The first time when logging into your Chatham email, you will be prompted to set up your MFA. This is mandatory and cannot be skipped. This will ensure that your log in is secure.
After logging in click Set it up now.
On the “additional security verification” setup page that opens, you will now choose the contact method you prefer for MFA. Here is a brief description of each method:
a. Authentication Phone – receive either a voice call or a text message at the phone
number you provide.
b. Mobile App – Using the “Azure Authenticator” app for your iOS or Android device,
receive a verification code or notification.
Select your preferred contact method and follow the appropriate instructions on the next page for the method chosen.
Authentication Mode ‐ Authentication Phone
1. After specifying “Authentication phone” as your preferred contact method, specify your mobile phone number using the appropriate country code prefix. Then choose the appropriate mobile phone contact method you prefer, either “Send me a code by text message” or “Call me”. Click Next when complete.
2. You will now receive either a call or a text message with a verification code to complete the
setup. If you chose to receive text messages, enter the verification code you received and click
Verify. If you chose to receive a call, you will receive an automated call prompting you to press
the # key to complete verification.
3. You’ve now completed setup of multi‐factor authentication. Please jump to the end of this guide to the section entitled “Signing in with MFA” to learn about the new sign in experience.
Authentication Mode – Mobile App
1. After specifying “Mobile App” as your preferred contact method, choose how you would like to interface with the mobile app by either selecting “Receive notifications for verification” or “Use verification code”. Here is a further explanation of each option:
- a. Receive notifications for verification – The mobile app will display a prompt asking you to approve or deny login. You do not have to open the app for this to occur, it will
happen automatically when you sign in to Office 365.
- b. Use verification code – When signing into Office 365 and prompted for MFA, you will need to open the app on your mobile phone and type in the current code displayed.
Note that this code changes every 30 seconds.
2. Select your preferred mobile app authentication method and click Next to continue setup.
3. Regardless of the authentication mode you prefer, you will need to download and install the
“Azure Authenticator” app from your mobile device providers store. Once downloaded, open
the app and click the + sign to add your account. You’ll be prompted to specify the type of
account you are adding. Choose “Work or school account”.
4. The app will then prompt you to point your mobile devices camera to the QR code displayed on your computer screen. Once captured the mobile app has completed setup.
Note: If you cannot use the camera to capture the QR code on your monitor, you can manually enter the code and URL displayed on the screen into the mobile app. Click Next to finish configuration.
5. You should now see a message on the computer signifying that the Mobile app has been
configured for notifications and verification codes. Click Next to complete MFA configuration.
6. The mobile app will now verify configuration by either sending a notification request or
prompting you to enter the current security code based on which authentication method you
chose. Follow the steps to either approve the notification or input the current security code.
7. Once verified, the computer screen will ask you to input a mobile phone number as a backup in case you lose access to the mobile app. Input your mobile number, then click Next.
8. In step 4, you will be shown an App Password. Copy this password to a safe location and keep it readily available. You will need this app password for applications that do not support modern authentication such as the built‐in mail clients on Android and iOS devices. When signing into legacy applications and services that do not support modern authentication, use this app password to authenticate.
9. Click Done to complete setup.
Signing in with MFA
1. When signing into Office 365 via a web browser for the first time after configuration MFA, you will see a screen similar to the following:
TIP: Clicking the “Don’t ask again for 30 days” will remember the MFA for this device for 30 days. This is a good idea to enable if you are on a device you use every day. If you are signing into a device for the first time and don’t intend to use it again in the future, leave this box unchecked.
2. Using the authentication method configured previously, authenticate either via phone, text
message or the Azure authentication app. Once you’ve provided the second form of verification,
the login will complete, and you will be automatically taken to your Office 365 services.
