Password Generator
Generate strong, secure, random passwords instantly with our free online Password Generator. Create passwords with customizable length and character types including uppercase letters, lowercase letters, numbers, and special symbols. Perfect for creating secure accounts, API keys, WiFi passwords, and any situation requiring strong authentication credentials. All password generation happens locally in your browser — your passwords are never transmitted over the internet or stored on any server, ensuring maximum security and privacy.
What Is
A Password Generator is a tool that creates random, cryptographically secure passwords using a combination of character sets. Strong passwords are essential for protecting online accounts, sensitive data, and digital identities from unauthorized access, brute-force attacks, and credential stuffing. This generator allows you to customize password length (typically 8-128 characters), include or exclude uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special characters (!@#$%^&* etc.). You can also exclude ambiguous characters (like l, 1, I, O, 0) to avoid confusion when reading passwords. The tool uses cryptographically secure random number generation (Web Crypto API) to ensure each password is truly unpredictable. Unlike many online password generators, this tool processes everything locally in your browser — no password is ever sent to a server, logged, or stored anywhere. This makes it ideal for generating passwords for high-security applications, financial accounts, and any situation where privacy is paramount.
How to Use
- Open the Password Generator tool in your browser — no registration or installation required.
- Set your desired password length using the slider or input field (recommended: 12-16 characters for most uses).
- Select which character types to include: uppercase letters, lowercase letters, numbers, and special symbols.
- Optionally enable the 'exclude ambiguous characters' option to avoid confusing characters like l/1/I or O/0.
- Click the 'Generate' button to create a new random password instantly using cryptographically secure randomness.
- Copy the generated password to your clipboard with the copy button and use it for your account or application.
Examples
Input: Length: 16, Options: upper+lower+digits+symbols
Process: Charset: 26+26+10+32=94 → Random select 16 chars → Entropy: log2(94^16)
Result: kR7$mP2!xQ9&nL5@ (104 bits entropy)
Input: Length: 32, Options: lower+digits only
Process: Charset: 26+10=36 → Random select 32 chars → Entropy: log2(36^32)
Result: a7k2m9p4r1x6n8q3w5e0t2y7u4i9o1p (165 bits)

Frequently Asked Questions
How secure are the generated passwords?
The passwords are generated using the Web Crypto API's cryptographically secure random number generator (CSPRNG), which provides true randomness suitable for security-sensitive applications. Each character is selected independently from the chosen character set, ensuring uniform distribution and maximum entropy. This is significantly more secure than pseudo-random generators used by many online tools.
What password length do you recommend?
For most online accounts, we recommend a minimum of 12-16 characters with a mix of uppercase, lowercase, numbers, and symbols. For high-security applications like banking, email, or password managers, consider using 20+ characters. Longer passwords exponentially increase the time required for brute-force attacks, making them significantly more secure.
Is it safe to use an online password generator?
This specific tool is safe because all password generation happens locally within your browser using JavaScript. No password is ever transmitted to a server, stored in a database, or logged anywhere. The generation uses the Web Crypto API for cryptographically secure randomness. However, always ensure you're using the official site and verify the URL to avoid phishing attempts.
Can I generate passwords for specific requirements?
Yes, the generator allows you to customize which character types are included, so you can meet specific password policy requirements. For example, if a site requires at least one uppercase, one number, and one special character, simply enable those options. You can also exclude ambiguous characters for sites where you might need to read the password aloud or type it manually.
Should I use a password manager instead?
We strongly recommend using a password manager (like Bitwarden, 1Password, or KeePass) for storing and managing your passwords. This generator is ideal for creating strong passwords that you then store in your password manager. Never reuse passwords across sites, and use a unique strong password for each account. A password manager makes this practical by remembering all your passwords securely.
