# Using Microsoft Authenticator to log into Office 365

You will need to have already completed the Multifactor authentication enrollment and/or have the Multifactor Authenticator app set up on your phone. You will be prompted to authenticate your trusted device by approving the popup request, call or text on your phone or tablet/iPad.

1. Go to https://myseneca.ca[Office 365](https://myseneca.ca) \(email, SharePoint, OneDrive, etc.\) in your computer or phone.https://myseneca.ca
2. Enter your **Seneca email address** and click Next
3. Enter your **password** and click Sign In
4. Click Next
5. A pop-up request will appear asking you to Verify your identity. Microsoft 2FA authentication is required for every log in attempt. Select your authentication method.

    - If you're using the Multifactor Authenticator app, a notification will be delivered to your smartphone. Tap APPROVE within 30 seconds or enter the number shown to sign in before the notification expires and the Multifactor Authenticator app will be dismissed.
    - If you're using the verification code from the Multifactor Authenticator app, enter the passcode and continue.

7. You will now be successfully logged in.

Note – if the Multifactor Authenticator app produces an unexpected authentication prompt \(for example, when you have not attempted to log in recently\) you can either tap DENY or ignore the prompt and access will not be granted or contact [ITS Service Desk](https://students.senecapolytechnic.ca/spaces/190/support/wiki/view/1473/contact-its). However, this may be an indication that your account has been compromised so you should change your password immediately at https://myid.senecapolytechnic.ca.
