Password Generator
Generate secure, random passwords instantly.
What is a Password Generator?
A password generator is a tool that creates random, unpredictable passwords using a cryptographically random algorithm. Unlike passwords invented by humans, generated passwords have no patterns or dictionary words that attackers can exploit, making them dramatically more resistant to brute-force and dictionary attacks.
How to Use the Password Generator
- Drag the Password Length slider to set how many characters you want — 16 or more is recommended for most accounts.
- Check the character sets you want to include: Uppercase, Lowercase, Numbers, and Symbols.
- The password field updates automatically. Click Generate New Password to create another one.
- Click the Copy icon to copy the password to your clipboard.
- Paste it directly into your password manager for storage.
- Never store passwords in plaintext — always use a dedicated password manager.
Common Use Cases
- New account registration: Generate a strong unique password for every new website or service.
- Password rotation: Replace weak or reused passwords with strong random ones during a security audit.
- API keys and secrets: Create random strings for application secrets, tokens, and symmetric encryption keys.
- Database passwords: Generate strong passwords for database users and service accounts.
- Wi-Fi passwords: Set a strong passphrase for a home or office network.
- Temporary credentials: Produce one-time passwords to share with contractors or onboarding users.
Why Use an Online Password Generator?
Humans are terrible at generating randomness. We unconsciously pick words we know, repeat patterns, or use predictable substitutions like @ for a. A browser-based generator uses the crypto API, which is backed by your operating system's cryptographically secure random number generator. This tool runs entirely in your browser — no password is ever transmitted to a server — so it is safe to generate credentials for sensitive accounts right here.
Frequently Asked Questions
How long should my password be?
Security experts recommend at least 16 characters for most online accounts, and 20 or more for high-value accounts like email, banking, and password managers. Longer passwords increase the search space exponentially, making brute-force attacks computationally infeasible even with modern hardware.
Is it safe to generate passwords in a browser?
Yes — this tool generates passwords entirely client-side using the Web Crypto API. Nothing is sent to any server. For maximum safety, close the browser tab after copying your password and never generate passwords on a public or shared computer.
Should I use symbols in my passwords?
Yes, when the service allows it. Including symbols like !@#$%^&* significantly expands the character set, increasing entropy and making brute-force attacks far slower. Some services restrict which symbols are allowed, so you can uncheck the symbols option if a site rejects your password.
