How to Generate Secure Random Passwords Online
Weak passwords are the leading cause of account breaches and identity theft. Security experts recommend using long, random passwords with a mix of letters, numbers, and symbols — but creating truly random passwords manually is difficult. This guide shows you how to generate secure random passwords using fixie.tools — a free online password generator that creates cryptographically strong passwords, no signup required, running entirely in your browser for privacy.
Step 1: Open the Password Generator
Navigate to fixie.tools/password in your web browser. The tool runs entirely in your browser using cryptographically secure random number generation, meaning your passwords are never sent to any server. No account creation or registration is required.
Step 2: Choose Password Length
Set your desired password length using the slider. Security experts recommend at least 16 characters for most accounts, and 20+ characters for critical accounts like email, banking, or password managers. Longer passwords are exponentially harder to crack. The tool supports passwords from 8 to 128 characters.
Step 3: Select Character Types
Choose which character types to include in your password. Options include uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special symbols (!@#$%^&*). Including all character types creates the strongest passwords. However, if a website restricts certain characters, uncheck those options. The tool displays the entropy (strength) of your password configuration in bits.
Step 4: Generate Your Password
Click the generate button to create a random password matching your specifications. The tool uses the browser's Web Crypto API (window.crypto) to ensure true randomness rather than predictable pseudo-random generation. You can generate multiple passwords and compare them to pick one you prefer.
Step 5: Copy and Use Your Password
Click the copy button to copy your new password to the clipboard. Immediately paste it into your password manager (like 1Password, Bitwarden, or LastPass) to save it securely. Never write passwords on paper or store them in plain text files. If you don't use a password manager, consider using one — they're the safest way to manage strong, unique passwords for every account.
