If you do not have MFA enabled for your Office 365/Azure AD account you can enable it trough following link https://aka.ms/mfasetup or use conditional access policy to enforce MFA for user accounts.

Only push message trough Microsoft Authenticator App or phone call can be used for 2-factor authentication with SSL VPN/Sophos Connect. To prevent users for selecting any other possible multi-factor authentication method you should disable verification options that are not supported.
