面试项目：本地环境Facebook登录处于开发模式，如何开放测试权限？

Hey there! I totally get the stress of prepping for an interview demo where your Facebook Login feature only works for you—let's get this sorted so your interviewer can test it too, no public app required.

Here's the most straightforward, official solution that avoids creating clunky test accounts:

Add Your Interviewer as a Tester in Your Facebook App #

Facebook lets you grant access to specific users (like your interviewer) in developer mode without needing to publicize the app or submit a privacy policy. Here's how to do it:

• Log into the Facebook Developer Platform and open your app dashboard.
• On the left sidebar, navigate to Roles → Testers.
• Click the Add Testers button, then enter your interviewer's Facebook email address or their Facebook user ID.
• Your interviewer will get a notification (or email) inviting them to become a tester for your app. Once they accept, they'll be able to use their own Facebook account to log into your app just like you can.

Why this works: #

In developer mode, Facebook restricts Login access to only the app's admins, developers, and testers. Adding someone as a tester is a built-in way to grant temporary access for testing purposes—no need to go through the full App Review process, set up a public domain, or draft a privacy policy (since this is internal testing, not public use).

This is way better than creating test accounts because your interviewer can use their real Facebook profile, making the demo feel more natural and authentic.
