Meridix Two Factor Authentication provider configuration

From the October release 2020 the Meridix Platform support two-factor authentication through e-mail (SMTP), OTP (Authenticator apps such as Microsoft Authenticator or Google Authenticator) or SMS (twilio (SMS SaaS vendor)), or SMPP (smpp).

The following providers are available: otp, twilio, smpp and email and the configuration is done through the standard property provider system. The 2FA can be configured on system-, reseller-, or customer level but not on the user level.
The system can and should have at least two providers set (not required). To disable 2FA completely do not set any providers at all.

Property key	Valid values (bold=default)	Description
security.two_factor_authentication_required	true \| false	Should the system enforce two factor authentication on system/reseller/customer level
security.two_factor_authentication_scope	none \| all \| admin \| system \| system-admin	For who should the system enforce two factor authentication. Options: all \| admin \| system. Is only used when [security.two_factor_authentication_required] is set to tru none = No users all = All users admin = All admin users (customer and system level) system = All system level users (reseller managers, system manager and system administrators) system-admin = All system administrators (not reseller manager and system managers)
security.two_factor_authentication_provider_types	email\|otp\|twilio\|smpp empty = no 2FA support	The enabled two factor authentication provider types delimited by \|. Options: twilio (SMS), email (SMTP). otp = Use OTP Authenticator apps twilio = Use Twilios SMS service (see section below for required provider specific configuration) email = Use the default SMTP for sending the 2FA verification code smpp = SMPP server (see section below for required provider specific configuration). Note that the order is important i.e. if both twilio and smpp is configures the first one will be used for SMS.
security.two_factor_authentication_valid_for_minutes	-1 \| integer	The time between two factor authentication requests. I.e. if the user have previously logged in the within the last X minutes the 2fa step is skipped. -1 will force 2FA on every login.

twilio

https://www.twilio.com/

<add key="twilio.account_sid" value="AC089df37bc21bd4f6d************"/>
<add key="twilio.from_number" value="+12183*******"/>
<add key="twilio.token" value="3781c88e7e1989a799********"/>

email

A provider for sending E-mails using the standard SMTP service in Meridix. No additional properties needed other than the standard SMTP configuration.

smpp

A provider for sending SMS using an SMPP server (needs to be provided by the customer). The required properties for the smpp provider is listed below.

<add key="smpp.host" value="host or IP" />
<add key="smpp.system_id" value="system-id-here" />
<add key="smpp.password" value="password-here" />
<add key="smpp.port" value="port-here" />
<add key="smpp.system_typ" value="system-type-here" />
<add key="smpp.default_service_type" value="default-service-type-here" />
<add key="smpp.source_phone_number" value="source-number-here" />
<add key="smpp.remove_country_code" value="true|false" />

Some SMPP servers do not support country code prefixes in the phone numbers set smpp.remove_country_code to true to support such scenarios.

To configure the SMPP in general, we need the host IP, password, port, and source phone number.
