If you have a foreign passport in Norway and rely on Bank ID for banking, beware you can get "randomly" locked out of the system, e.g. due to the scan of your passport at the bank being expired. The bank will not warn you of the issue, and just lock you out of Bank ID. Re-activating it without a Norwegian passport requires a physical visit at your bank. If that happens while you are abroad, you lose all your bank access and cannot do online payment. That means you can no longer book plane tickets, pay your bills, check your bank account. And the bank will not help you.
