about session attributes and authentication of user

Question

Actually i am not clear yet. In my scenario I have created an authentication  intent . for other intent like transaction related intent if the user directly hit those transaction related intent it should ask first authentication like username , mobile and email. also i want that if the authentication happened for one time then it should not ask for other intent .

Answer

1. You can use a session attribute to see if the customer is authenticated already or not. 
2. Use conditional branching to branch the conversation based on if the customer is authenticated. (https://docs.aws.amazon.com/lexv2/latest/dg/paths-branching.html)
3. If the customer is not authenticated. Save the name of the current intent in an attribute (so you know where to go back to later).
4. You can switch to the authentication intent (https://docs.aws.amazon.com/lexv2/latest/dg/paths-nextstep.html)
5. When the user is authenticated. Update the attribute you use for authentication (Now that it is set to true, other intents won't have to transfer to the authentication intent).
6.. When the user has been authenticated, look at the attribute where you saved the intent name you came from and switch back to it.
