Password Generator
Create secure and random passwords customizable to your needs.
About this tool
The password generator is an essential tool for digital security that allows creating strong, random, and hard-to-guess passwords. This tool uses a cryptographically secure random number generator to create passwords that meet modern security standards. You can customize the password length and select which character types to include: uppercase, lowercase, numbers, and special symbols. The generated passwords are completely random and are not stored or sent to any server, ensuring your information remains private. It's especially useful for creating new passwords for online accounts, regenerating compromised or old passwords, or when you need temporary passwords for testing or development. The tool processes everything locally in your browser using the native crypto.getRandomValues() API, ensuring maximum security and privacy.
Use cases
- Create secure passwords for new online accounts
- Regenerate compromised or old passwords
- Generate temporary passwords for development testing
- Create passwords for services requiring periodic renewal
Frequently asked questions
- What password length should I use?
- For 2024, a minimum of 16 characters is recommended. Passwords of 20+ characters with a mix of uppercase, lowercase, numbers, and symbols offer the best protection against brute-force attacks.
- Are the generated passwords really secure?
- Yes, this tool uses crypto.getRandomValues() from the browser, which is a cryptographically secure random number generator. The passwords are completely random and don't follow predictable patterns.
- Are the generated passwords stored?
- No, passwords are not stored or sent to any server. They are generated locally in your browser and only exist temporarily while you view them. Once you reload the page, they're lost.
- Why should I use a generator instead of creating my own password?
- Humans tend to create passwords based on memorable patterns (words, dates, names) that are vulnerable to dictionary attacks. A generator creates truly random passwords without predictable patterns.
