@testuser7 Thank you for reaching out to us, As I understand you are looking for detailed explanation on this - A PRT is valid for 90 days and is continuously renewed as long as the device is in use. However, it's only valid for 14 days if the device isn't in use.
Hope this explains -
90-Day Validity: A PRT is valid for 90 days if the device is continuously in use. During this period, it gets continuously renewed to ensure that the user remains authenticated.
14-Day Validity: If the device is not in use, the PRT remains valid for only 14 days. After this period, the user will need to authenticate again to obtain a new PRT.
Let me know if this answers your question, feel free to post back.
