Sign in to your account

DiffGuardian signs you in through your normal web browser rather than inside the app window. This is what lets single sign-on providers such as Google work — they refuse to run inside an embedded app webview.

#The sign-in flow

1. In DiffGuardian, choose Sign in. The app opens your default browser at the DiffGuardian sign-in page.
2. Sign in — or create an account — with email or a connected identity provider.
3. Once you are authenticated, the browser hands you straight back to the app through a diffguardian:// link. Your operating system may ask for permission to open DiffGuardian; allow it.
4. The browser tab shows "Returning to DiffGuardian…" and can be closed.

Behind the scenes the website mints a single-use sign-in token that expires after five minutes and passes it to the app in that link. The app redeems it once to establish its own session. The token is never reusable and never valid anywhere else.

If the app does not come to the front automatically, the handoff page shows a click here to continue link that opens it manually.

#Accepting the legal documents

New accounts are asked to accept the Terms of Service, Privacy Policy, and AI Disclaimer during onboarding. DiffGuardian records which version of each document you accepted, along with the time. If a document is later revised, you are asked to accept the new version the next time you sign in.

You can read the current documents any time:

• Security and data handling
• Terms of Service, Privacy Policy, and AI Disclaimer — from the app's Legal screen

#Staying signed in

The app keeps its session and refreshes your plan in the background, so you normally sign in once per machine. Signing out clears the session on that machine only.
