I believe there is a way for changing your password in Firebase but is there a way where the user forgets the password and can be assigned a new one or re-authenticated using email or SMS OTP. I checked out on the net but couldn't seem to find one.
If there is a way how can it be implemented, what all function calls need to be made. Could you direct me with an example.
It sounds like you're looking to send a password reset email. See this example from the Firebase documentation:
FirebaseAuth.getInstance().sendPasswordResetEmail("[email protected]")
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
}
}
});
Reset Android FireBase Password
Java File
public class ResetPasswordActivity extends AppCompatActivity {
private EditText inputEmail;
private Button btnReset, btnBack;
private FirebaseAuth auth;
private ProgressBar progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reset_password);
inputEmail = (EditText) findViewById(R.id.email);
btnReset = (Button) findViewById(R.id.btn_reset_password);
btnBack = (Button) findViewById(R.id.btn_back);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
auth = FirebaseAuth.getInstance();
btnBack.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
btnReset.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String email = inputEmail.getText().toString().trim();
if (TextUtils.isEmpty(email)) {
Toast.makeText(getApplication(), "Enter your registered email id", Toast.LENGTH_SHORT).show();
return;
}
progressBar.setVisibility(View.VISIBLE);
auth.sendPasswordResetEmail(email)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Toast.makeText(ResetPasswordActivity.this, "We have sent you instructions to reset your password!", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(ResetPasswordActivity.this, "Failed to send reset email!", Toast.LENGTH_SHORT).show();
}
progressBar.setVisibility(View.GONE);
}
});
}
});
}
}

Copied and pasted of documentation:
FirebaseAuth auth = FirebaseAuth.getInstance();
String emailAddress = "[email protected]";
auth.sendPasswordResetEmail(emailAddress)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
}
}
});
if Unity try this than
string emailaddress = resest_email.text;
FirebaseAuth.DefaultInstance.SendPasswordResetEmailAsync(emailaddress).ContinueWith((task =>
{
if (task.IsCompleted)
{
Debug.Log("Email sent.");
}
if (task.IsFaulted)
{
Firebase.FirebaseException e =
task.Exception.Flatten().InnerExceptions[0] as Firebase.FirebaseException;
GetErrorMessage((AuthError)e.ErrorCode);
return;
}
}));
}
void GetErrorMessage(AuthError errorcode)
{
string msg = "";
msg = errorcode.ToString();
print(msg);
}
Below is the simple method to send the reset password link on user email address with progress dialog (sometime firebase took time to complete reset password request because of slow internet connection on client side, so progress dialog will be helpful)
public void resetUserPassword(String email){
FirebaseAuth mAuth = FirebaseAuth.getInstance();
final ProgressDialog progressDialog = new ProgressDialog(ForgotPasswordActivity.this);
progressDialog.setMessage("verifying..");
progressDialog.show();
mAuth.sendPasswordResetEmail(email)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if(task.isSuccessful()){
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Reset password instructions has sent to your email",
Toast.LENGTH_SHORT).show();
}else{
progressDialog.dismiss();
Toast.makeText(getApplicationContext(),
"Email don't exist", Toast.LENGTH_SHORT).show();
}
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();
}
});
}
Try this method
private void resetpasswoord() {
FirebaseAuth auth = FirebaseAuth.getInstance();
String emailaddress = resest_email.getText().toString();
auth.sendPasswordResetEmail(emailaddress)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
Toast.makeText(getApplicationContext(), "Check Your Email", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(ForgotPasswordActivity.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
}
