Know When a Website Uses Outdated Security.

Free and open source

Does your website pass the test?

Implicit Flow Detector is a browser extension that lets you know when a website uses the deprecated OpenID Connect/OAuth 2.0 Implicit Flow.

The extension intercepts id tokens and access tokens and shows you their values. A malicious browser extension or other javascript could use an intercepted access token to make API calls on your behalf without your knowledge.
