Password Generator
Generate cryptographically secure passwords with customizable length and character types.
Configure options below
Features
Everything you need to create strong, unique passwords.
Cryptographic Randomness
Uses crypto.getRandomValues() for true cryptographic-quality random number generation, not predictable Math.random().
Customizable Options
Control password length (8-128), character types, and ambiguous character exclusion to match any password policy.
Strength Analysis
Real-time strength indicator evaluates your password based on length and character diversity with a visual bar.
Batch Generation
Generate 5 passwords at once and pick the one you like best. Each has its own copy button for convenience.
How It Works
Three simple steps to generate a strong password.
Configure Options
Set your desired password length using the slider and select which character types to include (uppercase, lowercase, numbers, symbols).
Generate Password
Click Generate for a single password or Generate 5 for multiple options. Each password uses cryptographic randomness.
Copy & Use
Click the copy button to copy your password to the clipboard. Use it immediately in your account registration or password manager.

Frequently Asked Questions
Common questions about password security and generation.
Why should I use a password generator instead of making up passwords?
Humans are predictable when creating passwords, often using common words, dates, and patterns that attackers can guess. A password generator uses cryptographic randomness to create truly unpredictable passwords that resist brute-force attacks, dictionary attacks, and social engineering.
What makes a password strong?
Password strength depends on two factors: length and character diversity. A strong password is at least 16 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. Each additional character type and length increase makes the password exponentially harder to crack.
Is crypto.getRandomValues() actually secure?
Yes. crypto.getRandomValues() is a Web Crypto API that uses the operating system's cryptographically secure pseudo-random number generator (CSPRNG). Unlike Math.random(), it produces values suitable for security purposes and is used in production security applications worldwide.
Does this tool store or transmit my generated passwords?
No. Your generated passwords are never sent to any server, stored in any database, or logged anywhere. Once you navigate away from the page, the generated passwords exist only if you copied them.
