I investigated this option. It seems that in order to effectively manage recurring payments / subscriptions, we need to authenticate our users (meaning sign in / sign up).
Once we have a user ID, we can via stripe, create a stripe user for them, save (in stripe) their default payment method (using stripe customer + setup intent), and create their subscriptions.

The other thing that the user needs to be able to do is to manage the subscription (eg. have the ability to resign). For this the sign in is also required.

In order to do this, we need to integrate with (the most supported one would be) Sign in with Apple.

Considering that each Apple user has an AppleID, we should probably go forward with that.

I estimate a few days of my time. Let's say 4.

@Popolechien you'll have to decide if it's worth it and when to implement it

Ok let us put this on hold until 6 months after launch of the single-support option so we can assess the likelihood (and RoI) of getting recurring donors.
