Free Online Password Generator — Cryptographically Secure & Private
Our free password generator uses your browser's built-in crypto.getRandomValues() API — the same cryptographic standard used by professional security tools. Unlike tools that rely on Math.random(), our generator produces truly unpredictable passwords. Every password is created locally in your browser and never sent to any server.
Choose between random passwords (maximum security with mixed characters) or memorable passphrases (random words joined by hyphens, perfect for master passwords). The real-time strength meter and time-to-crack estimate give you instant feedback on how secure your password really is against modern GPU-based attacks.
How to Generate a Strong Random Password Online Free
- Choose between Random Password (most secure) or Passphrase (memorable) mode.
- Set the password length using the slider — 16+ characters is recommended for important accounts.
- Select character types: uppercase, lowercase, numbers, and symbols. Enable all four for maximum strength.
- Optionally choose bulk mode (5 or 10 at once) to generate multiple unique passwords simultaneously.
- Click "Generate Password", then copy or download your secure password.
Secure Password Maker with Strength Meter – Key Features
Cryptographically Secure Generation
Uses the browser's crypto.getRandomValues() API — the same standard used by security professionals. Far more secure than Math.random() or pseudo-random number generators.
Real-time Strength Meter & Crack Time
Instant visual feedback shows your password strength from Very Weak to Very Strong. The time-to-crack estimate shows how long a modern GPU cluster would take to brute-force it.
Passphrase Mode for Master Passwords
Generate memorable word-based passphrases (e.g. 'tiger-castle-river-lamp') that are easy to type and remember while still being highly secure — ideal for password manager master passwords.
Bulk Generation & Download
Generate 5 or 10 unique passwords at once. Copy them individually or all together, and download the full list as a .txt file for offline use.

Yes. Our tool uses the browser's crypto.getRandomValues() API which produces cryptographically secure random numbers. Passwords are generated entirely in your browser and are never transmitted to any server.
A passphrase is a string of random words separated by hyphens (e.g. 'tiger-castle-river-lamp'). Use passphrases for master passwords — they are easier to remember and type while still being highly secure against brute-force attacks.
A minimum of 12 characters for standard accounts. For high-security accounts like banking, email, or crypto wallets, use 16–20+ characters with a mix of uppercase, lowercase, numbers, and symbols.
Yes. Select '5 at once' or '10 at once' in the Generate Mode section before clicking Generate. All passwords will appear in a list that you can copy individually or download as a text file.
