For security reasons, Impact Computing cannot assist with or setup your two factor authentication for you. If you lose your mobile device, or access to your apps/mobile telephone number you will need to contact your designated IT Contact or a Company Director to instruct Impact Computing to temporarily reset your 2 Factor Authentication.
What is two factor authentication?
Two factor authentication (also called multi-factor authentication) is a way of securing your Office 365 account from malicious third parties by having a two stage logon process. On top of requiring your password to log in, a secondary verification method is used to ensure the login is legitimate.
This can be achieved in a number of ways:
1) A call to a phone number you specify, by an automated system, that gives you a code to login
2) A text message to a phone number you specify that gives you a code to login
3) A notification that pops up on your mobile phone so you can click "Approve" to approve a login
4) A specific mobile app/third party app that you generate a code in on demand.
As part of this setup, you can choose one or more than one of these methods.
How will this help secure my account?
Even though an attacker could potentially get hold of your password, they would still be prevented from logging in as they require access to your mobile phone application/SMS or Phone number that is setup thus preventing access to your account.
How do I set it up?
Once Impact Computing have enabled this for your user account, the following Microsoft article will show you how to set this up: Microsoft - Setting up Two Factor Authentication
I am using a third party app to get my e-mails, how will this affect me?
It may be necessary to create something called an "App Password" that you can use for applications where two factor isn't supported or used. This "App Password" when used to login to your account, will bypass the need to provide two factor authentication. If your e-mails are in a third party app, you will need to set one of these up.
This app password, when generated, should be entered in to your third party application; make sure you allow the app to remember the password. You absolutely should not store this password anywhere. You do not even need to remember it as another one can be generated, if needed, using your standard login password.
