Yes, your credit union can set up a default PIB Profile for all members. This includes things like requiring knowledge-based challenge questions to log in to Online Banking, on/off flags for individual features, and maximum transaction amounts. This is in addition to the controls you already have related to Online Banking.
Be aware that the default settings are limited to those controls that don’t require the member to make a decision. For example, features such as persistent cookies and geo-location tools must be initiated by the member using his or her actual computer. As another example, there is a feature that allows for a secondary password, called a confirmation code, to be required for certain types of transactions. Since the member needs to set up that code, that requirement won’t be part of your default, but you could still make it part of your procedure when setting up a new profile with a member. The point is that depending on what controls you want to specify as the default, you may still need to get the member involved at least by talking with a CU representative to complete certain settings.
