Question

我相信有一种方法可以在Firebase中更改您的密码，但有一种方法可以让用户忘记密码，并可以分配新密码或使用电子邮件或短信OTP重新验证。我在网上查了一下但似乎找不到一个。

如果有一种方法可以实现，那么需要进行所有函数调用。你能用一个例子指导我吗？

Answer 1

听起来您正在寻找发送密码重置电子邮件。见this example from the Firebase documentation：

FirebaseAuth.getInstance().sendPasswordResetEmail("user@example.com")
    .addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                Log.d(TAG, "Email sent.");
            }
        }
    });

重置Android FireBase密码

Java文件

    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);
                            }
                        });
            }
        });
    }

}

简而言之，Firebase有一种方法可以使用名为changePassword的方法，请点击链接查看如何实现它。

Answer 4

复制并粘贴documentation：

FirebaseAuth auth = FirebaseAuth.getInstance();
String emailAddress = "user@example.com";

auth.sendPasswordResetEmail(emailAddress)
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "Email sent.");
                }
            }
        });

Answer 5

以下是使用进度对话框在用户电子邮件地址上发送重置密码链接的简单方法（有时firebase需要时间来完成重置密码请求，因为客户端连接速度较慢，因此进度对话将有所帮助）

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();
            }
        });
    }

Answer 6

尝试此方法

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();
                    }
                }
            });
}

Answer 7

如果Unity试试这个比

    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);
}

如果 Kotlin 是您选择的语言，您可以使用：

Failed to connect to repository : Error performing command: 
C:\Users\user\AppData\Local\Programs\Git\bin\ ls-remote -h 
git@gitlab:user/project.git HEAD

Answer 9

如果您是在Flutter中进行操作，请使用以下命令：

 @override
Future<void> resetPassword(String email) async {
    await _firebaseAuth.sendPasswordResetEmail(email: email);
}
