Practical guide: Password Generator
Why use this tool?
Generating a strong, unique password for each account is the first rule of cybersecurity. This tool creates random passwords to your specifications: length, uppercase, numbers, special characters, custom exclusions. Use it for any online account, database, Wi-Fi network or encryption key.
Dictionary attacks and brute force are defeated by long random passwords. Avoid predictable substitutions (a→@, i→1) that attackers already know.
Privacy and limits
Generation is 100% local via the browser's native cryptographic API (crypto.getRandomValues). No generated password is transmitted or stored.
Password Generator is designed to be free, fast and available without creating an account. It suits freelancers, students, marketing teams, developers and small businesses that need to handle a task efficiently.
Best practices
- Use a different password for every service.
- A good password is at least 16 characters with uppercase, digits and symbols.
- Store passwords in a manager (Bitwarden, 1Password).

Frequently asked questions
Is the generator really secure?⌄
Yes. We use the Web Crypto API (crypto.getRandomValues), which is cryptographically secure, unlike Math.random which is predictable.
Are my passwords transmitted?⌄
No, never. Everything is generated in your browser. No data leaves your device.
What is entropy?⌄
It measures password strength in bits. The higher, the harder to guess. Aim for 60+ bits for standard use, 128+ for critical accounts.
Why exclude ambiguous characters?⌄
To avoid visual confusion between 0/O, l/1, |/I which can make manual entry painful.
How many characters are safe?⌄
Minimum 12 characters for non-critical accounts. 16-20 for important ones (banking, email). 24+ for system admin.
