How to generate a strong password
Generate strong, random passwords in your browser with adjustable length and character sets.
A strong password is long and random. Use a generator that draws from your browser’s cryptographically secure random source and lets you set the length and character sets (uppercase, lowercase, digits, symbols). Aim for at least 16 characters with mixed types.
Input

Steps
- Open the Password tool and set the length (16+ recommended).
- Choose which character sets to include — more variety means more entropy.
- Generate and copy the password; refresh for a new one.
- Use a unique password per site and store them in a password manager.
Frequently asked questions
- What makes a password strong?
- Length and randomness — entropy. A long, randomly generated password resists brute force far better than a short one with clever substitutions. 16+ random characters across multiple character sets is a solid baseline.
- Are these passwords sent anywhere?
- No. They are generated locally in your browser using the Web Crypto API and never transmitted to any server.
