I am looking to fetch lastSignInTime for all users by using the UID of the users.
I am using react.js
I have attached a screenshot of it so that you will have an idea of what I am looking for.
Hope, you guys help me out with this.

There is no way to access profile information about other users than yourself from within the client-side SDKs of Firebase Authentication.
If you need such information in your app, the two main options are:
- Write the information to a cloud-based database (such as Firebase's own Realtime Database or Firestore) when they sign in, and read it from there.
- Use the Admin SDK to access this information for all users in a trusted environment, such as a server you control or Cloud Functions. From there you can then expose the information to your ReactJS application as a custom API.,
In both cases, be sure to take care of securing access to the information, by limiting the amount of data you expose and who can access it.
