Suggested Answer: 
    

Box 1: Guest3 only -
When does a guest user get a one-time passcode?
When a guest user redeems an invitation or uses a link to a resource that has been shared with them, they'll receive a one-time passcode if:
They don't have an Azure AD account
They don't have a Microsoft account
The inviting tenant didn't set up federation with social (like Google) or other identity providers.
Box 2: 30 minutes -
One-time passcodes are valid for 30 minutes. After 30 minutes, that specific one-time passcode is no longer valid, and the user must request a new one. User sessions expire after 24 hours. After that time, the guest user receives a new passcode when they access the resource. Session expiration provides added security, especially when a guest user leaves their company or no longer needs access.
