Password Generator

A strong password is long, random, and unique to each account. Most people know this, but generating, remembering, and managing dozens of truly random passwords is impractical without tools. Password managers handle storage; this tool handles generation. Using the Web Crypto API's crypto.getRandomValues() function, the same cryptographically secure randomness used in professional security tools, this generator produces passwords that are computationally impractical to predict, guess, or brute-force when used at sufficient length.

How to use

1. Set the password length. Drag the slider or type a number. 16 characters is a reasonable minimum for most services. 24–32 characters is appropriate for high-security accounts like email, banking, and work accounts. Password managers can handle any length, so longer is always better.
2. Choose your character sets. Check the boxes for uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*). For maximum strength, use all four. Disable symbols if the target service rejects certain special characters.
3. Generate. Click Generate or reload to get a new random password. Each click produces an entirely new, independent random sequence, there's no pattern or relationship between consecutive generated passwords.
4. Copy and use. Click Copy to copy the password to your clipboard. Paste it directly into your password manager's new password field. Never type generated passwords manually, even slight transcription errors make them unusable.

Tips for best results

• Use a password manager. A generated password is only useful if you can retrieve it later. Copy the generated password directly into a password manager (1Password, Bitwarden, Dashlane, iCloud Keychain) before using it anywhere. Never store passwords in notes apps, spreadsheets, or plain text files.
• Use different passwords for every account. The main purpose of a password generator is to make it practical to have completely different, unguessable passwords everywhere. If one site is breached, unique passwords prevent attackers from using that password to access your other accounts (credential stuffing).
• Longer is more important than complex. A 20-character password with only lowercase letters is harder to crack than a 10-character password with all character types. If a site limits you to 12 characters, use all four character types. If it allows 32+, length matters more than complexity.
• For API keys and tokens, use Base64. For developer use cases like generating API keys, session tokens, or random secrets, the Base64 tool can encode random byte strings into safe ASCII for use in configuration files.

Why use PixMidas

• Cryptographically secure randomness. Generated passwords use crypto.getRandomValues() from the Web Crypto API, not Math.random(), which is pseudorandom and unsuitable for security. The randomness is equivalent to professional security tools.
• 100% private. The generated password is created entirely on your device. It is never transmitted to any server, never logged, and never stored anywhere outside your clipboard after you copy it.
• No account needed. Free and instant, no signup required. Passwords are created entirely on your device.

Frequently asked questions

How long should my password be?

The minimum for any meaningful security is 12 characters. 16 characters is a good default. For email, banking, and work accounts: 20–24 characters. For accounts that support it and where you use a password manager: 32 characters or more. At 20 characters with mixed case, numbers, and symbols, the search space is 95^20 ≈ 3.6 × 10^39, far beyond what any current or near-future computing technology can brute-force.

What makes a password "strong"?

Strength comes from length and randomness. A password is strong when an attacker cannot predict or enumerate it within any reasonable timeframe. This means: it must be generated by a cryptographically secure random source (not predictable patterns), it must be long enough that exhaustive search is computationally infeasible, and it must be unique to each account so a breach of one doesn't expose others. Memorable passwords, even complex-looking ones, are almost always weaker than randomly generated ones of the same length.

Is it safe to generate passwords in a browser?

Yes, when the generator uses crypto.getRandomValues() as this tool does. The Web Crypto API provides OS-level cryptographic randomness, the same source used by desktop security tools. The generated password never leaves your device and is cleared from memory when you navigate away. The only potential exposure point is your clipboard, paste and clear your clipboard after storing the password in your password manager.

Why should I use a password generator instead of creating my own?

Human-created passwords are not random. People systematically favor certain characters, patterns, dictionary words, and substitutions (3 for e, @ for a, etc.). These patterns are well-known to attackers. A well-trained GPU can test billions of human-pattern-based guesses per second. A truly random 20-character password, by contrast, has no discoverable pattern and cannot be cracked by any known technique within a human lifetime.

What if the site doesn't accept certain characters?

Some older systems reject specific symbols or have a limited allowed character set. If your generated password gets rejected, disable the Symbols checkbox and regenerate. For systems that reject all special characters, increase the length to compensate, a 24-character alphanumeric password is still extremely strong.

Should I use this for generating API keys or tokens?

For application secrets, API keys, and cryptographic tokens, you typically want more control over the encoding format. The output of this generator is suitable as a password. For secrets that need to be URL-safe, hex-encoded, or base64-encoded, use a code-level random byte generator (like Node.js crypto.randomBytes()) or the Base64 tool to encode a random binary input.
