Helping Hand Questions for Identity-and-Access-Management-Architect

Using Custom Login Flows with Apex is the best option to force users to authenticatewith 2FA for Salesforce only when not connected to an internal company network. Custom Login Flows allow admins to customize the login process for different scenarios and user types2. Apex code can be used to detect the user’sIP address and prompt for 2FA if it is not within the company’s network range3. The other options are not suitable because they either do not support 2FA or do not allow conditional logic based on the user’s IP address.

User Provisioning for Connected Apps allows Salesforce to create, update, and deactivate users in an external service such as Google Workspace based on user and permission set assignments in Salesforce. References: User Provisioning for Connected Apps

The best approach to simplify the authentication process and reduce cost and maintenance is to configure UC1 as the Identity Provider to the other four Salesforce orgs and set up JIT user provisioning on all other orgs. This way, users can log in to any of thefive orgs using their UC1 credentials, and their user accounts will be automatically created or updated in the other orgs based on the information from UC11. This eliminates the need to purchase a third-party Identity Provider or manually provision users in advance. The other options are not optimal forthis requirement because:

Purchasing a third-party Identity Provider for all five Salesforce orgs would incur additional cost and maintenance, and would not leverage the existing user base in UC1.

Not setting up JIT user provisioning for other orgs would require manually creating or updating user accounts in each org, which would be time-consuming and error-prone. References: Salesforce as an Identity Provider, Identity Providers and Service Providers, Just-in-Time Provisioning for SAML

 OAuth refresh token flow and OAuth JWT bearer token flow are the recommended best practices for using OAuth flows inthis scenario. These flows are suitable for server-to-server integration scenarios where the client application needs to access Salesforce resources on behalf of a user. The OAuth refresh token flow allows the client application to obtain a long-lived refresh token that can be used to request new access tokens without requiring user interaction. The OAuth JWT bearer token flow allows the client application to use a JSON Web Token (JWT) to assert its identity and request an access token. Both flows providea secure and efficient way to integrate with Salesforce and the reward calculation system. OAuth SAML bearer assertion flow is not a recommended best practice for using OAuth flows in this scenario because it requires the client application to obtain a SAML assertion from an identity provider, which adds an extra layer of complexity and dependency. OAuth username-password flow is not a recommended best practice for using OAuth flows in this scenario because it requires the client application to store the user’s credentials, which poses a security risk and does not support two-factor authentication.
