7 tips for creating a secure password with this password generator
- Use a combination of upper and lower case letters, numbers, and special characters.
- Make the password at least 12 characters long.
- Avoid using common words or phrases that can be easily guessed.
- Use a passphrase instead of a single word, and use the first letter of each word in the phrase as your password.
- Avoid using the same password for multiple accounts.
- Change your password regularly to keep it secure.
- Never share your password with anyone.
It is also a good idea to use a password manager to help you generate and store strong, unique passwords for all of your accounts. A password manager can also help you keep track of your different passwords and ensure that you are using strong, unique passwords for each account.
What is a Password Generator?
A password generator is a tool that creates random, secure passwords based on customizable criteria such as length, character types, and complexity. Instead of relying on memorable words or patterns that attackers can guess, a good password generator uses cryptographically secure randomness to produce passwords that are resistant to brute-force, dictionary, and social engineering attacks.
This password generator runs entirely in your browser using the Web Crypto API (crypto.getRandomValues). Your password never leaves your device — it is not sent over the internet, stored on a server, or logged in any way. The built-in password meter evaluates strength in real time based on entropy, length, character diversity, and uniqueness.
How to Use This Password Generator
Follow these steps to generate a strong, secure password:
- Set password length — Use the number input or slider to set the desired length (8–128 characters). A minimum of 12–16 characters is recommended for strong security.
- Choose character types — Select which character sets to include: lowercase letters, uppercase letters, numbers, and symbols. At minimum, enable lowercase, uppercase, and numbers.
- Toggle additional options — Enable Avoid Similar Looking Characters to exclude easily confused characters like
0O1lI. Enable Insert Semicolon (;) and Comma (,) to add separators for readability. - Click Generate — Press the Generate button or press Enter to create a new random password.
- Check the password meter — Review the strength indicator. Aim for at least Good (yellow) or Strong (green) for sensitive accounts.
- Copy your password — Click Copy Password or the copy icon to copy the password to your clipboard.
Frequently Asked Questions
Is this password generator safe to use?
Yes. The password is generated locally in your browser using crypto.getRandomValues(), a cryptographically secure random number generator. No data is sent to any server, stored in any database, or logged. Once you close or refresh the page, the generated password is gone.
What password length should I use?
For most purposes, a password of at least 12 characters is recommended. For sensitive accounts like email, banking, or admin panels, use 16–24 characters. This tool supports up to 128 characters. Longer passwords with mixed character types provide exponentially more combinations and are far more resistant to brute-force attacks.
What do the password meter levels mean?
Weak (red, 0–25%) — Easily guessable; avoid using.
Fair (orange, 26–50%) — Moderate security; suitable for low-risk accounts.
Good (yellow, 51–75%) — Strong security; acceptable for most accounts.
Strong (green, 76–100%) — Maximum security; recommended for sensitive accounts.
Should I enable "Avoid Similar Looking Characters"?
Yes, especially if you need to read or type the password manually. This option removes characters like 0 (zero) and O (uppercase o), 1 (one) and l (lowercase L), and I (uppercase i) that are easy to confuse. The trade-off is a slight reduction in the total character pool.
Why should I use a password generator instead of creating my own?
Humans are predictable. Common patterns like capitalizing the first letter, adding a number at the end, or using a ! at the end are well-known to attackers. A random password generator removes all human bias and creates passwords with maximum entropy — meaning each character is equally likely to appear in any position, making the password exponentially harder to crack.
