How secure is this password generator?
Our password generator is completely secure and private. All passwords are generated locally in your browser using cryptographically secure random number generation (Web Crypto API). No passwords are ever sent to our servers or stored anywhere. Your privacy is our top priority.
What makes a strong password?
A strong password should be at least 12-16 characters long, include a mix of uppercase and lowercase letters, numbers, and symbols. It should avoid common words, personal information, and predictable patterns. Our strength meter provides real-time feedback to help you create secure passwords.
What is the difference between random passwords and passphrases?
Random passwords are completely random character sequences that are highly secure but harder to remember. Passphrases combine multiple words with separators, making them easier to remember while still maintaining good security. Passphrases are recommended for accounts you need to remember, while random passwords are better for password managers.
How long should my password be?
For maximum security, use passwords that are at least 16 characters long. However, 12 characters is generally considered the minimum for strong passwords. Longer passwords (20+ characters) provide even better security, especially when combined with various character types.
Should I exclude similar characters?
Excluding similar characters (like i, l, 1, L, o, 0, O) can help avoid confusion when manually typing passwords. However, this slightly reduces the character pool. For passwords stored in password managers, you can keep all characters for maximum security. For passwords you type frequently, excluding similar characters may be helpful.
Can I generate multiple passwords at once?
Yes! You can generate up to 50 passwords at once. This is useful for creating passwords for multiple accounts, testing purposes, or bulk password generation. All passwords can be copied individually or downloaded as a text file.
Is it safe to use generated passwords?
Absolutely! Our password generator uses cryptographically secure random number generation, making the passwords truly random and unpredictable. The passwords generated are as secure as those from any professional password manager. However, always ensure you store them securely using a trusted password manager.
What character sets should I include?
For maximum security, include all character sets: uppercase letters, lowercase letters, numbers, and symbols. This maximizes the possible character combinations and makes brute-force attacks significantly more difficult. The more character types you include, the stronger your password will be.
Can I use this for business or enterprise accounts?
Yes, our password generator is suitable for personal, business, and enterprise use. The passwords generated meet industry security standards. However, always follow your organization's password policies and consider using a password manager for enterprise environments.
Do you store or track the passwords I generate?
No, we never store, track, or transmit any passwords. All password generation happens entirely in your browser using JavaScript. We have no access to the passwords you generate, and they never leave your device. This ensures complete privacy and security.
