如何只允许一个用户同时登录 Fire base Authentication 帐户？ [复制]

Question

:

Firebase authentication limit login by the same user (3 answers)

Closed 1 year ago .

In my angular application, user sign in through google firebase authentication account. I do not want to several users can sign in through the same account at the same times from different devices. What I expect is that when a user sign in in his device, other users will be automatically signed out from that account in their devices.

Can you tell me how can I do that?

When you use Firebase Authentication in your app there is at most one signed-in user at once. If a new user signs into the app, any previous user is automatically signed out from the app.

If this doesn't work for you, I recommend that you update your question to include the minimal code that reproduces the behavior .
