Password Generator
Generate cryptographically secure random passwords with customizable length, character types, and batch generation. Uses your browser's crypto API.
Usage notes
- Uses crypto.getRandomValues() for true cryptographic randomness.
- A strong password should be at least 12 characters with mixed types.
- Generate up to 50 passwords at once for bulk needs.
- Never reuse passwords across different services.
How to Use This Tool
- 1Set the desired password length (8-128 characters).
- 2Choose which character types to include.
- 3Set the count if you need multiple passwords.
- 4Click 'Generate' and copy the result.
Frequently Asked Questions
- Are these passwords truly secure?
- Yes. They use the Web Crypto API (crypto.getRandomValues), which provides cryptographically strong random values. This is the same source of randomness used in TLS and other security protocols.
- Is my password stored or sent anywhere?
- No. Passwords are generated entirely in your browser and never transmitted. We have no way to see or store them.
- How long should my password be?
- At least 12 characters for general accounts. 16+ characters for sensitive accounts like banking, email, or password managers. Longer is always better.
- Should I include symbols?
- Yes, if the service allows them. Symbols dramatically increase the search space an attacker must cover.
