Verify Your Microsoft Account

The first time you sign in to Microsoft 365, you'll be asked to set up a second way to prove it's really you. This protects your email and files if your password is ever stolen.

ℹ️
You'll verify with your mobile number — a text message code or an automated phone call. Have your phone with you before you start.

Set up phone verification

  1. On a computer, go to office.com and click Sign in. The office.com welcome page with the Sign in button
  2. Enter studentID@imco.edu.om and click Next. Microsoft Sign in screen with a student email address entered
  3. Type your password and click Sign in. Enter password screen on the IMCO sign-in page
  4. At “Let's keep your account secure”, click Next. Let's keep your account secure screen with the Next button
  5. On the “Install Microsoft Authenticator” screen, do not install the app — click Other options at the bottom. Install Microsoft Authenticator screen with Other options highlighted
  6. Under “Add a sign-in method”, choose Phone. Add a sign-in method list with Phone selected
  7. Set Country code to Oman (+968), type your mobile number, then choose Text me a code or Call me. Click Next. Add your phone number screen with Oman +968 country code
  8. If you chose text: type the code from the SMS and click Next.
    If you chose call: answer the automated call (it comes from a +1 number) and press # on your phone keypad when asked to confirm. Phone call screen showing the hash key to press to confirm
  9. When it confirms the number was added, click Next → Done.
💡
If you can, add a second phone method too (for example one text and one call) so you're not locked out if one doesn't come through.

From now on

Each time you sign in to a Microsoft service on a new device or browser, Microsoft sends a code by text — or calls you. Enter the code, or answer the call and press #, to finish signing in.

⚠️
Only enter a code, or accept a call, for a sign-in you just started. If you get a code or call you didn't ask for, don't use it — and change your password from a campus computer.
