Password Generator
Create strong, secure passwords instantly with our free online Password Generator. Everything runs in your browser, so your generated password is not sent to a server.
What is a Password Generator?
A Password Generator creates random passwords based on the options you choose. You can control the password length and select uppercase letters, lowercase letters, numbers, and symbols to create a password that fits the requirements of your account or service.
This Password Generator runs directly in your browser. The generated password is created locally rather than being sent to a server as part of the generation process.
How to use the Password Generator
- Choose the password length: Use the slider to select a length between 6 and 64 characters.
- Select character types: Choose uppercase letters, lowercase letters, numbers, symbols, or any combination of these options.
- Generate the password: Click Generate Password to create a new random password.
- Check the strength indicator: The tool provides an estimated strength level based on password length and the size of the selected character set.
- Copy the password: Click the copy icon next to the generated password to copy it to your clipboard.
Why use a strong password?
Strong, unique passwords make it harder for unauthorized users to guess or compromise your accounts. Using a different password for each important account also limits the damage if one password is exposed.
Longer passwords generally provide more possible combinations. A randomly generated password can also help you avoid predictable choices such as names, birthdays, common words, or repeated patterns.
Password security best practices
- Use sufficient length: Longer passwords generally provide more resistance to guessing attacks.
- Use unique passwords: Avoid reusing the same password across multiple accounts.
- Avoid personal information: Do not use easily associated information such as names, birthdays, or addresses.
- Consider a password manager: A reputable password manager can help you create and store unique passwords securely.
- Enable multi-factor authentication: When available, use an additional authentication factor to provide another layer of account protection.
Understanding the password strength indicator
The strength indicator provides an estimate based on the password length and the number of possible characters selected. It uses a simplified entropy calculation to classify the result as Very Weak, Weak, Fair, Strong, or Very Strong.
This indicator is a useful comparison between different settings, but it should not be treated as a guarantee that a particular password is safe against every type of attack.
