You need a Bank ID to sign agreements and contracts digitally. You may have had a Bank ID on your mobile phone or disposable code in the past or maybe you still use it?
Then it may be that something has changed or simply does not work anymore. Most banks have switched to the new Bank ID app, but if you have a Bank ID from Sparebank 1 or Nordea, you must continue to use the bank's own app.
If you have questions about Bank ID, you can read more on the Bank ID website - frequently asked questions.
