Multi Factor Authentication - MFA - 2FA

Figure 1:
GraceOhio Login 2FA Approval Process with phone app msedge_yWMBg7J3Cc.gifimage-1653511204994.gif

Grace IT is rolling out and enforcing this MFA policy to all Staff in order to improve the security of our organization and help reduce potential headaches. If you are enrolled in MFA, you will need to have your phone as an additional method of authenticating yourself (on top of your password) to log in to your Work Office365 account. The easiest way to do this is by using the Microsoft Authenticator App on your phone with push notifications; however, you can use a different method or authenticator if you prefer.

The benefits of being enrolled in MFA is that you do not have to worry about resetting your Work Office365 and Work laptop password regularly, and you will not get any more password reset notifications/emails. MFA also makes it increasingly difficult for anyone else to access your account since they need your password and your approval from your phone in order to sign in, making this a critical technology in cybersecurity.

Standard 2FA Method: Microsoft Authenticator (App Push Notification)

icon_microsoft-authenticator[1].png 

(This is the Microsoft Authenticator App. For more app related information from Microsoft, click on the icon.)

The default (and most straightforward and quickest) method that Grace IT sets up everyone with is the push notification through the Microsoft Authenticator App. When a sign in attempt is made to your account, a push notification is sent to your phone asking to Approve or Deny the login attempt. This method can be changed to another one, if you desire, through your Microsoft Account page. Instructions for setting up MFA using this method are listed below. Click on the dropdown arrow to expand the corresponding guide:

A passcode lock on your phone is required by our organization in order to use the Microsoft Authenticator App and the Outlook app together. You will need to setup a 4 or 6 digit passcode on your phone in order to properly use the Authenticator app. Please set this up before proceeding through the below instructions.

Setting up the method manually yourself

Expand this instruction list to get started! Use these instructions if you need to setup a new phone with the Authenticator app.

Instructions: Click on me!
1) Install the latest version of the Microsoft Authenticator app, based on your phone:
2) Configure 365 account in Authenticator App
  • With your work laptop, Sign into your Office365 at https://myaccount.microsoft.com/
  • Select Security info in the left menu or by using the link in the Security info pane. If you have already registered or been registered by IT, you'll be prompted for two-factor verification. Then, select Add method in the Security info pane.
  • On the Add a method page, select Authenticator app from the drop-down list, and then click Add.
  • On the Start by getting the app page, click Next.

  • If you are an iOS user, please read through the "Situational" section in this article.

Situational: If you are an iOS user AND use the built in Mail or Calendar App for Work:

iu[2].jpgios-mail-icon-100669537-large[1].jpg

iOS Situation: Click on me!

Unfortunately, as of right now Apple's built in Mail and Calendar apps (if you use them for work) will eventually stop working when you setup MFA! This is because they are unable to bring up the prompt for 2FA when you are already signed in (very specific technical reason on Apple's end). You will have to remove your Office 365 account and re-add it in order to keep using these apps for work. Because of this, Grace IT STRONGLY recommends you avoid using the built in iOS MAIL/CALENDAR apps and instead use the Outlook App.

If you follow these steps, however, you will be able to get these back up and running for a little while longer (Until it stops working again. You also have the option of using the Outlook App, which does not have this reauthentication issue and supports both mail and calendar functionality.) 

  • Open your settings app.
  • Scroll down and find either "Mail" or "Calendar". Tap one of them. If you use both for work, you may want to take note of your preferences that you may have setup for each.
  • Tap "Accounts"
  • Find and Tap on your Work account. It will have the graceohio/gracechurches email address.
  • Take note of the work content that you are syncing (Mail, Contacts, Calendars, Reminders, and Notes).
    Then click on Delete Account.
  • When it finishes removing your account from your phone, you should be taken back to the accounts screen. Tap on "Add Account"
  • You will see a list of email services you can select. Be sure to choose Microsoft Exchange, as Office365 accounts will only work with this and not the Outlook.com option.

    image-1624807663886.png

  • In the new screen that pops up, enter your work email here. Also put in a name for this account that you will recognize (For example: Grace Church - Work).
    • Tap Next. This will probably trigger 2FA, so you will need to approve the sign in attempt if it does ask.
  • The screen that lets you choose to sync specific content appears. Refer back to your note for what content you sync and enable those respectively. Hit next
  • Your mail/calendar/content will start syncing. This may take a minute, or if you have tons of calendar appointments/events it could take a couple hours to finish. We recommend leaving your device charging if it is taking more than a few minutes. You should be all set for the time being.

UPDATE: You may see a prompt like this picture below on your phone when roughly 60 or 90 days pass. Apple forces you to reauthenticate after that period of time but vaguely prompts you to do it with this message. PLEASE keep this in mind if you really want to use the iOS Mail app, as when the period time passes by you will stop receiving mail and calendar updates again until you reauthenticate your account again. There is not much that Grace IT can do to remedy this as this is primarily an Apple technology issue. The Outlook App does not have this issue, so Grace IT again recommends you to use that as your Mail and Calendar App solution for Work.

If you see this picture below, your iOS Mail/Calendar app wants you to reauthenticate your work account. As you can tell from reading the prompt: it vaguely tells you this—but you will need to address this prompt in order to continue receiving email and calendar updates when using the iOS mail and calendar apps for this purpose.

    • You can tap Edit Settings to re-enter your password for your Office365 account. You can also re-enter your password by going to the Settings app, then to Mail or Calendar. Tap on accounts and and tap on your work account..

