Experiencing the frustrating Microsoft Account sign-in error 0x80045c3c? This guide offers effective solutions to help you regain access.
Fixing Error 0x80045c3c in Microsoft Account Sign-In
This section outlines multiple methods to tackle the error 0x80045c3c you might encounter while attempting to sign into your Microsoft Account.
Step 1: Clear Browser Cache or Switch Browsers
If you receive the sign-in error while using a browser, the issue might stem from an overload of cached files or browser-specific bugs. Start by clearing the cache.
- For most Chromium-based browsers (Edge, Chrome, and Firefox), you can use the shortcut Ctrl + Shift + Del.
- This will open the Delete Browsing Data window. Choose a Time range (up to 7 days is recommended).
- Uncheck all options except for Cached Images and Files.
- Finally, click Clear Data to remove the cached files.
Pro Tip: Opt to clear Cookies only if you are prepared to log back into various sites.
Step 2: Update TLS Version Settings
Transport Layer Security (TLS) is crucial for maintaining secure connections. With Microsoft deprecating older versions, ensure you are using TLS 1.2 or higher:
- Open the Control Panel by searching for it in the Start menu.
- Switch your View by option to Large Icons.
- Click on Internet Options, then navigate to the Advanced tab.
- Locate the settings for Use TLS 1.0, 1.1, 1.2, and 1.3 and ensure they are selected—especially 1.2 and 1.3.
- Click Apply and then OK.
Pro Tip: While removing TLS 1.0 and 1.1 is tempting, it’s safer to keep them enabled for compatibility reasons.
Step 3: Create a New Microsoft Account
Adding a new Microsoft Account creates a fresh authentication token, replacing any faulty ones. This process can resolve the sign-in errors effectively:
Log in through a local account if needed. Then, add a new Microsoft account in your settings to generate a new token for your primary account.
Step 4: Clear Application Cache
If the error arises from a specific application, clearing its cache can eliminate temporary conflicts:
- Access Windows Settings by pressing Windows + I.
- Select System > Storage > Temporary files.
- Find the Temporary Files option and ensure it is checked.
- Click the Remove Files button to clear the cache for all applications.
Pro Tip: Applications may take longer to launch initially after clearing the cache.
