1 toolsAbout Our Security & Privacy Tools
Good security habits depend on good tooling. These utilities are built to produce trustworthy results using the browser's own cryptographic primitives rather than weak, predictable output. When you generate a password or a random value here, it draws on a cryptographically secure source, so the result is genuinely suitable for real use.
Just as important, nothing you generate is transmitted or logged. The output exists only in your browser session, which is exactly the property you want from anything touching passwords, keys, or other sensitive values. A tool that quietly sent a generated password to a server would defeat its own purpose; these do not.
The collection covers the essentials: strong random password generation, a password strength and entropy analyzer that estimates resistance to brute-force attacks, RFC 4122 v4 UUID generation, and a cryptographically secure random number generator. Each is free and runs entirely on your device.
Frequently Asked Questions about Security & Privacy Tools
How are the random passwords generated?
ToolPilot uses window.crypto.getRandomValues(), the browser cryptographically secure pseudorandom number generator (CSPRNG), ensuring maximum unpredictability and entropy.
Are generated passwords ever sent to a server?
No. Passwords and other values are generated entirely in your browser and are never transmitted or stored anywhere.
What makes a password strong?
Length is the biggest factor: a long passphrase generally has far more entropy — and is much harder to crack — than a short password padded with symbols. The strength checker estimates this for any password you test.
