Two Factor Authentication
IntelliSent is ready to provide two factor login, but it's disabled as default. You can easily enable it in host settings page (in Security tab):
Note: In a multi-tenant application, two factor authentication is available to tenants only if it's enabled in the host settings. Also, email verification and SMS verification settings are only available in the host side. This is by design.
When it's enabled, user is asked to select a verification provider after entering user name and password:
Then a confirmation code is sent to the selected provider and user enters the code in the next page:
Email Verification
This is available if user has a confirmed email address. Since email sending is disabled in debug mode, you can see the code in logs. In release mode, email will be sent.
SMS Verification
This is available if user has a confirmed phone number. In order to validate a phone number, a user should open my settings modal as explained in here. When the user enters the phone number, a button will appear to validate to phone number. When the validate button is clicked, an SMS message is sent to entered phone number including a validation code and another modal window is opened for entering the validation code. When user enters this validation code, the phone number for the user will be set as validated.
