MFA (Multi-Factor Authentication) is a security measure that often uses an SMS or third-party application as a secondary method to access a system. MFA requires the user to provide two or more pieces of evidence to prove their identity, such as something they know (e.g., password), something they have (e.g., phone), or something they are (e.g., fingerprint)2. WPA2 (Wi-Fi Protected Access 2) is a security protocol for wireless networks that does not use SMS or third-party applications. AES (Advanced Encryption Standard) is a symmetric encryption algorithm that does not use SMS or third-party applications. RADIUS (Remote Authentication Dial-In User Service) is a network protocol that provides centralized authentication and authorization for remote access clients, but does not use SMS or third-party applications.

If this file is missing or corrupted, it can cause application crashes or errors when trying to open websites in a browser. To fix this, the technician can perform a system file check, which is a utility that scans and repairs corrupted or missing system files1. To perform a system file check, the technician can follow these steps:
Open the Command Prompt as an administrator. To do this, type cmd in the search box on the taskbar, right-click on Command Prompt, and select Run as administrator.
In the Command Prompt window, type sfc /scannow and hit Enter. This will start the scanning and repairing process, which may take some time.
Wait for the process to complete. If any problems are found and fixed, you will see a message saying Windows Resource Protection found corrupt files and successfully repaired them. If no problems are found, you will see a message saying Windows Resource Protection did not find any integrity violations.
Restart your computer and check if the issue is resolved.
