No you use the bankdosa, go to the bank or your working bankid when you want a new bankid on a new device.
To renew the bankid you use the bankid you have to renew it while it’s still valid.
I did add a new bankid with a valid bankid a month ago and i tried bankdosa on my bank yesterday but i didn’t go through all the steps but i did get an qr code.
I did add a second bankid on my old XA2 plus so i do have a backup if i something happens to my phone, do you have an older phone you can use as a backup and install bankid on it using your valid bankid or if it’s android/iOS then NFC works on it.
If you call ica banken customer service what do they advise you to do? tel:+4633474790
Edit: i did some more searching and you do need NFC with bankdosa for ica banken.
