In Sweden there’s at least one more competitor to BankID called Freja. There’s also some kind of EU-level system.

Would be cool if multiple actors were allowed and shared the same kind of auth signing method so that there aren’t just one point of failure. Or something distributed like a blockchain type of signing method, at least I don’t think Bitcoin or Ethereum have downtime that often, and authorization should probably be read heavy only to check if some identity is still allowed
