Free Online Password Generator
Our Password Generator is a free online tool designed to create strong, secure, and random passwords to help protect your online accounts. In today's digital world, using strong, unique passwords for each of your accounts is essential for maintaining your online security and privacy.
This tool runs entirely in your browser, meaning your generated passwords never leave your device. No data is sent to our servers, ensuring maximum privacy and security for your sensitive information.

Understanding Password Security
A strong password is your first line of defense against unauthorized access to your accounts. Here's what makes a password strong:
- Length - Longer passwords are generally more secure. We recommend at least 12 characters.
- Complexity - Using a mix of uppercase letters, lowercase letters, numbers, and symbols increases security.
- Randomness - Truly random passwords are harder to guess than patterns or dictionary words.
- Uniqueness - Using different passwords for different accounts limits your risk if one account is compromised.
Our password generator creates passwords with high entropy, making them extremely difficult to crack through brute force methods. For additional security in your development workflow, you can use our Hash Generator to create secure hash values for password storage.
Password Strength Explained
The strength of a password is typically measured in bits of entropy, which represents how unpredictable a password is:
- Weak (Less than 40 bits) - Could be cracked in minutes to hours.
- Fair (40-60 bits) - Would take days to months to crack.
- Good (60-80 bits) - Would take years to crack with current technology.
- Strong (80-100 bits) - Would take decades to centuries to crack.
- Very Strong (100+ bits) - Practically impossible to crack with current technology.
Our password generator's default settings create passwords with high entropy, typically in the "Very Strong" category.
Password Best Practices
Even with a strong password, it's important to follow these best practices:
- Use a Password Manager - Store your complex passwords securely in a reputable password manager.
- Enable Two-Factor Authentication (2FA) - Add an extra layer of security beyond just your password.
- Change Passwords Regularly - Update important passwords periodically, especially after security breaches.
- Don't Reuse Passwords - Use a unique password for each account to limit damage from breaches.
- Avoid Personal Information - Don't include easily guessable information like birthdays or names.
- Be Cautious of Phishing - Never enter your password on sites you reached through email links without verifying.

Frequently Asked Questions
Is this password generator secure?
Yes. Our password generator uses cryptographically secure random number generation and runs entirely in your browser. Your passwords are never transmitted over the internet or stored anywhere.
How long should my password be?
For most accounts, we recommend passwords of at least 12-16 characters. For critical accounts like banking or email, consider using 20+ characters for maximum security.
Should I include special characters?
Yes, including special characters significantly increases password strength. However, some systems have restrictions on which special characters they accept, so test your password on the target system first.
How often should I change my passwords?
Change passwords immediately if you suspect a breach. For regular maintenance, every 6-12 months is reasonable for important accounts, but focus more on using unique, strong passwords for each account.
Can I use this tool for API keys?
While this tool generates cryptographically secure random strings suitable for passwords, API keys often have specific format requirements. Check your API documentation for proper key generation methods.