Logging into GraceOhio/Microsoft Office365 Account - How it works

Once you are setup with a MFA method using one of the guides above, you can reference the same two GIF's at the top of this page and down here as well to get a general idea of the process of using the Authenticator app to login to your GraceOhio account (Reload this page if the demonstration GIF's go out of sync, synchronizing two GIF's together is really difficult). The general login process goes as follows in these bullet point steps:

a. Computer View (www.office.com for example) b. iPhone View (Using Authenticator App to approve MFA)

msedge_yWMBg7J3Cc.gifimage-1653511204994.gif

  • Goto/Open Microsoft Office365 service you are licensed for. In this case, we are logging into www.office.com in the Microsoft Edge web browser.
  • On the Login Screen, Enter your Email Address, and then Password. 
  • Upon successful credentials entry, you may need to provide MFA. In the case where you do, you will either automatically receive a push notification, or you can send it yourself, OR send a different MFA request if you set one up (ex SMS code or email code). Note that a MFA request is not required for every session. The only time you will be requested MFA are these scenarios:
    1. If you are authenticating in for the first time on the application or computer in question, OR
    2. If you logging in after 30/60/90/365 days (This number depends on the application, or what option you choose for the "Don't ask again" prompt)
  • If you receive the Push Notification, just make sure you have your phone on you. Tap on the push notification to bring up the Authenticator app, and tap approve if it is you who is trying to sign in. You will only have about 60 seconds to accept this before you need to request another MFA request.
  • All done! You can get started now!

Tips and Cautions to be aware of

Tips
  • Ensure that you keep the Microsoft Authenticator App up to date. This can help ensure that any issues or known security vulnerabilities have been patched. [For iOS users, visit How to Update iPhone apps manually and automatically. For Android users, visit How to update Android apps.]
  • On the step where you are entering your credentials, You may also have the option to sign in using the app rather than using your password via the Use an App instead method shown above. This is called a passwordless login method. You can enable it by following Microsoft's steps:
    • Browse to https://aka.ms/mysecurityinfo .
      Sign in, then click Add method > Authenticator app > Add to add the Authenticator app.
      Follow the instructions to install and configure the Microsoft Authenticator app on your device.
      Select Done to complete Authenticator configuration.
      In Microsoft Authenticator, choose Enable phone sign-in from the drop-down menu for the account registered.
      Follow the instructions in the app to finish registering the account for passwordless phone sign-in.
    • Once you have the Authenticator App setup on your phone, you can follow the this guide: Sign in to your accounts using the Microsoft Authenticator app
  • On the step where you need to provide MFA, it will also ask if you don't want to be asked again for a certain amount of time. You can check this off if you want!
  • Using the Microsoft Authenticator App method, instead of using a push notification you can provide a one-time password code provided by the app to enter in order to authenticate yourself. The code is generated every 30 seconds, and you can grab the code anytime by tapping on the GraceOhio entry in your Microsoft Authenticator app:

Cautions to take account

Please read and keep these tidbits of information in mind to help protect yourself and our church from harm.

  • Even with how strong MFA is, it is not infallible. You still need to have strong passwords.
    • MFA is only as strong as to how well you keep your phone/phone number (or email account) secured. Make sure that you keep your phone/phone account protected by strong passcodes and passwords, and make sure that your phone number is not compromised.
    • Never share a MFA token (or a session token) with anyone under any circumstance. The MFA token is a form of authentication that should only be used by the authorized user.
  • Do not accept Authentication Requests when you are not trying to login yourself. 
    • Never accept authentication requests when you are not attempting to log in yourself. Even if Grace IT is trying to log in to your GraceOhio account to assist (Grace IT can bypass the MFA step or reset your account credentials), do not accept any sign-in request that you did not initiate.
    • If you receive a MFA request when you weren't attempting to log in through a login prompt yourself, your password may have been compromised. Change your password immediately, especially if you use the same password for other internet accounts.
  • Each Microsoft Authenticator app notification is supposed to be received almost instantaneously (within a couple of seconds), and each request sent will only last for approximately 60 seconds. If you do not accept the request in time, you will need to make a new request since the verification timed out.
    • If you miss the time window for authenticating through MFA, do not accept any requests that come later than 60 seconds after you initially made the request, as they will not be coming from you (check out Figure 2). This is particularly important since hackers may send fake requests to trick you into accepting them. Again, change your password when you don't initiate a MFA request yourself.

Change or Add 2FA method

image-1664897434078.png

You can access your Microsoft Account page here. The link takes you to the security info section. Here you can remove and add methods (Phone text or call, Email, or another Authenticator App), as well as take a look at your default and current methods. You also don't have to strictly use the Microsoft Authenticator app if you prefer to use something else, but it is a solution that Grace IT recommends since it integrates well with our work environment. Once you click on Add sign-in method, choose your method and follow the onscreen instructions.

You can also follow the manual step-by-step setup guide listed earlier in this KB article for adding the Microsoft Authenticator App for MFA quickly: Setting up the method manually yourself

This resource will be useful if you ever go through the process of changing or upgrading your phone, as your Multi Factor configuration is not carried over to your new device automatically. If you see yourself upgrading your phone soon or often enough then we strongly recommend you add another method, like your phone number or personal email, using the above link so that you do not experience downtime from being locked out of your account.

If you ever get stuck, and get locked out of your account for any reason, don't panic—Grace IT will be able to reset your credentials or MFA methods for you. Reach out to Grace IT at the helpdesk: https://kb.gracechurches.org/books/it-helpdesk/page/requesting-it-help-grace-church-and-ce-national
