Generated locally in your browser using crypto.getRandomValues(). No data is sent to any server.

Generate cryptographically secure passwords directly in your browser with CENTERDOCK's offline password generator. Unlike online generators that may log or transmit your passwords, this tool runs 100% locally using your Random Number Generator technology — unlike many other free online tools, it's perfect for crypto wallets, banking, and high-security accounts.

Choose from three generation modes: random passwords with customizable character sets, passphrases using random words that are easier to remember, or pronounceable passwords that balance security with memorability. Each password displays its entropy score so you know exactly how secure it is.

Three Password Generation Modes

Random Password

The classic approach: a mix of uppercase, lowercase, numbers, and special characters. This mode produces maximum entropy per character, making it ideal when you need the strongest possible password for a given length. Customizable length from 8 to 128 characters. For mathematical randomness, check our Scientific Calculator.

Passphrase

Generate a sequence of random words separated by hyphens or spaces. Passphrases like "crystal-mountain-seven-echo-delta" are easier to remember than random characters but still extremely secure. Each word adds approximately 11-12 bits of entropy.

Pronounceable

Creates passwords that follow phonetic patterns, making them easier to type and remember while still being random. Examples: "Zopex4Nuka!" or "Mivat7Kel". Great for passwords you might need to enter manually.

Why Offline Password Generation Matters

Many password generators are web-based and could theoretically log the passwords they create. Our generator is different:

  • Runs in your browser — All code executes locally, never on a server
  • Uses crypto.getRandomValues() — The most secure randomness available in browsers
  • Works offline — Once loaded, no internet connection is needed
  • No data transmission — Zero network requests during password generation
  • Open algorithm — You can inspect exactly how passwords are created

Understanding Password Strength & Entropy

Entropy measures how many guesses an attacker would need to crack your password:

  • 40-50 bits — Acceptable for low-security accounts
  • 50-60 bits — Good for most online accounts
  • 60-80 bits — Strong, suitable for important accounts
  • 80+ bits — Excellent, recommended for crypto wallets and banking
  • 128+ bits — Maximum security, effectively uncrackable

Our generator displays entropy for every password, plus an estimated time-to-crack based on current computing capabilities. Use this information to choose passwords appropriate for each security context.
