How to change password using Firebase in Flutter

Question

I want to change current user password using Firebase in Flutter. Can any one help me on how to implement change password method?

Answer 1

I know this is a late post, but now it's possible to change the password of the logged-in user. Make sure to notify the user to log in again since this is a sensitive operation.

void _changePassword(String password) async{
   //Create an instance of the current user. 
    FirebaseUser user = await FirebaseAuth.instance.currentUser();
   
    //Pass in the password to updatePassword.
    user.updatePassword(password).then((_){
      print("Successfully changed password");
    }).catchError((error){
      print("Password can't be changed" + error.toString());
      //This might happen, when the wrong password is in, the user isn't found, or if the user hasn't logged in recently.
    });
  }

If you are here for the solution in 2021 and getting reauthenticate error ->

void _changePassword(String currentPassword, String newPassword) async {
final user = await FirebaseAuth.instance.currentUser;
final cred = EmailAuthProvider.credential(
    email: user.email, password: currentPassword);

user.reauthenticateWithCredential(cred).then((value) {
  user.updatePassword(newPassword).then((_) {
    //Success, do something
  }).catchError((error) {
    //Error, show something
  });
}).catchError((err) {
 
});}

This should work according to the latest version of firebase:

final FirebaseAuth firebaseAuth = FirebaseAuth.instance;  
User currentUser = firebaseAuth.currentUser; 
currentUser.updatePassword("newpassword").then((){
  // Password has been updated.
}).catchError((err){
  // An error has occured.
})

Answer 4

This is currently not supported.

When this pull request is merged https://github.com/flutter/plugins/pull/678 the Flutter firebase_auth package will support that.
