Password Generator — Create Strong, Secure Passwords
A strong password is your first line of defense against unauthorized access to your online accounts. Yet millions of people still use weak, guessable passwords like 123456, password, or qwerty — passwords that hackers can crack in seconds using dictionary attacks and brute-force techniques. In fact, the most commonly used passwords can be broken instantly, putting your email, banking, social media, and personal data at serious risk.
Password security comes down to three factors: length (longer passwords are exponentially harder to crack), complexity (mixing uppercase, lowercase, numbers, and symbols), and uniqueness (using a different password for every account). A 12-character password with mixed characters has trillions of possible combinations — far beyond what even powerful computers can brute-force in a reasonable time.
Our free password generator creates cryptographically random passwords based on your chosen settings. Select the length, enable the character types you need, and optionally exclude ambiguous characters that are easy to misread (like 0, O, I, and l). The built-in strength meter gives you real-time feedback on your password's security level.
How to Use the Password Generator
-
Set the password length Drag the slider to choose a length between 8 and 64 characters. Longer passwords are more secure — we recommend at least 16 characters for strong protection.
-
Choose character types Check the boxes for the character sets you want to include: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*). Using all types maximizes password strength.
-
Exclude ambiguous characters (optional) Enable the exclusion option to remove characters that look similar, such as zero and the letter O, or uppercase I and lowercase l. This makes passwords easier to read and type.
-
Generate your password Click "Generate Password" to create a random password. The password appears in the display above, and the strength meter updates to show its security level.
-
Copy and use Click the copy icon (📋) to copy the password to your clipboard. Use the refresh icon (🔄) to quickly generate a new one. Store your passwords in a password manager for safekeeping.

Frequently Asked Questions
A strong password has three key attributes: length (at least 12–16 characters), complexity (a mix of uppercase, lowercase, numbers, and symbols), and unpredictability (no dictionary words, personal info, or common patterns). Our generator ensures all three by creating truly random passwords with your chosen settings.
We recommend a minimum of 12 characters for most accounts, and 16 characters or more for sensitive accounts like email, banking, and password managers. Each additional character exponentially increases the time required to crack the password — a 20-character password with mixed characters would take billions of years to brute-force with current technology.
No, never. Using the same password across multiple accounts means that if one account is compromised, all your other accounts are immediately at risk. Always use a unique password for every account. A password manager can help you generate and store hundreds of unique passwords without having to memorize them.
Ambiguous characters are letters and numbers that look similar to each other, such as 0 (zero) and O (letter O), or I (uppercase i) and l (lowercase L). If you'll be reading or typing the password manually, excluding these characters reduces confusion. If you're using a password manager (which we recommend), you can safely include them.
Yes. The generator uses JavaScript's crypto.getRandomValues() API, which is cryptographically secure and designed specifically for security-sensitive applications. This is the same underlying technology used by web browsers for encryption — far more secure than the basic Math.random() function, which should never be used for password generation.
Never store passwords in plain text files, sticky notes, or unencrypted documents. We strongly recommend using a password manager like Bitwarden, 1Password, or Apple Keychain. These tools encrypt your passwords and sync them across your devices. Many password managers also include built-in generators and auto-fill features that make using strong passwords effortless.
