Can I use Microsoft Multi-factor Authentication (MFA) without a smartphone?
Yes. Although the Microsoft Authenticator app is usually the most convenient option, if you don’t have a smartphone, a cell phone with SMS text capability is the next most convenient option. Another option is to receive a voice call to one or more designated telephone numbers.
Can I set up my office phone for authentication?
Yes, you can use a land line phone, such as your office phone, but please be aware that you will need access to this device meaning this will only work if you have access to your physical phone (working inside the office). We recommend that you have an alternative device, such as a cell phone or tablet, to ensure that you can authenticate while out of the office, such as at home, in a meeting or on trips.
Can I use my current authentication app instead of Microsoft Authenticator?
FSU recommends and supports Microsoft Authenticator for use with Microsoft Multi-factor Authentication (MFA).
Some 3rd party authenticator apps may also work with Microsoft Multi-factor Authentication. However, FSU cannot guarantee compatibility or support if you use a different authentication app.
What happens if I don't set up Microsoft Multi-factor Authentication (MFA) for my Office 365 account?
Once your account is enabled for Microsoft MFA, the next time you sign in you will be directed to set up Microsoft MFA. You will not be able to regain access to your account until the MFA setup has been successfully completed.
Can I use my FSU or personal email to sign in with Microsoft multi-factor authentication (MFA)?
Email is not a supported Microsoft multi-factor authentication (MFA) sign-in method. Supported sign-in methods include the Microsoft Authenticator app, SMS text messages and voice telephone calls.
A separate Microsoft enhanced security feature called two-step verification works only with Microsoft personal accounts and not with Microsoft school/work accounts assigned to you by FSU.
What should I do if I don't have my Microsoft Authenticator mobile device with me?
See I do not have my mobile device with me on the Microsoft website for verification alternatives.
Does my phone need Cellular or WiFi access to the Internet to sign in using Microsoft Authenticator?
While the convenient pop-up (push) notification/approval feature of Microsoft Authenticator requires Internet access to function, an alternative Microsoft Authenticator sign-in procedure is available when Internet access is not available.
If you’ve previously set up Microsoft Authenticator, you do not need Internet service to sign in. Instead, you can:
- Begin the sign-in to Microsoft 365 as usual.
- In the Approve sign in request window, click on Sign in another way.
- In the Verify your identify window, click on Use a verification code from my mobile app.
- To display the one-time code in the app, click on your account in the first window. Note -- the code expires, so make sure to enter it and sign-in prior to its expiration. Otherwise you'll have to repeat steps 2-4.
- Enter the one-time code into Microsoft 365 to continue the sign-in process.
Is Microsoft’s passwordless authentication option available?
No, Microsoft’s passwordless authentication is not compatible with single-sign on technology like FSU Login.
