What Makes a Strong Password?
A strong password is your first line of defense against unauthorized access to your accounts. A secure password should have:
- Sufficient Length: At least 12-16 characters (longer is better)
- Character Variety: Mix of uppercase, lowercase, numbers, and symbols
- Randomness: Avoid predictable patterns, dictionary words, or personal information
- Uniqueness: Different password for each account
This tool uses cryptographically secure random number generation to create truly random passwords that are difficult to guess or crack.
Password Best Practices
Use Long Passwords
Longer passwords are exponentially harder to crack. Aim for at least 16 characters for important accounts. Each additional character significantly increases security.
Include Character Variety
Use a mix of uppercase letters, lowercase letters, numbers, and symbols. This increases the possible character combinations and makes brute-force attacks much more difficult.
Avoid Common Patterns
Don't use dictionary words, common phrases, keyboard patterns (like "qwerty"), or personal information (names, birthdays, addresses). These are easily guessed by attackers.
Use Unique Passwords
Never reuse passwords across multiple accounts. If one account is compromised, all your accounts with the same password become vulnerable. Use a password manager to keep track of unique passwords.
Enable Two-Factor Authentication
Even with a strong password, enable two-factor authentication (2FA) whenever possible. This adds an extra layer of security by requiring a second verification method.
Security Considerations
This password generator uses the Web Crypto API's crypto.getRandomValues() to generate cryptographically secure random numbers. This ensures:
- True Randomness: Passwords are generated using secure random number generation
- No Server Storage: All generation happens in your browser - passwords never leave your device
- No Tracking: We don't log, store, or transmit any generated passwords
- Client-Side Only: Your passwords are generated locally and never sent to our servers
Important: Always use a password manager to store your passwords securely. Never share your passwords or write them down in insecure locations.
Password Managers
Password managers are essential tools for maintaining strong, unique passwords across all your accounts. They offer:
- Secure Storage: Encrypted vault for all your passwords
- Auto-Fill: Automatically fill passwords on websites
- Password Generation: Built-in generators for creating strong passwords
- Cross-Device Sync: Access passwords on all your devices
- Security Alerts: Notifications about compromised or weak passwords
Popular password managers include 1Password, LastPass, Bitwarden, and Dashlane. Many browsers also offer built-in password managers.
Common Use Cases
- New Account Creation: Generate secure passwords when signing up for new services
- Password Updates: Create new passwords when updating existing accounts
- API Keys: Generate random strings for API keys or tokens
- Session Tokens: Create secure session identifiers
- Encryption Keys: Generate random keys for encryption purposes
- Development: Create test passwords for development and testing
Frequently Asked Questions
For most accounts, 12-16 characters is sufficient. For highly sensitive accounts (banking, email), consider 20+ characters. Longer passwords are exponentially more secure, but balance security with usability.
Yes. This tool uses the Web Crypto API's crypto.getRandomValues(), which provides cryptographically secure random number generation. This is the same
technology used by banks and security systems.
No. All password generation happens entirely in your browser. Passwords are never sent to our servers, logged, or stored anywhere. They exist only in your browser's memory until you copy or clear them.
This option excludes characters that look similar and can be easily confused: i, l, 1, L, o, 0, O. This makes passwords easier to read and type, especially when sharing verbally or writing down (though writing passwords down is not recommended).
This excludes characters that might be problematic in certain contexts: brackets, quotes, slashes, commas, semicolons, periods, and angle brackets. These characters can cause issues in URLs, command lines, or when copying/pasting into certain applications.
Modern security best practices suggest changing passwords only when there's a security breach, you suspect compromise, or the password is weak. Regular forced password changes can actually reduce security as people tend to create weaker, predictable passwords.
Yes, this tool can generate random strings suitable for API keys, tokens, or other cryptographic purposes. However, for production systems, consider using dedicated key generation tools that provide additional features like key derivation functions.
Adjust the generator settings to match the website's requirements. For example, if a site requires at least one symbol, ensure "Symbols" is enabled. If it has a maximum length, adjust the length slider accordingly.
