Your Secure Password
About Password Security
In today's digital world, strong password security is essential to protect your online accounts from unauthorized access. Our free online password generator helps you create secure, random passwords that are resistant to brute force attacks and password cracking techniques.
Why Strong Passwords Matter
Prevent Brute Force Attacks
Weak passwords can be cracked in seconds using automated tools. A 12-character password with mixed character types would take centuries to crack.
Protect Against Data Breaches
When services are compromised, strong passwords prevent hackers from accessing your other accounts through credential stuffing attacks.
Secure Sensitive Information
Banking, email, and social media accounts require extra protection as they often serve as gateways to your digital identity.
Meet Compliance Requirements
Many industries require strong password policies to comply with security standards like PCI DSS, HIPAA, and GDPR.
Password Security Metrics Explained
Password Length
The most important factor in password strength. Each additional character exponentially increases the possible combinations. We recommend passwords of at least 12 characters for general use and 16+ for sensitive accounts.
Character Diversity
Using multiple character types (uppercase, lowercase, numbers, symbols) significantly increases the possible combinations. Our tool ensures your password includes all selected character types.
Entropy
Measured in bits, entropy quantifies the unpredictability of your password. Higher entropy means more security. A password with 80+ bits of entropy is considered very strong for most purposes.
Avoiding Predictability
Our generator avoids common patterns, sequential characters, and dictionary words that make passwords vulnerable to cracking.

Password Security Best Practices
- Use unique passwords for every account to prevent domino-effect breaches
- Never reuse passwords across different services
- Use a password manager to store and organize your passwords securely
- Enable two-factor authentication (2FA) whenever available
- Change passwords immediately if a service reports a breach
- Avoid personal information like names, birthdays, or common words
- Consider passphrases for services that allow long passwords (20+ characters)
Frequently Asked Questions
What makes a password strong?
A strong password is long (12+ characters), uses multiple character types, doesn't contain dictionary words or personal information, and is completely random. Our generator creates passwords that meet all these criteria.
How often should I change my passwords?
Current best practices recommend changing passwords only when there's evidence of compromise, unless compliance requirements dictate otherwise. Focus on creating strong, unique passwords rather than frequent changes.
Are generated passwords stored anywhere?
No. All password generation happens in your browser - your passwords never leave your device or touch our servers. For maximum security, we recommend generating passwords offline when possible.
Can I use this for my company's password policy?
Yes, our generator is ideal for creating passwords that meet corporate security policies. You can customize the settings to match your organization's requirements.
What's better - random passwords or passphrases?
Random passwords (like those we generate) offer the highest security for a given length. Passphrases (multiple random words) can be easier to remember while still being secure, but need to be longer (20+ characters).
