H.R. 7704 requires the Department of Veterans Affairs to use multi-factor authentication when processing high-impact requests through its call centers. High-impact actions are defined as those where an impersonator could cause serious, lasting harm to veterans or beneficiaries—such as diverting funds, manipulating account access, or exposing sensitive information. The bill amends existing law to mandate these additional security controls to verify that callers are who they claim to be before the VA completes such actions. The legislation does not specify funding amounts or implementation deadlines, leaving those details to the VA's discretion as it updates its call center procedures.
