Password Generator
Generate strong, secure random passwords instantly. Customize length, characters, and create bulk passwords online — 100% browser-based, no data leaves your device.
What is a password generator?
A password generator is a tool that creates random, strong passwords automatically. It uses cryptographic randomness to produce passwords that are difficult to guess or crack, helping protect your online accounts.
How does the password generator work?
The generator uses the Web Crypto API — a cryptographically secure random number generator built into your browser. Characters are randomly selected from your chosen character set to form each password.
Are the generated passwords stored anywhere?
No. All password generation happens entirely in your browser. No data is sent to any server, and nothing is stored or logged anywhere. Your passwords remain completely private.
What makes a password strong?
A strong password combines uppercase and lowercase letters, numbers, and special characters. It should be at least 12 characters long, avoid common words or patterns, and be completely random.
How long should my password be?
We recommend at least 12 characters for most accounts. For important accounts like email or banking, use 16 or more characters. Longer passwords are exponentially harder to crack.
Can I generate multiple passwords at once?
Yes. You can specify a bulk count to generate multiple passwords simultaneously. This is useful when you need passwords for multiple accounts or want to choose from several options.
What does "avoid ambiguous characters" mean?
This option removes characters that are easily confused with each other, such as lowercase L (l), uppercase I (i), and zero (0). This is helpful when passwords need to be read aloud or typed manually.
Should I use special characters in my password?
Yes, including special characters like !@#$%^&* significantly increases password strength by expanding the pool of possible characters, making brute-force attacks much more difficult.
Can I customize which characters are included?
Yes. You can toggle uppercase letters, lowercase letters, numbers, and special characters independently. You can also exclude ambiguous characters for easier readability.
Is it safe to use an online password generator?
Yes, when the generator runs entirely in the browser like this one. Since no data is transmitted to any server and everything is processed locally, the generated passwords are as secure as local generation.
How often should I change my passwords?
Current security guidelines recommend changing passwords only when there is a reason to believe they may be compromised, rather than on a fixed schedule. Use unique passwords for every account.
What is the difference between a password generator and a password manager?
A password generator creates random passwords, while a password manager stores and organizes them. They work best together — use a generator to create strong passwords and a manager to remember them.
How to Use Password Generator
Password Generator creates strong random passwords and can produce them in bulk, entirely inside your browser. Nothing is sent anywhere, so your new passwords never leave your device.
- Set 'Length:' to choose how many characters each password should contain.
- Set 'Count:' to the number of passwords you want to generate in one batch.
- Select the character sets to include — 'a-z' for lowercase, 'A-Z' for uppercase, '0-9' for digits, and '!@#$' for symbols.
- Enable 'Avoid ambiguous' to skip look-alike characters such as l, 1, I, O, and 0.
- Copy the generated passwords from the results and store them in your password manager.
Enable 'Avoid ambiguous' whenever a password will be read aloud or typed by hand — characters like l, 1, I, O and 0 are easy to confuse.
