It is an issue that digital identification in Sweden is run by a single private company. The drawbacks are not clearly seen from a consumer standpoint, but they do charge service providers for each login, and can set their prices freely since it's a monopoly.

They also have rules against being logged in for too long, and against identity transfer (directly or indirectly using BankID to authenticate for a different login method) [1], since that would result in fewer BankID logins and less revenue for them.

One result of the latter restriction is that any letters containing authentication codes need to be sent by physical mail, since all digital mailboxes such as Kivra and the government-run "Min myndighetspost" support login by BankID. The University Admissions service (antagning.se) were forced to stop sending codes through digital mailboxes due to this [2].

That’s some good arguments, I change my mind.

Those sound like good rules?

Are you sure they can set the prices "freely"? Many regulated monopolies like this are restricted in their pricing.

If you lose the device key on your computer (perhaps there is a hardware error or it is stolen), you can use the paper key to add a new device key to your account - and not lose any data.

You can add another paper key using `keybase paperkey`, and you may want to revoke the old one using `keybase device remove <key name>`. This is also possible to do from the "Devices" tab in the desktop or mobile app.

Of course, if you have Keybase both on your computer and your phone you already have some redundancy, and maybe having a paper key is not as important.
