Tips for better results
Review options before generating. Click again if you need another candidate. Prefer copying instead of screenshotting secrets.
Privacy and offline-friendly processing
Whenever possible, Coin Flip processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
