Android上的Windows APP通过内网连接Windows桌面时，要求输入用户名和密码，但是我已经再三确定账号密码是正确却仍然报错

Question

尝试使用Android手机上的Windows APP通过内网远程桌面我的Windows电脑，已经成功到证书信任那一步了，但是选择信任后，用户名和密码永远是错的，我尝试了Admin Administrator 以及我的微软账户邮箱配合我的微软账户密码或电脑pin码甚至留空却仍然无法登陆，目前可以确定的是我的被控电脑是使用Windows hello人脸+pin码的方式进行登录验证的，请问这个页面我应该输入什么账号密码

Welcome to the Microsoft Q&A Platform!

First, let me help you to clarify an important point about your setup.

Windows Hello Face and PIN cannot be used for Remote Desktop (RDP) logins. These methods work only for local sign-in. When connecting through the Windows app on Android, you must sign in using a standard username + password, not the PIN, not face recognition and not a blank password.

Secondly, below are the steps that I would like to recommend based on the behavior you described.

1. Use the correct username format + Microsoft account password

Since your Windows PC uses a Microsoft account with Windows Hello, RDP requires your Microsoft account password (the same one used on Outlook.com / Office.com), not the PC PIN.

Try these username formats in the Windows App on Android (top → bottom):

• Option 1 (most reliable for Microsoft accounts)

Username: MicrosoftAccount******@outlook.com

Password: <your Microsoft account password>

• Option 2

Username: ******@outlook.com

Password: <same Microsoft account password>

• Option 3 (only if you have a local account on the PC)

Username: PCNAME\localusername

Password: <local account password> (Blank passwords will not work over RDP)

2. Ensure a real password exists and Windows Hello isn’t blocking RDP

• On the Windows PC
• Open Settings → Accounts → Sign-in options
• Under Additional settings, disable: “Require Windows Hello sign-in for Microsoft accounts” (If this is ON, RDP password login may be blocked)
• Make sure your Microsoft account has a password set.

If you changed it online recently, sign out and sign in using the password (not PIN) to sync it.

3. Check Remote Desktop permissions

Make sure your account is allowed to sign in remotely

• Add user to Remote Desktop Users
• Press Win + R → compmgmt.msc
• Local Users and Groups → Groups → Remote Desktop Users
• Add your Microsoft account or local account
• Local Security Policy

Open secpol.msc → Local Policies → User Rights Assignment:

• Allow log on through Remote Desktop Services → must include your user (Administrators/Remote Desktop Users)
• Deny log on through Remote Desktop Services → make sure your user/group is not listed

(Deny overrides Allow)

4. Confirm Remote Desktop service and firewall

• services.msc → Remote Desktop Services (TermService) → Running
• Firewall → Allowed Apps → Remote Desktop enabled for your network profile
• If possible, test RDP from another Windows PC on the same LAN
• If it works → the issue is the username format on Android
• If it fails → the issue is server-side (permissions, password)

Thank you for your asking your question.
