I am following newest version of Firebase Google Web SDK. Everything from login to sign up and sign out works just fine. I want to let users delete their own accounts and followed the API reference for firebase.User class. Also I read their docs about managing users.

This is the code I use:

function deleteAccount () {
  console.log('delete account!!')
  const auth = firebase.auth()
  console.log({auth})

  auth.delete().then(function () {
    console.log('delete successful?')
    const user = firebase.auth().currentUser
    console.log({user})
    store.dispatch(forgetUser())
    routerReset('GetStarted')
  }).catch(function (error) {
    console.log({error})
    // An error happened.
  })
}

The function delete appears to work from firebase.Auth object and resolves the promise. If doing the same with signOut the log presents an undefined object, however here:

console.log({user}) // { user: Firebase.User object }

No error is emitted.

NOTE: this is a react-native app.

You seem to be missing a reference to currentUser.

From the Firebase documentation on deleting a user:

You can delete a user account with the delete method. For example:

var user = firebase.auth().currentUser;

user.delete().then(function() {
  // User deleted.
}, function(error) {
  // An error happened.
});

Important: To delete a user, the user must have signed in recently. See Re-authenticate a user.

As said, your code doesn't reference currentUser. I'm not sure what calling delete on the auth object itself does.

Update: I just ran this to validate the behavior:

firebase.auth().currentUser.delete().then(function () {
  console.log('delete successful?')
  console.log(app.auth().currentUser)
}).catch(function (error) {
  console.error({error})
})

At first I got a 400, with the body of the response saying that it'd been too long since I signed in. After re-authenticating and trying again, I got:

delete successful?

null

To delete a user, the user must have signed in recently.
