Password Generator
Generate strong, secure random passwords using cryptographic randomness. Customize length, character types, and generate in bulk.
How to Use the Password Generator
- Set length -- Use the slider to pick a password length between 8 and 128 characters. Longer passwords are more secure.
- Choose character types -- Toggle uppercase, lowercase, numbers, and symbols. Enable at least one type.
- Exclude ambiguous characters -- Check this option to remove visually similar characters (0, O, I, l, 1) for easier reading.
- Generate -- Click the button or change any option to auto-generate. Use the batch dropdown to create multiple passwords at once.
- Copy -- Click Copy to send the password(s) to your clipboard instantly.
About Strong Passwords
A strong password is one of the most important defences for your online accounts. This generator uses the Web Crypto API (crypto.getRandomValues()) to produce cryptographically secure randomness, ensuring that every password is truly unpredictable. Unlike pseudo-random generators, cryptographic randomness is suitable for security-sensitive applications.
Security experts recommend passwords of at least 12 characters mixing all four character types. Avoid reusing passwords across sites, and consider using a password manager to store them safely. This tool runs entirely in your browser -- no passwords are transmitted over the network or stored on any server.
Frequently Asked Questions
This generator uses the Web Crypto API (crypto.getRandomValues()) to produce cryptographically secure random values. These values are mapped to your selected character set to build each password. Everything runs in your browser -- nothing is sent to a server.
A strong password is at least 12 characters long and uses a mix of uppercase letters, lowercase letters, numbers, and special symbols. It should not contain dictionary words, personal information, or common patterns like "123456" or "qwerty".
Yes. All passwords are generated entirely in your browser using cryptographic randomness. No data is sent to any server, no passwords are logged, and nothing is stored. You can even use this tool offline.
Yes. Use the batch dropdown to select 5, 10, or 20 passwords. They will all be generated with the same settings and displayed in a text area for easy copying.
