Introduction to Multi-Factor Authentication (MFA)

Q: What is Microsoft Multi-Factor Authentication (MFA)?

A: Microsoft Multi-Factor Authentication (MFA) is an additional layer of security that requires users to provide another form of identification, like password and a phone, before gaining access to SCUSD Microsoft accounts or systems. 

Q: Why is MFA important?

A: MFA adds extra protection to your account, significantly enhancing security, even if your password is compromised.

MFA Implementation and Requirements

Q: Is MFA mandatory for your SCUSD Microsoft accounts?

A: Yes, Multi-Factor Authentication (MFA), also known as 2-factor authentication, is required statewide for K-12 districts to secure Cybersecurity Insurance. SCUSD staff must enable MFA to access district resources to comply with this requirement. 

Q: How does MFA work with SCUSD Microsoft accounts?

A: When MFA is enabled, you will be prompted to provide a second form of identification after entering your password. Depending on your chosen MFA setup, this can be a code sent to your mobile device.

Q: What authentication methods are supported?

A: There are three options for second-factor authentication: The Microsoft Authenticator App is FREE. It is the incorrect App if you are prompted to pay a fee. Please confirm the Microsoft Authenticator App is from Microsoft Corporation before downloading.

1. Using the Microsoft Authenticator App that is installed on your work phone. If you have been issued a SCUSD cell phone, this is your only option for MFA authentication.
2. Install the Microsoft Authenticator App on your mobile phone. 
3. Obtain a small hardware device token to generate a random 6-digit code when needed. You can attach the token to your key ring. If you opt for the key FOB, a submission of the MFA Self Setup Wizard form is required ().

The mobile app is the preferred option for security and access. This app does NOT import work email, files, documents, or other work data onto your device. (The Authenticator App works where there is weak or no cell reception available) If you choose the preferred option to install the Microsoft Authenticator App, this process takes less than 5 minutes to register and secure your account.

Q: What is the difference between a Key Fob (Hardware Token) and Mobile App (Software Token)?

A: A key fob is a physical device that typically generates time-sensitive codes, providing a hands-on approach for access control. In contrast, a mobile app relies on using a smartphone as a virtual key to grant access. While both offer secure access, the key fob is tangible, and a mobile app leverages digital authentication methods. 

*Note: The Microsoft Authenticator App is SCUSD鈥檚 preferred option. If you opt for the key fob, please be aware that if you lose the FOB, it is stolen, or you don鈥檛 have access to it, you cannot access SCUSD resources.

Q: Is there an approved authenticator app required for Multi-Factor Authentication?

A: The Microsoft Authenticator App is the approved SCUSD mobile app for MFA. It allows you to receive push notifications for quick approval or generate time-based codes for authentication.

Setting Up MFA

Q: Do I need to be connected to the Internet or my network to get and use the verification codes?

A: The codes don鈥檛 require you to be on the Internet, so you don鈥檛 need phone service to sign in. Additionally, because the app stops running as soon as you close it, it won鈥檛 drain your battery.

Q: Is registering a device agreeing to give the company or service access to my device?

A: Registering a device gives your device access to your organization鈥檚 services and doesn鈥檛 allow your organization access to your device.

Q: I am having issues with the MFA Wizard setup. What should I do next?

A. Contact the support team directly if you need help with the MFA self-setup. You can email support@scusd.edu and provide them with details about the issues you are experiencing. The support team will contact you to provide the appropriate services and guide you through troubleshooting.

Q: What is an MFA key fob (Hardware Token)?

A: An MFA key fob, or Multi-Factor Authentication key fob, is a small electronic device that generates time-sensitive codes to add an additional layer of security to user authentication. If is commonly used as part of two-factor authentication, requiring users to provide both a password and the code from the key fob to access a system or account. 

Q: I am having issues with my MFA. How can I troubleshoot MFA issues?

A: If you encounter issues with MFA, check your internet connection, verify your authentication method, and ensure your device鈥檚 time settings are accurate. For further assistance, contact your IT support at Support@SCUSD.Edu.

Multi-Factor Authentication (MFA) and Access Sharing

Q: Can I disable MFA to share my login with substitutes, colleagues, and students when I鈥檓 away?

A: Disabling MFA is strictly prohibited for district cybersecurity and compliance reasons. Sharing login credentials poses significant security risks and violates best practices. Instead, direct users to contact Support@SCUSD.EDU for alternative solutions such as delegating access, setting up  accounts, or establishing access protocols. Only authorized users can access district resources. 

Q: How can I facilitate access for substitutes or colleagues without sharing my login credentials?

A: Only authorized users may access district resources. All permitted users will have their own unique login credentials and multi-factor authentication (MFA) setup. It is essential to maintain the security of individual accounts and adhere to cybersecurity policies to ensure responsible and secure access to district resources.

Q: I need to share my key fob with individuals who need access to documents. How can I do this?

A: Sharing Key fobs for MFA purposes is strictly prohibited, as it poses significant security risks. Instead of sharing key fobs, consider utilizing shared drives, such as Google Drive. Create a shared folder, grant appropriate access permissions, and upload the necessary documents. It鈥檚 essential to leverage secure and authorized methods, like shared drives, to facilitate document access while maintaining the integrity and security of district systems.
