How to use this tool

2. Select the character types to include, such as lowercase letters, uppercase letters, numbers, and symbols.
3. Generate the password in your browser.
4. Copy the result and save it in your password manager.

Step by step, what happens

1. The tool reads your selected length and character options from the page controls.
2. It builds an allowed character set from the options you chose.
3. It uses your browser's cryptographically secure random generator to pick characters from that set.
4. It returns a new password that stays in your browser and is not sent to a server.

Worked example

If you want a new account password for an admin login, you can generate one with mixed character types and a longer length.

Input: length 16, lowercase, uppercase, numbers, symbols

1. Set the length to 16 and turn on lowercase letters, uppercase letters, numbers, and symbols.
2. Generate the password so the tool can choose 16 random characters from the allowed set.

Tips and common mistakes

• Use a longer length for important accounts, especially if symbols are allowed.
• Do not disable too many character types unless a system you use has a strict password rule.
• If you need to type the password manually, avoid symbols that are easy to confuse with other characters.
• Store the generated password in a password manager instead of reusing it elsewhere.
