As soon as you’ve decided which subscription model you want to use and have set everything
up, your next step is to configure the service and get started with some management tasks.
First, however, you’ll need to sign in. When you access Office 365 for the first time, a Welcome
page appears. Follow these steps to complete the first-time sign-in process:
1. Enter the requested basic information about who you are and where you’re located Click Next to continue.
2. Create your user ID and password, which you'll use to access the
service. Enter a user name (such as admin) and the domain name. Then create your
password. Enter your password a second time for confirmation, and click Next.
IMPORTANT Make sure you establish a strong password policy for all users. Strong
passwords use a mix of uppercase and lowercase letters, numbers, and special characters such as the asterisk or dollar sign. Learn more about creating strong passwords at
aka.ms/secure-password.
Notice the box to the right of the User ID box. It contains a blank space followed by the
text .onmicrosoft.com. This text is part of a domain name that Microsoft automatically
creates when you sign in to Office 365 for the first time. You provide the rest of the
domain name by typing it into the blank space in the box. For example, suppose your
company is called eAcademy. In that case, you might enter eacademy in the blank
space. The domain name would then be eacademy.onmicrosoft.com.
3. On the next page, select either Send Text Message or Call Me. Depending on what you choose, you will receive either a text message or a phone call
to confirm that you are who you say you are and to create a valid account. Enter your
phone number. Then, depending on which option you chose, click Text Me (as shown
here) or Call Me.
After you enter the required information, you will receive a verification message via a
text message on your phone. When you do, click Create My Account on the verification page.
