Password Generator
Generate secure, random passwords with customizable options. 100% private - all generation happens in your browser using cryptographic security.
Cryptographically Secure
Uses crypto.getRandomValues() for true randomness and maximum security.
100% Private
All generation happens in your browser. Passwords never leave your device.
Fully Customizable
Control length, character types, and generate up to 20 passwords at once.
Password Security Best Practices
Use at least 16 characters
Longer passwords are exponentially harder to crack. 16+ characters provides excellent security.
Use all character types
Include uppercase, lowercase, numbers, and symbols for maximum strength.
Never reuse passwords
Use a unique password for each account. Consider using a password manager.
Enable two-factor authentication
Even with a strong password, add 2FA for an extra layer of security.
Frequently Asked Questions
How secure are the generated passwords?
Our password generator uses crypto.getRandomValues(), a cryptographically secure random number generator built into modern browsers. This ensures your passwords are truly random and secure, meeting the highest security standards.
What is the recommended password length?
We recommend at least 16 characters for strong security. Longer passwords (20-32 characters) provide even better protection against brute-force attacks. The tool supports up to 128 characters for maximum security.
What does “exclude ambiguous characters” mean?
This option removes characters that look similar and can be easily confused, such as 0 (zero) and O (letter O), 1 (one) and l (letter L), and I (letter i). This is helpful when typing passwords manually or sharing them verbally.
Are my passwords stored or sent anywhere?
No. All password generation happens entirely in your browser. Your passwords are never sent to any server or stored anywhere. They exist only in your browser's memory until you close the page.
How many passwords can I generate at once?
You can generate between 1 and 20 passwords at a time. This is useful when you need to create multiple accounts or want to choose from several options.
What do the password strength indicators mean?
Strength is calculated based on password length and character diversity (entropy). Weak: <40 bits, Medium: 40-59 bits, Strong: 60-79 bits, Very Strong: 80+ bits of entropy. Higher entropy means more possible combinations and better security.
