How to add extra fields to Firebase auth? Age & Gender
Solution 1
When you are using Firebase authentication with user and password, the only data that you can get after authentication is that data that you get from FirebaseUser object. As you probably see, there also a couple of methods that can help you get the data easier, like: getEmail()
, getDisplayName()
, getPhotoUrl()
and so on.
Unfortunately, you cannot add additional data like age
and gender
to the FirebaseUser
object. If you want to add additional data, you need to create a model class for your user and then store it in your Firebase database.
You model class should look like this:
public class User {
String name, gender, emailAddress;
int age;
public User(String name, String gender, String emailAddress, int age) {
this.name = name;
this.gender = gender;
this.emailAddress = emailAddress;
this.age = age;
}
public String getName() {return name;}
public void setName(String name) {this.name = name;}
public String getGender() {return gender;}
public void setGender(String gender) {this.gender = gender;}
public String getEmailAddress() {return emailAddress;}
public void setEmailAddress(String emailAddress) {this.emailAddress = emailAddress;}
public int getAge() {return age;}
public void setAge(int age) {this.age = age;}
}

In general, after sign up, you can create a node tree for user like picture.
Then, you can get the info with user key that can get by calling FirebaseUser.
I hope it helps. If you have any questions, let me know.

Sorry about the delay, but I was looking for how to store considerably larger custom data - which isn't possible, however here's how I do it.
Store small amounts of extra data inside the displayName (Javascript).
result.user.updateProfile({
displayName: gender + '|' + sex + '|' + username
})
.then(function () {
console.log(`Profile updated.`);
To retrieve the data, simply split up the displayName (Node.js):
return admin.auth().getUser(uid)
})
.then(userRecord => {
displayName = userRecord.getDisplayName();
parts = String(user.displayName).split('|');
gender = parts[0];
sex = parts[1];
username = parts[2];

So far I'm really impressed with
Firebase
. But I would like to know how would I go about customizing my user email authentication. I would like to add the following fields: Age and Gender for users to fill out when registering.here's my SignUpActivity.java.
public class SignUpActivity extends AppCompatActivity { private EditText inputEmail, inputPassword, signupInputUsername, signupInputAge; private Button btnLinkLogin, btnSignUp, btnResetPassword; private ProgressBar progressBar; private FirebaseAuth auth; private Spinner sexSpinner; String defaultTextForSpinner = "Sex"; String[] arrayForSpinner = {"Male", "Female"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_signup); //Get Firebase auth instance auth = FirebaseAuth.getInstance(); inputEmail = (EditText) findViewById(R.id.signup_input_email); signupInputUsername = (EditText) findViewById(R.id.signup_input_username); inputPassword = (EditText) findViewById(R.id.signup_input_password); signupInputAge = (EditText) findViewById(R.id.signup_input_birthday); sexSpinner = (Spinner)findViewById(R.id.spinner); sexSpinner.setAdapter(new CustomSpinnerAdapter(this, R.layout.spinner_row, arrayForSpinner, defaultTextForSpinner)); btnSignUp = (Button) findViewById(R.id.btnSignUp2); btnLinkLogin = (Button) findViewById(R.id.btnorlogin); progressBar = (ProgressBar) findViewById(R.id.progressBar); EditText edittext = (EditText) findViewById(R.id.signup_input_birthday); edittext.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub //To show current date in the datepicker Calendar mcurrentDate = Calendar.getInstance(); int mYear = mcurrentDate.get(Calendar.YEAR); int mMonth = mcurrentDate.get(Calendar.MONTH); int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH); DatePickerDialog mDatePicker=new DatePickerDialog(SignUpActivity.this, new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) { // TODO Auto-generated method stub /* Your code to get date and time */ } },mYear, mMonth, mDay); mDatePicker.setTitle("Select birthday"); mDatePicker.show(); } }); btnSignUp.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String email = inputEmail.getText().toString().trim(); String password = inputPassword.getText().toString().trim(); if (TextUtils.isEmpty(email)) { Toast.makeText(getApplicationContext(), "Enter email address.", Toast.LENGTH_SHORT).show(); return; } if (TextUtils.isEmpty(password)) { Toast.makeText(getApplicationContext(), "Enter password.", Toast.LENGTH_SHORT).show(); return; } if (password.length() < 6) { Toast.makeText(getApplicationContext(), "Password too short, enter minimum 6 characters.", Toast.LENGTH_SHORT).show(); return; } progressBar.setVisibility(View.VISIBLE); //create user auth.createUserWithEmailAndPassword(email, password) .addOnCompleteListener(SignUpActivity.this, new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { Toast.makeText(SignUpActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show(); progressBar.setVisibility(View.GONE); // If sign in fails, display a message to the user. If sign in succeeds // the auth state listener will be notified and logic to handle the // signed in user can be handled in the listener. if (!task.isSuccessful()) { Toast.makeText(SignUpActivity.this, "Authentication failed." + task.getException(), Toast.LENGTH_SHORT).show(); } else { startActivity(new Intent(SignUpActivity.this, MainActivity.class)); finish(); } } }); } }); } @Override protected void onResume() { super.onResume(); progressBar.setVisibility(View.GONE); } public class CustomSpinnerAdapter extends ArrayAdapter<String> { Context context; String[] objects; String firstElement; boolean isFirstTime; public CustomSpinnerAdapter(Context context, int textViewResourceId, String[] objects, String defaultText) { super(context, textViewResourceId, objects); this.context = context; this.objects = objects; this.isFirstTime = true; setDefaultText(defaultText); } @Override public View getDropDownView(int position, View convertView, ViewGroup parent) { if(isFirstTime) { objects[0] = firstElement; isFirstTime = false; } return getCustomView(position, convertView, parent); } @Override public View getView(int position, View convertView, ViewGroup parent) { notifyDataSetChanged(); return getCustomView(position, convertView, parent); } public void setDefaultText(String defaultText) { this.firstElement = objects[0]; objects[0] = defaultText; } public View getCustomView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = inflater.inflate(R.layout.spinner_row, parent, false); TextView label = (TextView) row.findViewById(R.id.spinner_text); label.setText(objects[position]); return row; } }

darksoulsong over 4 yearsThis is a nice workaround, thank you. Do you happen to know how much info I can put into this field? How many characters? I can't find that info anywhere.

iStuart about 4 yearsFurther to my original reply, I discovered the 'correct' way to do this using "Firebase Auth Custom Claims". You can read about that here: firebase.google.com/docs/auth/admin/custom-claims and there is a fantastic NetNinja video here: youtube.com/…
