Instant Keys

Ready-made strong passwords, passphrases, Wi-Fi keys, API keys, UUIDs and encryption keys. Generated locally in your browser.

Local only

Generated in your browser. Never sent to tclient.com, stored or logged.

Values come from your browser's cryptographic random generator (the Web Crypto API, crypto.getRandomValues(), through .NET's RandomNumberGenerator), and are created only after this page is running on your device. To check: open your browser's developer tools (F12), go to the Network tab, and regenerate. No request is made. You can even disconnect from the internet after the page loads and keep generating.
