Create strong 12-character passwords with our secure random password generator. Built for optimal security and convenience.
Frequently Asked Questions About Password Security
Why is a 12-character password recommended?
A 12-character password is the current sweet spot between security and memorability. It provides excellent protection against brute force attacks while still being manageable for users. When combined with a mix of character types (uppercase, lowercase, numbers, and symbols), a 12-character password can take centuries to crack using current technology. This length satisfies most security requirements for online services while remaining practical for everyday use.
How secure are the passwords generated by this tool?
The passwords created by our generator use cryptographically secure random number generation in your browser. Each character is chosen randomly from your selected character sets. With the default settings (12 characters including uppercase, lowercase, numbers, and symbols), the passwords have high entropy and are extremely difficult to crack through brute force methods. Our algorithm creates passwords with approximately 72 bits of entropy with default settings, which would require trillions of years to crack with current computing technology.
How should I store my passwords securely?
For best security practices:
- Use unique passwords: Create a different password for each account
- Use a password manager: Store your passwords in a reputable password manager like LastPass, 1Password, or Bitwarden
- Enable two-factor authentication (2FA): Add an extra layer of security whenever possible
- Update regularly: Change important passwords periodically, especially after security breaches
- Maintain privacy: Never share your passwords or write them down in plain text
- Check for breaches: Use services like HaveIBeenPwned to check if your accounts have been compromised
What makes a password strong?
A strong password has several key characteristics:
- Length: Longer passwords are exponentially harder to crack (12+ characters recommended)
- Complexity: Mix of uppercase letters, lowercase letters, numbers, and special symbols
- Unpredictability: Avoid common patterns, dictionary words, or personal information
- Uniqueness: Different from passwords used on other sites or services
- Randomness: Truly random passwords are much stronger than human-created patterns
Our password generator ensures all these characteristics are incorporated into every password it creates.
Is my generated password stored or sent anywhere?
No. All password generation takes place entirely within your browser. Your generated passwords are never transmitted over the internet, stored on our servers, or logged in any way. The entire process happens locally on your device, ensuring complete privacy and security. You can even use our generator offline once the page has loaded.
How do I create a memorable but secure password?
While randomly generated passwords are the most secure, if you need to create a memorable strong password:
- Start with a phrase or sentence that's meaningful to you
- Convert it to an acronym using the first letter of each word
- Replace some letters with numbers or symbols (e.g., 'a' with '@', 's' with '$')
- Add some capitalization
- Include a number that's significant to you but not obvious (like your birth year)
For example, "I love hiking in Colorado every summer since 2015!" could become "IlhiCes2015!".
However, for critical accounts, a randomly generated password stored in a password manager is always the safest option.
