Note: When you sign up for a Microsoft 365 subscription, previously known as Office 365, transferring your existing contacts and calendars from your current email client to your new Microsoft 365 account is important. This ensures that your important dates and contacts are seamlessly integrated and accessible within your new Microsoft 365 environment, helping you stay organized and connected with minimal interruption.

Set up Multifactor Authentication for Microsoft 365

Multi or two-step verification significantly bolsters the security framework for Microsoft 365 users. Requiring a secondary form of verification ensures that simply knowing a user's password isn't enough for access; a unique code sent to the user's mobile phone is also needed. This dual layer of security effectively creates a more robust barrier against unauthorized access, making it much harder for hackers to enter accounts.

Starting in 2020, Microsoft has made it mandatory for users to set up multifactor authentication for Microsoft 365 to use Microsoft 365 services. This move underscores the importance Microsoft places on security and the lengths it's willing to go to protect user data. Setting up MFA is a straightforward process that needs to be initiated by the admin panel. It's important to note that this setup cannot be done on the customer's behalf. However, ample resources and step-by-step guides are available to assist customers through the process. This ensures that users are protected and supported throughout the setup process, making the transition to a more secure system as smooth as possible.

To enhance security within the organization, enabling multifactor authentication (MFA) for all our Microsoft 365 accounts is vital. Here's how to go about it:

For the Admin User

The first step involves the admin user logging into the Microsoft 365 admin center. The purpose here is to enable multifactor authentication for the entire organization. To accomplish this, refer to Microsoft's official documentation titled Set up multifactor authentication for Microsoft 365. This document provides detailed, step-by-step instructions to seamlessly guide you through the process.

For Each Microsoft 365 User

Once the admin has enabled multifactor authentication, each user within the organization must set up two-factor authentication for their individual account. To do this, users should log into their Microsoft 365 accounts and follow the steps outlined in Microsoft's Set up your Microsoft 365 sign-in for multi-factor authentication documentation. This guide will walk you through the setup process to ensure your account is secured with multifactor authentication.

If you do not save the App password in the steps above, you can reference Using app passwords with apps that don't support two-step verification to reset the App passwords and connect your email clients (such as Outlook, Thunderbird, Apple Mail, iPhone, iPad, Android, and Tablets).


To maintain uninterrupted access and bolster security for Microsoft 365 accounts, admin and individual users within an organization must promptly set up multifactor authentication for Microsoft 365. This proactive measure ensures compliance with Microsoft's mandatory security requirements and significantly reduces the risk of unauthorized account access. Following the outlined steps to enable MFA will help users protect their data and continue to benefit from the services without disruption.
