Get code to generate a password

Instead of generating a password directly, this tool gives you code to generate a password. This means that you can see exactly how the password is generated, and don't need to trust this tool not to steal your password.

If you don't mind long passwords and don't care what special characters are included, you can run openssl rand -base64 16 to get a secure password. This is the easiest to verify as trustworthy, so this is a very good choice.
