BankID is _in theory_ a nice technology. However, it is only handed out to people registered with the Swedish tax authorities holding a Swedish bank account.
All daily activities are nowadays bound to BankID: need a doctor's appointment? -> needs BankID; Want to buy something on Blocket? -> needs BankID.
As an European frequently spending some time in Sweden not in possession of a Swedish tax #, I feel very much excluded from online and partially offline activities in this country.
But on the plus-side the Swedish state-eID solutions is planned to be delivered by end of year and hopefully most organizations will start migrating or at least dual-supporting them and in doing so also fix their services to support foreign eID's in the process.
Sure a 24h delay or SMS code are 2 way but they fully fall into the bandaid category.
In the past we used to have disconnected dongles for banking, the bank issued a one-time challange and you entered the response along with your username. Now there are disadvantages with those also but at least it was fully airgapped.
