Hi Gildas, thanks for joining the conversation!

You are correct that, up to now, we have treated storage of tokens as out of scope for Payment Request API and Payment Handler API. They define
a pipe through which data flows, but what parties do with that data and how they store it is up to them.

I anticipate that we will discuss both subscriptions and 3DS at our upcoming face-to-face meeting [1]. Is there any way for you to attend (or for Lyra to otherwise
be represented)?
