ToolsSoup's Random Password Generator creates strong, unique, and secure passwords right in your browser. Choose the length and character types, generate one or many passwords at once, and copy them with a single click. Everything runs locally using your device's cryptographically secure random generator — no passwords are ever sent to a server, logged, or stored.

      

        
What is a random password generator?

        
A random password generator is a tool that builds unpredictable passwords from a mix of uppercase letters, lowercase letters, numbers, and symbols. Unlike a password you make up yourself, a randomly generated one has no pattern, name, or dictionary word for an attacker to guess. This tool uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure source browsers use for encryption, so every password is genuinely random and hard to crack.

        
      

      

        
How to generate a strong password

        
Creating a secure password takes just a few seconds:

        
  1. Set the length with the slider — 16 characters or more is recommended for important accounts.
  2. Pick which character types to include: uppercase, lowercase, numbers, and symbols.
  3. Optionally exclude look-alike characters such as l, 1, I, O, and 0 to avoid typos.
  4. Click Generate, then copy your new password and store it in a password manager.

      

      

        
What makes a password strong?

        
Password strength comes down to length and randomness. A longer password drawn from a larger pool of character types has far more possible combinations, which dramatically increases the time needed to crack it. The strength meter on this page estimates entropy in bits from your chosen length and character set: aim for the Strong rating, use a different password for every account, and never reuse passwords across sites.

Frequently asked questions

        

          
Are these passwords safe to use?

          
Yes. Passwords are generated locally in your browser with the Web Crypto API, a cryptographically secure random source. Nothing is sent over the network, so no one — including ToolsSoup — ever sees the passwords you create.

        

        

          
How long should my password be?

          
For most accounts, 16 characters or more is a good target. Longer passwords with a mix of character types are exponentially harder to crack. For highly sensitive accounts, consider 20+ characters.

        

        

          
Is it really random?

          
Yes. The generator uses crypto.getRandomValues, the same cryptographically secure randomness browsers use for encryption keys, and applies rejection sampling so every character is unbiased.

        

        

          
Why should I exclude similar characters?

          
Characters like the lowercase L, the number 1, the capital I, the letter O, and the number 0 can be easy to confuse when reading or typing a password by hand. Excluding them helps prevent mistakes, though it slightly reduces the character pool.

        

        

          
Should I save these passwords somewhere?

          
Use a reputable password manager to store the passwords you generate. Avoid writing them in plain text files or reusing the same password across multiple sites.
