Authenticating with BankID
For some organizations, giving end users easy access to their services is more important than being sure about the end user's identity. But for others, being 100% confident on the end user's identity is of utmost importance. Just imagine if someone else was given access to your bank account or your health records, if someone could impersonate you in context of the housing register or public services, or if someone could register for a credit loan in your name. Generally, the more sensitive a customer relationship is in nature, the more value should be placed on verifying end users' identity.
