Random Password Generator
A random password generator that allows you to customize password length and complexity. You can generate secure passwords containing lowercase letters, uppercase letters, numbers, and symbols.
- Set password length (4-64 characters)
- Choose to include lowercase, uppercase, numbers, and symbols
- Generate multiple passwords at once (up to 100)
- Exclude specific characters that may cause confusion (e.g. 0, O, l, I)
- One-click copy of generated password
- Safe: Passwords are generated locally and not stored
You can set the password length between 4 and 64 characters. Shorter passwords are easier to remember but less secure, while longer passwords provide better security but can be harder to type. For most accounts, a password length of 12-16 characters is recommended.
The generator allows you to choose which types of characters to include in your passwords:
- Lowercase letters (a-z): The most basic characters, included by default
- Uppercase letters (A-Z): Adding these increases password complexity
- Numbers (0-9): Numerical characters that add another layer of complexity
- Symbols (!@#$%^&* etc.): Special characters that significantly increase password strength
You can generate up to 100 passwords at once, which is useful when setting up multiple accounts or when you want to choose the most memorable password from a selection.
The tool includes a feature to exclude specific characters that are often confused with one another, such as 0 and O, or 1, l, and I. By default, these characters are excluded to reduce the chance of input errors. You can customize this list based on your needs.
A strong password typically has the following characteristics:
- Length: At least 12 characters long
- Complexity: Uses a mix of character types (lowercase, uppercase, numbers, symbols)
- Unpredictability: Avoids dictionary words, names, dates, or other easily guessed information
- Uniqueness: Not used for any other account
- Use unique passwords for each account: If one password is compromised, others remain safe
- Change passwords regularly: Especially for sensitive accounts
- Use a password manager: To securely store and manage your passwords
- Enable two-factor authentication: Adds an extra layer of security beyond passwords
- Select the desired password length (4-64 characters).
- Choose how many passwords to generate (1-100).
- Select the character types to include (lowercase, uppercase, numbers, symbols).
- Optionally modify the list of characters to exclude.
- Click "Generate" to create your random password(s).
- Review the generated passwords and select the one you want to use.
- Use the copy button to copy the password for use in account registration or password changes.
Our password generator uses JavaScript's built-in Math.random() function to ensure true randomness. The generation process happens entirely in your browser, meaning your passwords never leave your device and are not transmitted over the internet.
- All password generation occurs locally in your browser
- No passwords are stored, saved, or transmitted
- The source code is open and can be reviewed for transparency
- Each password is generated using cryptographically secure randomization methods
When registering for new online services, use this tool to generate a strong, unique password that you haven't used elsewhere.
Regularly updating your passwords is a good security practice. Generate new passwords for your important accounts every few months.
Generate multiple passwords at once for use by a team or family, ensuring each person has a unique but strong password.
While our tool generates completely random passwords for maximum security, sometimes you need a password you can remember:
- Take the first letter of each word in a sentence
- Combine unrelated words with numbers and symbols
- Use a passphrase that's long but meaningful to you
- Personal information (names, birthdays, addresses)
- Dictionary words or common phrases
- Sequential characters (123456, abcdef)
- Repeated characters (aaaaaa, 111111)
- Keyboard patterns (qwerty, asdfgh)
Please keep your generated password safe. This tool does not store any generated passwords. For maximum security, consider using a reputable password manager to store and manage your passwords.
