OAuth Last Used

About

OAuth Last Used helps you remember which sign-in provider you used on each website.

If you ever wonder “Did I sign in with Google, GitHub, Apple, or Microsoft on this site?”, this extension adds a small “Last used” badge to the provider you used before.

The extension works locally in your browser. When you click an OAuth sign-in button, it stores the selected provider for that website. The next time you visit the same login page, it highlights the matching provider.

Features:

- Adds a “Last used” badge to your previous OAuth provider
- Works with common providers like Google, GitHub, Apple, Microsoft, and others
- Supports many login page patterns, including OAuth links, provider text, data attributes, and provider icons
- Handles Google’s account chooser, so you can remember which Google account you used for a site
- Private by design: data stays in Chrome local storage

No tracking, no analytics, no account, and no network requests

OAuth Last Used is lightweight and simple: it only helps you avoid guessing which login method you used before.

The code is open-source and it's quite simple. You can check it or even ask you coding agent to create your own version.
