How to Fix Microsoft Edge and Office Apps Repeatedly Requesting Sign-In
Question details
Users are experiencing persistent sign-in requests and synchronization failures across Microsoft Edge and Office applications.
- Product
- Microsoft Office, Microsoft Edge
- Device & OS
- Windows
- Scenario
- Attempting to use Microsoft Office applications or the Edge browser without being constantly interrupted by authentication prompts.
- Observed behavior
- Microsoft applications display warning icons, fail to synchronize account data, and repeatedly prompt the user to sign in despite having an active subscription.
Ensure you have your Microsoft account credentials ready and confirm that your Microsoft 365 Personal subscription is active via your account dashboard.
Install System BIOS and Firmware Updates
Installing the latest BIOS update from your computer manufacturer can resolve underlying hardware authentication glitches causing repeated prompts.
In some instances, device firmware inconsistencies interfere with Windows authentication tokens, causing apps like Edge and Office to repeatedly ask for credentials. Updating the BIOS, particularly on devices like Lenovo laptops, often resolves these persistent sign-in loops.
Open a web browser and navigate to the official support website of your computer manufacturer (for example, Lenovo, Dell, or HP).
Enter your laptop's serial number or model name (e.g., Lenovo Yoga Slim 7 Pro) in the search bar to access the specific drivers for your machine.
Navigate to the 'Drivers & Software' section, find the latest BIOS/UEFI update package, and download it to your computer.
Run the downloaded executable file and carefully follow the on-screen instructions. Make sure your laptop is plugged into a power source, and allow the system to restart to apply the firmware update.
Verify Account License and Install Software Updates
Check your Microsoft 365 license validity and ensure Windows and Office applications are fully up to date.
Try WPS Office for a Stable, Login-Free Document Experience
If persistent Microsoft Office account syncing issues continue to disrupt your workflow, consider switching to WPS Office. It provides a lightweight, highly compatible, and seamless document editing experience without the constant need for cloud authentication.
- 1. Download WPS Office: Visit the official WPS Office website and click the free download button for your operating system.
- 2. Install the software: Run the downloaded installer and follow the quick setup wizard to install the suite on your computer.
- 3. Open your files instantly: Right-click any existing Microsoft Office document, select 'Open with WPS Office', and start editing seamlessly without needing to sign in.
Frequently Asked Questions
Why does Microsoft Word keep asking me to sign in?
This usually indicates a syncing error with your Microsoft account, an expired license, outdated software, or hardware authentication conflicts such as an outdated system BIOS.
Can a BIOS update really fix Office sign-in problems?
Yes. On certain devices, specific firmware versions may interfere with the secure authentication tokens used by Windows and Microsoft apps. Updating the BIOS ensures the hardware communicates properly with Windows security features.
How do I check if my Microsoft 365 subscription is active?
Go to account.microsoft.com, sign in with your credentials, and navigate to the 'Services & subscriptions' tab. Here you can verify the status and expiration date of your current plan.
What should I do if updating the BIOS doesn't stop the sign-in prompts?
If the problem persists, try signing out of all Microsoft accounts in your Windows Settings under 'Accounts' > 'Email & accounts', clearing your credential manager, and signing back in.
