A login flow in Salesforce is a process that allows users to authenticate their identity and gain access to the Salesforce platform. The login flow can be customized to meet the specific needs of an organization, including adding additional authentication steps, such as multi-factor authentication (MFA) or single sign-on (SSO) integration.
Lets take and example to understand this in more details
In this example, we will create a simple login flow for a Salesforce organization that requires users to enter their username and password, and then pass a MFA check using a code sent to their email.
Step 1: Create a new login flow by going to Setup > Process Automation > Flows. Click on the “New Flow” button.
Step 2: In the Flow Designer, add a “Screen” element and name it “Login Screen”. Add two “Text Input” elements to the screen, one for the username and one for the password.
Step 3: Add a “Decision” element to the flow and name it “Authenticate User”. This element will check the entered username and password against the Salesforce user database. If the credentials are valid, the flow will proceed to the next step. If the credentials are invalid, the flow will return to the login screen with an error message.
Step 4: Add a “Record Lookup” element to the flow and name it “Retrieve User Email”. This element will look up the email address of the authenticated user in the Salesforce user database.
Step 5: Add a “Screen” element and name it “MFA Screen”. Add a “Text Input” element to the screen for the MFA code.
Step 6: Add a “Decision” element to the flow and name it “Verify MFA Code”. This element will check the entered MFA code against the code sent to the user’s email address. If the code is valid, the flow will proceed to the next step. If the code is invalid, the flow will return to the MFA screen with an error message.
Step 7: Add a “Screen” element and name it “Welcome Screen”. This screen will display a message to the user indicating that they have successfully logged in.
Step 8: Activate the login flow and assign it to the appropriate profiles or permission sets.
This is just a basic example of a login flow in Salesforce. Additional steps can be added to the flow, such as integrating SSO or using a third-party MFA service.
