Sign in to my Microsoft 365 account
Step 2 of the Set up my Microsoft 365 account series.
Sign in to access your Microsoft 365 account. Bookmark the sign-in page for easy access from your web browser.
- Go to the Microsoft 365 sign-in page.
 - Enter your Microsoft 365 email address and password (your 123 Reg username and password won't work here).
  Note: If your web browser auto-fills your username and password, make sure it's using your Microsoft 365 email address and password, not your 123 Reg account credentials.
  
   - (Optional) To stay signed in to your account when you close and reopen your browser, next to Keep me signed in on this device, select the checkbox.
 - Select Sign In.
 - If you’re signing in from a new device or location, you’ll see a prompt to Verify it’s you and confirm your identity through a one-time code.  
  
   - If you're asked to trust your domain, select Continue.
      
   - If it's your first time signing in and multi-factor authentication (MFA) is enabled, you'll see a prompt to set up your authentication method. (If you have trouble following the on-screen instructions, trying setting up MFA using these steps instead.)
 - If you already have MFA set up, verify your identity using your authentication method.
 - On the M365 Copilot page, on the leftmost side, select Apps.
    
   - To open your email, select Outlook.
  
- If you see a prompt that says your email is used with more than one account with Microsoft, select Work or school account (not Personal account).
