Hello,
I'm migrating our software from long-lived access tokens to short-lived ones with refresh tokens.
My main question is is it possible to do the transition for a user who already has a no expiration token to refresh tokens without asking him to authenticate again.
As a secondary question - I asume expires_in is second, but can you please confirm this since I cannot seem to find the unit in the documentation.
Thank you in advance,
Nikola Simeonov
