Once your IT administrator enables your organization with multi-factor authentication (MFA for short and also sometimes called 2-step verification), you have to set up your account to use it. By setting up MFA, you add an extra layer of security to your Office 365 account. First, you sign in with your password (step 1) and then a code is sent to your phone (step 2).
- Sign in to Office 365 with your work or school account with your password like you normally do. After you choose Sign in, you’ll see this page:
- Choose Set it up now.
- Select your authentication method and then follow the prompts on the page.
- After you verify your alternate contact method, choose Next.
- You’ll get an app password that you can use with Outlook, Apple Mail, etc. Choose the copy icon to copy the password to your clipboard. You won’t need to memorize this password.
- Once you complete the instructions to specify how you want to receive your verification code, the next time you sign in to Office 365, you’ll be prompted to enter the code that is sent to you by text message, phone call, etc.
To have a new code sent to you, press F5.
We strongly recommend setting up more than one verification method. For example, if you travel a lot, consider setting up Microsoft Authenticator for your verification method. It’s the easiest verification method to use, and a way to avoid text or call charges.
To use the app password in Outlook
You will only need to do these steps once.
- Open Outlook, such as Outlook 2010, 2013 or 2016
- Wherever you’re prompted for your password, paste the app password in the box. For example, if you’ve already added your account to Outlook, when prompted paste the app password here:
- Or, if you’re adding your Office 365 account to Outlook, enter your app password here:
- Restart Outlook.
