Experiencing an endless authentication loop can bring your productivity to a sudden halt. When your system continuously demands your credentials without actually logging you in, Understanding the process of fixing Repeated Sign-In Prompts for an OnMicrosoft Account becomes an urgent priority. This looping behavior typically occurs when Windows and your desktop applications fail to synchronize your cloud-based Entra ID identity with the local cryptographic tokens stored on your device. Whether the root cause lies in corrupted local cache files, conflicting identity registries, or hardware security state mismatches, this troubleshooting guide provides the exact diagnostic steps required to break the loop and restore your access.
Clearing Cached Credentials to Resolve the Loop

The most common cause of an authentication loop is a corrupted saved password. When attempting to understand fixing Repeated Sign-In Prompts for an OnMicrosoft Account, your primary diagnostic check should involve purging the outdated tokens stored by the Windows operating system.
- Step 1: Close all running applications, particularly Word, Excel, PowerPoint, and Outlook.
- Step 2: Click the Windows Start button, type Credential Manager in the search bar, and press Enter to launch the control panel applet.
- Step 3: Click on the Windows Credentials tab at the top of the window.
- Step 4: Scroll down to the Generic Credentials section. Look for any list items beginning with MicrosoftOffice16_Data, SSO_POP_Device, or OneDrive Cached Credential.
- Step 5: Click the drop-down arrow next to each relevant entry and select Remove. Confirm the deletion when prompted.
- Step 6: Restart your computer to ensure the local cache is entirely flushed, then launch your application to generate a clean login prompt.
Reconnecting Your Profile in Windows Settings
If clearing the credential cache does not resolve the issue, the connection between your local machine and the organizational server might be damaged. For people working on fixing Repeated Sign-In Prompts for an OnMicrosoft Account, refreshing this device-level connection is the next sequential action.
- Step 1: Press the Windows key + I to open the Settings application.
- Step 2: Click on Accounts in the left navigation sidebar, then select Access work or school from the main pane.
- Step 3: Locate your specific account ending in .onmicrosoft.com from the connected devices list.
- Step 4: Click on the account to expand the options and press the Disconnect button. Read the warning prompt and confirm the removal.
- Step 5: Restart your machine to clear any lingering device management policies.
- Step 6: Return to the Access work or school menu, click the Connect button, and enter your email and password to establish a fresh connection to the server.
Resetting Office Activation States and Registry Keys
When local files and device connections are functioning correctly but the symptom persists, a corrupted identity registry key can force the software to continually ask for verification. To execute a complete fix on fixing Repeated Sign-In Prompts for an OnMicrosoft Account, you must clear these cached registry identities safely.
- Step 1: Press the Windows key + R to open the Run dialog box. Type regedit and press Enter to open the Registry Editor.
- Step 2: Navigate precisely to the following path using the left sidebar: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity.
- Step 3: Right-click the Identity folder and select Export. Save this backup file to your Desktop in case you need to restore the previous state.
- Step 4: After backing up, right-click the Identities sub-folder located directly inside the main Identity folder, and select Delete.
- Step 5: Close the Registry Editor and reboot your system. The software will automatically rebuild a clean version of this folder the next time you sign in.
Alternative Mechanism: Clearing the Trusted Platform Module (TPM)
If you have cleared both the credentials and the registry but still face the loop, your hardware's security chip may hold a corrupted cryptographic key. This is a genuinely different mechanism for handling fixing Repeated Sign-In Prompts for an OnMicrosoft Account, as it targets the motherboard's hardware layer rather than the software layer.
- Step 1: Click the Windows Start button, type Windows Security, and open the application.
- Step 2: Click on Device security, then click the Security processor details link.
- Step 3: Click on Security processor troubleshooting.
- Step 4: Click the Clear TPM button. Note: If your system uses BitLocker drive encryption, ensure you have your BitLocker recovery key saved to an external USB drive before performing this step, as clearing the TPM will trigger a recovery prompt on the next boot.
- Step 5: Restart your computer and set up your PIN and account again.
Working with WPS Office as a Stable Alternative

Sometimes, the authentication loop is caused by server-side enterprise licensing issues or strict administration policies that you cannot immediately bypass. WPS Office cannot change Microsoft-side security settings or directly alter your Entra ID configurations. However, if you are stuck troubleshooting fixing Repeated Sign-In Prompts for an OnMicrosoft Account and urgently need to edit your documents, transitioning to WPS Office bypasses the identity gateway entirely to achieve your underlying document goals.
WPS Office operates independently of enterprise cloud enforcement while maintaining high compatibility with your existing .docx, .xlsx, and .pptx file formats.
- Step 1: Locate your locally saved documents on your hard drive.
- Step 2: Right-click the target file, select Open with, and choose WPS Office from the application list.
- Step 3: Edit your files utilizing WPS's offline capabilities.
WPS Office provides a stable structure that does not rely on constant background authentication with a remote server. Additionally, built-in features like its AI-powered PDF-to-Word conversion tools and smart templates operate natively within the suite, ensuring your workflow remains uninterrupted even when enterprise cloud syncs fail.
FAQ
Why does my account keep asking for a password even after I enter it correctly?
This happens because the secure token passed from the authentication server conflicts with a corrupted token stored locally in your Windows Credential Manager or hardware TPM. You can master fixing Repeated Sign-In Prompts for an OnMicrosoft Account by manually clearing these corrupted caches, which forces the operating system to negotiate and store a brand-new, uncorrupted security token.
Will disconnecting my work or school profile delete my local files?
No, disconnecting your profile from the Windows Settings menu only removes the authentication link and local device management policies. Your locally saved word processing documents, spreadsheets, and personal files remain entirely untouched. Implementing fixing Repeated Sign-In Prompts for an OnMicrosoft Account through this method is completely safe for your hard drive data, though you will temporarily lose access to live cloud-synced folders until you reconnect.
Does the Registry reset method apply to both Windows 10 and Windows 11?
Yes, navigating to the 16.0 Identity registry key functions identically across both operating systems. The core architecture of how desktop applications cache user identities has not changed between these versions. Therefore, the registry steps for fixing Repeated Sign-In Prompts for an OnMicrosoft Account are universally applicable to any modern Windows environment running current versions of the software suite.
Can WPS Office sync directly to my server if the native app fails?
WPS Office handles local files consistent, but if your enterprise server is actively rejecting connections due to a security policy or looping error, third-party applications will also face synchronization barriers. To maintain productivity while working on fixing Repeated Sign-In Prompts for an OnMicrosoft Account, your best approach is to download the files locally, edit them in WPS Office, and manually upload the finished versions via your web browser, which successfully bypasses local desktop application authentication loops.
