Connecting AssistMyTeam Apps to SharePoint with Office 365 account enabled with Multi-Factor Authentication (MFA)

If your admin has set up 2-step verification or multi-factor authentication (MFA) on your Office 365 account, and you’re trying to connect AssistMyTeam add-in to your SharePoint Online site, you may get the following error message in the login dialog box of the add-in if you use your Office 365 account password.

REASON: When MFA is enabled on Office 365 accounts, users are required to acknowledge a phone call, text message, or app notification on their smart phones after correctly entering their passwords. They can sign in only after this second authentication factor has been satisfied. However, for client apps such as AssistMyTeam Add-ins, this creates an overhead for users. This is where an app password comes into use. An app password is a code that gives an app or device permission to access your Office 365 account and bypass the multi-factor authentication and continue to use their application.

Generate an app password

Sign in to Office 365 (https://portal.office.com/account) using your account password and verification code using your web browser.

Click Settings > Office 365.

Click Security & Privacy > Additional security verification.

Choose Update my phone numbers used for account security. This will display the following page:

At the top of the page, choose app passwords. Choose app passwords

Choose create to get an app password.

Choose copy password to clipboard. You won’t need to memorize this password. TIP: Give a meaningful name of the app password when it prompts you. For example, you might name it “AssistMyTeam Add-in”

From your Outlook, go to the AssistMyTeam add-in that you want to connect to SharePoint Online with your Office 365 account. When prompted to enter a password, paste the app password in the box. And don’t forget to check ‘remember’ option (bottom section) so that you don’t have to perform the same steps over and again.
