You can simply use the predefined amplify method like below. const currentUser = await Auth.currentAuthenticatedUser();

@goatandsheep When you get resolved from Auth.signIn() with that user object, you are not actually signed in because you need to complete the new password. So at that moment Auth.currentSession and Auth.currentAuthenticatedUser won’t work because you are not signed in. You need to directly use that user object returned from Auth.signIn() to help you finish the login process.
