A password generator creates random, unpredictable strings of characters that are far more secure than anything a human would come up with. Weak and reused passwords are the leading cause of account breaches, and a single compromised credential can cascade across multiple services. Using a randomly generated password for each account is one of the simplest and most effective ways to protect your online identity.

How to Use the Password Generator
Creating strong, unique passwords for every account is one of the most important steps you can take to protect your online security. Reusing passwords or choosing predictable ones like birthdays, pet names, or simple keyboard patterns makes you vulnerable to credential stuffing attacks, where hackers use passwords leaked from one breach to access your other accounts. This password generator eliminates that risk by producing truly random strings that no human or algorithm can guess.
Step 1: Set Your Password Length
Use the length slider to choose how many characters your password should contain. The default is 16 characters, which is strong enough for most online accounts. For high-security applications like banking, email, or master passwords for a password manager, consider using 20 to 32 characters. The slider goes up to 128 characters for specialized use cases like API keys or encryption passphrases.
Step 2: Choose Character Types
Toggle the character sets you want to include: uppercase letters, lowercase letters, numbers, and symbols. Using all four types maximizes the entropy of your password, making it exponentially harder to crack. If a website restricts certain characters, you can disable specific types or edit the custom symbols field to include only the special characters the site allows.
Step 3: Adjust Optional Settings
Enable the "Exclude ambiguous characters" option if you need to read the password aloud or write it down. This removes characters that look alike in many fonts, such as zero and the letter O, the digit one and lowercase L, and uppercase I and lowercase l. You can also customize the exact set of symbols by editing the custom symbols field.
Step 4: Generate and Copy
Click "Generate New Password" to create a fresh random password. The strength meter below the password shows how resistant it is to brute-force attacks, rated from weak to very strong. When you are satisfied with the result, click the Copy button to place the password on your clipboard and paste it into your account settings or password manager. Need multiple passwords at once? Use the bulk mode to generate 5, 10, or 20 passwords in a single click, then copy them all.

FAQ
Is this password generator really free?
Yes, this password generator is completely free to use with no limits. There are no premium tiers, no signup required, and no restrictions on how many passwords you can generate. Every feature, including bulk generation and custom character sets, is available at no cost.
Are my generated passwords safe and private?
Absolutely. Every password is generated entirely in your browser using JavaScript's built-in cryptographic random number generator (crypto.getRandomValues). No passwords are ever sent to any server, stored in any database, or logged anywhere. Your passwords exist only on your screen until you copy or close the page.
What makes a password strong?
A strong password is long (at least 12-16 characters), uses a mix of uppercase letters, lowercase letters, numbers, and symbols, and avoids dictionary words or predictable patterns. Our strength meter evaluates your password based on length, character variety, and entropy to give you a clear rating from weak to very strong.
How long should my password be?
For most accounts, a password of 16 characters or more is recommended. For sensitive accounts like banking or email, aim for 20 or more characters. Longer passwords are exponentially harder to crack through brute force. Our generator supports up to 128 characters for maximum security.
What does 'exclude ambiguous characters' mean?
Ambiguous characters are letters and numbers that look similar in many fonts, such as zero (0) and the letter O, one (1) and lowercase L (l), or uppercase I (I) and lowercase l. Excluding them makes passwords easier to read and type correctly, which is especially useful when sharing passwords verbally or writing them down.
Can I generate multiple passwords at once?
Yes. Use the bulk mode feature to generate 5, 10, or 20 passwords at once. All passwords are created with the same settings you have configured, making it easy to create batches of credentials for onboarding new users, setting up test accounts, or populating a password manager.
How does the password strength meter work?
The strength meter calculates the entropy of your password based on its length and the size of the character set used. It considers whether uppercase, lowercase, numbers, and symbols are included, then estimates how resistant the password is to brute-force attacks. Passwords are rated as weak, fair, strong, or very strong based on their total entropy in bits.
