Free secure password generator
This free password generator creates strong, random passwords entirely in your browser. No passwords are ever sent to a server, logged, or stored anywhere. Every password is generated fresh using crypto.getRandomValues() — the same cryptographic randomness used in SSL certificates and encryption keys — making each password genuinely unpredictable.
How to create a strong password
The most important factor in password strength is length. A 16-character random password is dramatically more secure than an 8-character one, even if both include symbols and numbers. For most accounts, aim for at least 12 characters. For important accounts like email, banking, and work systems, use 16 to 20 characters or more.
The second factor is randomness. A password like "P@ssw0rd1" is technically complex but follows a predictable pattern that attackers try early. A truly random password generated by this tool has no patterns to exploit.
The third factor is uniqueness. Never reuse a password across multiple sites. If one site is breached, attackers will immediately try your credentials elsewhere — a practice called credential stuffing. Use a different randomly generated password for every account.
How to store your passwords
A password manager is the best solution. Recommended options include Bitwarden (free and open source), 1Password, Apple Keychain (built into iPhone and Mac), or Google Password Manager (built into Chrome and Android). These tools encrypt your passwords and sync them across your devices so you only need to remember one master password.
Understanding the strength meter
The strength meter calculates password entropy — measured in bits. A 16-character password using all character types has over 100 bits of entropy. The meter rates passwords as Weak (under 50 bits), Fair (50 to 80 bits), Strong (80 to 128 bits), or Very Strong (128 or more bits).
How long should my password be?
At least 12 characters for general accounts. Use 16 to 20 characters for important accounts like email, banking, and work systems. Your password manager master password should be at least 20 characters.
Are these passwords safe to use?
Yes. Passwords are generated locally in your browser and are never transmitted to any server. We have no way of knowing what password was generated.
Should I use a password manager?
Strongly recommended. Bitwarden is free, open source, and widely recommended. Apple Keychain and Google Password Manager are built into their ecosystems at no cost.
What makes a password strong?
Length (12 or more characters), randomness (no dictionary words), and variety (uppercase, lowercase, numbers, and symbols). This generator maximises all four by default.
Can I use these passwords right now?
Yes — generate a password, click Copy, and paste it into your account's password field. Save it in a password manager before navigating away.
