In order to provide additional security and a smoother user experience, we have simplified the signing process. In the case of envelopes where users are required to authenticate and then sign with the same BankID method, the SSN - social security number - will be automatically prefilled and unchangeable. 

In all the other cases (such as authenticating with one BankID and signing with another) nothing will be different, and users will have to enter their SSN during signing.
