Create strong, random passwords using this browser-based generator that runs entirely offline for maximum security. Set password length from 6 to 99 characters, choose which character types to include—lowercase, uppercase, numbers, symbols—or add your own custom characters. Generate up to 20 unique passwords at once, each guaranteed to contain at least one character from every selected type. The strength indicator shows password quality based on length and character variety. Every password uses crypto.getRandomValues() for true randomness, not pseudo-random generation. No data leaves your browser during the process.
This tool creates cryptographically secure random passwords directly in your browser. Configure length, character types, and quantity to match your security needs.
The password count setting generates 1-20 passwords at once. Create multiple passwords when setting up several accounts or when you want options. Each password receives the same randomness level regardless of how many you generate. For length, choose between 6 and 99 characters. A minimum of 12 characters works for most accounts. Use 16 or more for banking, email, and other sensitive accounts. Some websites limit password length—check requirements before generating. If a site accepts long passwords, use them since extra length adds significant security at no cost.
Check boxes for lowercase letters (a-z), uppercase letters (A-Z), numbers (0-9), and symbols (!@#$%^&*). Most websites accept all four types, so select them all unless you know a site has restrictions. The generator ensures at least one character from each selected type appears in every password, preventing the rare case where random selection skips a type entirely. Combining all four types gives each character position about 94 possibilities instead of 26, dramatically multiplying total combinations.
Some websites restrict which symbols you can use or require specific characters. Enable the custom characters option and type exactly what you need. If a site only allows !@#$, enter those characters. The generator includes your custom characters alongside standard types you select. This feature also helps when you want specific elements mixed with random characters—add a few letters or numbers, and the generator blends them throughout the password.
Each password has a copy button that places it on your clipboard. Click to copy, then paste directly into your account setup. The "Copy All" button copies all passwords separated by line breaks—useful when transferring to a password manager. After copying and pasting, store passwords in a dedicated password manager like Bitwarden, 1Password, or your browser's built-in storage. Never save passwords in plain text files, emails, or notes apps where others can access them.
Colored bars below each password show relative strength based on length and character variety. Weak passwords are under 8 characters or use one character type. Medium passwords are 8-11 characters with two or three types. Strong passwords are 12-15 characters with three or four types. Very strong passwords have 16+ characters with all four types. An 8-character password using all character types beats a 12-character password with only lowercase letters.
Banking and financial accounts deserve 16-20 characters with all four types. Generate a unique password for each institution—never reuse financial passwords. Your email account controls password resets for other accounts, so protect it with 16+ characters. Social media accounts contain personal information valuable for identity theft—use 12-16 characters with at least three types. WiFi passwords protect your entire network, so use 16+ characters since you typically enter them only once per device.
This generator runs entirely in your browser using crypto.getRandomValues(), which draws from your operating system's random number generator. This produces true randomness suitable for security—not the predictable pseudo-randomness of Math.random(). No data leaves your browser during generation. Your passwords never travel across the internet, get stored in a database, or appear in logs. You can verify this by disconnecting your internet after loading the page—the generator continues working. Once you copy a password and close or refresh the page, it disappears from browser memory and exists only where you pasted it.
Never reuse passwords across accounts. When one site suffers a breach, attackers test those credentials elsewhere. Use the password exactly as generated—modifying characters to make it memorable defeats the purpose of random generation. If you need something specific, use the custom characters feature instead. Enable two-factor authentication on every account that offers it, especially email and banking. Even the strongest password provides only one factor—2FA adds a second requirement that blocks attackers who obtain your password through breaches.
