Free Online Password Generator
Generate a strong, random password with custom length and character types — created locally in your browser using a cryptographically secure generator.
How to use the password Generator
- Set your desired password length.
- Choose which character types to include: uppercase, lowercase, numbers, symbols.
- Optionally exclude ambiguous characters that look similar, like l, 1, O and 0.
- Click 'Generate password' and copy the result.
Example
Generating a 16-character password with all character types enabled might produce something like Xk9#mQ2vL8pR!wZ4 — unique every time.
Why use a random password generator?
Passwords that are short, predictable, or reused across accounts are one of the most common security weaknesses. A long, random password generated fresh for each account is far harder to guess or crack.
Cryptographically secure generation
This tool uses the Web Crypto API's secure random number generator, not Math.random(), so the resulting passwords are suitable for real account security rather than just appearing random.
Frequently asked questions
Longer is generally stronger; 16 characters or more with a mix of character types is a solid baseline for most accounts.
No, each password is generated locally in your browser and never transmitted or saved.
Enable that option if you'll need to type the password manually and want to avoid confusing similar-looking characters like l, 1, O and 0.
No, always use a unique password per account, and consider a password manager to store them securely.
