepted almost everywhere.
Can you see or recover my passwords?
No. We never receive them, so there is nothing to recover. Copy a password to your manager before leaving the page.
