Password Generator
Generate strong, random passwords with customizable options.
A password generator creates strong, random passwords using your browser's cryptographic random source, with options for length and character types.
How to Use the Password Generator
- Choose a length. Set the password length (recommended 16+).
- Select character types. Enable at least one character set.
- Copy the password. Copy the generated password and store it securely.
This tool processes your input locally in your browser. Nothing is uploaded.
What Is Password Gen?
Strong passwords are long, random and unpredictable. A password generator creates them securely in your browser.
What makes a strong password?
Length is the most important factor. A 16-character password using multiple character types has far more possible combinations than a short one, making it much harder to brute-force.
Why generate instead of invent?
Human-created passwords follow predictable patterns that attackers exploit. Randomly generated passwords avoid those patterns. Use a password manager to store them.
