Is federated authentication being considered for the future? The federated model of the fediverse is great, but it runs into problems when instances “die”, you want to access different servers as they federate with different things, etc. leading to the need of having multiple accounts. If there were a decentralized network of auth servers, could use the same credentials everywhere.
Not sure about Iceland, but several countries place some constraints on which foodstuffs you can enter the country with (not asking about importing, etc, even for personal consumption). I’d check this beforehand.
