Hello,
The customer journey of the platform requires to fill in a questionnaire before getting a plan based on your questionaire.
How can I let users complete the full questionnaire without creating an account?
After they finish, they should reach a login/sign-up screen before the plan is revealed.
Their answers must be preserved through authentication so they continue directly to their completed plan.
What is the best technical flow to implement this securely and reliably?
Thank you
