This document outlines a plan to implement multi-factor authentication (MFA) for county users accessing applications and services remotely. It includes: - Piloting MFA with internal IT teams before rolling out more broadly. - A phased county-wide deployment beginning in September 2021 with directors and senior staff, then other departments. - Support for end users including communications, guides, and in-person assistance for setup. - Testing MFA with pilot groups before enabling it more widely to refine the process. The goal is to improve security by requiring multiple verification methods like mobile apps or phone calls when logging in remotely.

1. Implement AZURE Identity
Management Multi-Factor
Authentication (MFA)

2. Azure Identity Management:
Multi-Factor Authentication (MFA)
•To improve account security and protect against phishing attacks, the Information and Innovation Office will be implementing Multi-Factor Authentication (MFA). MFA
requires multiple forms of identity verification to secure the organization against security breaches in the event a user’s County login credentials are stolen or compromised.
When logging in remotely, users will be required to complete an additional authentication step via a smart phone app, or phone call to verify their identity
•Enable Multi-Factor Authentication for all County Users accessing Applications and Services Remotely
•Phase 1: Outlook, Teams, SharePoint, OneDrive
•Phase 2: VPN, VDI, other County provided applications which may support MFA

Project Schedule

3. Azure Identity Management:
Multi-Factor Authentication (MFA)
• Email Templates and MFA User Guides have been developed
• Meetings and Coordination with SDM’s will be held prior to Departmental Deployment
• Communications and User Guides will be sent to end users, Department by Department, on a rolling basis
• MFA Guides will be posted on COIN

VIP Handling

4. Azure Identity Management:
Multi-Factor Authentication (MFA)
• Register user account with Microsoft MFA Service (open 1-3 weeks)
• Technology Announcement Email: one week before MFA Registration begins
• Scheduled Change Notification Email: The day before Registration begins, morning of, and every 3 days until
registration period ends
• User registers with the MFA Service by following step by step instructions in user guide
• The Apple and Android email client is no longer supported. End users must transition to the Microsoft Outlook App
• Note - Enable Save Contacts in Outlook App
• User may contact Technical Service Desk if questions or issues
• User must register with the MFA Service during the registration period or they will not be able to access applications
remotely after MFA has been enabled for their department

able to log in unless MFA registration has been completed
• Will be prompted to MFA when accessing applications remotely
