Password Generator
Generate cryptographically strong passwords using your browser's native CSPRNG. Control length, character classes, and entropy score. Nothing is sent to any server.
How to Use Password Generator
Use the length slider or input field to set your required character count. For general account passwords, 16 characters is a safe starting point. For API keys, SSH secrets, or database credentials, aim for 32 to 64 characters. The entropy score updates in real time as you adjust the slider.
Toggle uppercase letters, lowercase letters, digits, and special characters on or off using the checkbox panel. If a legacy system prohibits certain symbols, remove them from the pool before generating. The tool recalculates the available character pool and entropy estimate immediately so you can see the exact security impact of any restriction.
Click Generate Password to produce a result. Each click fires a fresh call to window.crypto.getRandomValues(), which draws entropy from your operating system's kernel-level randomness pool — the same source used in TLS handshakes. Every result is statistically independent from the previous one. Regenerate as many times as needed at no cost.
Copy the generated password immediately and paste it into your password manager. Avoid storing it in a plain-text file or an unencrypted note. The value exists only in your browser's working memory for the duration of your session — nothing is transmitted to any server and nothing is retained after you close the tab.
Frequently Asked Questions
Everything you need to know about Password Generator
Is a browser-based password generator actually secure?
Yes, provided it uses window.crypto.getRandomValues() rather than Math.random(). The Web Cryptography API is a W3C standard backed by your operating system's kernel-level entropy pool, making it cryptographically indistinguishable from hardware random number generators for practical purposes. ToTheWebPro uses only this CSPRNG path and makes zero network requests during generation.
How many bits of entropy do I need for a strong password?
NIST SP 800-63B recommends at least 112 bits for high-value accounts. A randomly generated 20-character password using all four character classes produces approximately 131 bits — well above that threshold. For critical infrastructure credentials such as SSH keys or root accounts, target 160 bits or more.
Can this tool generate passwords that work with systems that have strict character rules?
Yes. Remove any specific characters from the character pool before generating. For example, if a legacy system rejects @ or backslash, remove them from the special character subset and the tool generates from the constrained pool while recalculating entropy so you can see the exact security cost of those restrictions.
What length should I pick?
Sixteen or more characters is a practical baseline for modern web services. For API keys, database credentials, and any secret stored in an environment variable, use 32 characters or more. The entropy meter shows you the exact bit strength at each length so you can make an informed decision based on your specific risk context.
Does Vercel or ToTheWebPro see my generated passwords?
No. Vercel serves the static HTML, CSS, and JavaScript files to your browser. Password generation happens entirely after that file delivery, inside your browser's JavaScript engine. Vercel's servers are never contacted during generation. There is no API endpoint, no serverless function, and no telemetry call triggered at generation time.
