What Is a Password Generator?
Password Generator is a free online tool that generate strong, random passwords with customizable length and character sets. No files are uploaded — everything is processed locally on your device.
A password generator creates strong, random passwords using cryptographically secure random number generation. Strong passwords are the first line of defense against unauthorized access to your accounts. Our generator runs entirely in your browser, meaning your generated passwords are never transmitted to any server, stored in any database, or visible to anyone but you.
Privacy guarantee: Password Generator processes all files directly in your browser using WebAssembly. No data is uploaded to any server, no information is collected, and the tool works offline after loading. Unlimited usage with no signup, no watermarks, and no file size limits.

Password Strength Benchmarks
Length contributes more to practical security than symbol-heavy complexity alone. Randomly generated credentials remain the safest default for account security.
- 12-char random password: Strong baseline — Suitable for many everyday accounts
- 16+ char random password: High security — Recommended for email, finance, and admin access
- Reuse risk impact: Critical — Unique password per service reduces breach blast radius
| Scenario | Best Choice | Why |
|---|---|---|
| Primary email account | 16-20 char random + MFA | Highest-value account needs strongest controls |
| Team shared systems | Generated secrets in manager | Prevents human-generated weak patterns |
| Legacy system with strict limits | Max allowed length + full charset | Maximizes entropy within constraints |
High-Intent Use Cases
Employee onboarding
Issue strong initial secrets with policy-compliant complexity.
Breach response
Regenerate compromised credentials with immediate uniqueness.

Frequently Asked Questions
How long should my password be?
Security experts recommend at least 12-16 characters for strong passwords. Longer passwords are exponentially harder to crack. A 16-character password using mixed character types would take millions of years to brute-force with current technology.
Is it safe to generate passwords in a browser?
Yes, when the generator uses client-side JavaScript with the Web Crypto API, as ours does. The password is generated locally on your device and never transmitted. This is safer than server-side generators where passwords could be logged.
Should I use special characters in my password?
Including special characters (like !@#$%^&*) significantly increases password strength by expanding the character space an attacker must consider. However, length matters more than complexity — a long password with just letters and numbers is often stronger than a short one with special characters.
