How to enable strong authentication (MFA)

In Jamk we require strong authentication in several services. Strong authentication (MFA) allows safer login to services, as it makes it possible to prevent access to O365 account even if the ID/password is compromised. In addition to regular username and password, a separate confirmation is required using mobile app. Alternative ways are a one-time code, a text message, or a phone call. More details about why MFA is necessary can be found here.

Things to notice

After enabling MFA, some old, incompatible applications may not work. Such can be for example some phone manufacturers own customized email applications.

Jamk’s ICT services recommends following supported and tested applications:

  • Windows: Office 2016 or newer, Microsoft 365 Apps for enterprise (formerly known as Office 365 proplus)
  • Android: Microsoft Outlook
  • MacOS: Apple Mail 12 or newer, Office 2016 or newer, Microsoft 365 for Mac
  • iOS: Microsoft Outlook

General introduction to enabling MFA

  • Enabling MFA only takes few minutes.
  • You will need a mobile device to which you want to send MFA confirmation messages.
  • After starting the process, you will have few minutes to complete it. If this is not done quickly enough, the deployment may fail and the process will need to start over.

Instructions for implementing MFA:

You can enable MFA for your account by logging in to Microsoft 365 and then following instructions given there. You might also want to check frequently asked questions at the end of this page.

This page explains process with more details. You can configure MFA either by using only mobile phone or by using a combination of mobile phone and computer. For instructions on both different methods below, select the one you want.

  • New phone or problems with Authenticator app?

    You can add new authentication method for your Office365 account at It is recommended to remove any unnecessary/unused authentication methods to keep your account secure (E.q your old mobile devices that you no longer have access to).

    If you no longer have access to your Authenticator app or it’s not working, you will need to reset your account MFA settings using these instructions.

    Here are few common questions/answers (FAQ).

    • How do I log in, when MFA is enabled?
      • You log in to the service with your username and password like you are used to and then you also accept a notification on your phone. If for some reason the notification does not appear automatically, open Microsoft Authenticator application. The request should show in the application. After entering the ID, you have about one minute to accept it on your phone.
    • I received authentication request on my phone even though I wasn’t actually logging in to any service, what do I do?
      • Deny unknown login requests! However, confirm that none of your devices is not trying to log in to the service, such as your phone’s email application. Suspicious logins should be reported to Jamk ICT services, so that they can check where the login attempt came from. 
    • I’m about to change my phone, what should I do?
      • Set up your new phone and follow these same instructions. Once Microsoft Authenticator is set up on your new phone and your account is linked to it, you can wipe and discard your old phone.
    • My phone was stolen/lost/broken, how can I reset my MFA settings?
    • I want to use my personal phone to accept logins, how do I do that?
      • No problem, you can install and link Authenticator App also to your personal phone. Go to and click “Set up Authenticator app” -button. Set up authenticator app The process is the same as when you did this for the first time with your corporate phone. After this is done successfully, confirmation messages will appear on all linked devices (it doesn’t matter which one you use to accept the sign in message).
    • Where can I check what devices I have linked to my account to use for MFA logins?
    • Why is MFA approval not required every time, and why on the other hand, does it sometimes happen more often than I would like?
      • There is no simple answer to this, but there is a multi-level risk assessment in the background that may require additional verification occasionally.
      • Local network on Jamk campus area is configured as trusted network, where we allow login just by using regular username and password without MFA.
    • Why do I get a verification message on my phone even when I sign in to service “X” that is not on O365? ?
      • Some third-party services are connected Jamk’s O365 sign-in and these are subject to same MFA requirements. These are some some personnel/financial management services and also electronic signature service. Also systems that use HAKA login, like Peppi and Moodle require strong authentication.
    • Why did my phone stop synchronizing emails/calendar after enabling MFA? Why did I receive a message saying that IT-department has blocked access to my email?
      • Some email apps require user to first remove and then add the synchronization account again from phone settings. Only after this it knows that it has to use strong authentication.
      • After enabling MFA, some old, incompatible applications will not work. Such can be for example some phone manufacturers ’own email applications. In this case, install Outlook from app store.
    • Why is location information displayed in Authenticator not accurate?
      • Location information displayed in Authenticator is only informational. It is based on network address and it is not very accurate. If you are logging at Jyväskylä and map shows that you are in Tampere, its is not alarming, but if you are in Finland and map shows login from some other continent, then you know something is probably wrong.
