Gov.UK Verify, the new Electronic Identity Management
(eIDM) system of the UK Government, has been promoted
as a state-of-the-art privacy-preserving system, tailored to
meet the requirements of UK citizens and is the first eIDM
in which the government delegates the provision of identity
to competing third parties. According to the recently
enacted EU eIDAS Regulation, Member States can allow
their citizens to transact with foreign services by notifying
their national eID scheme. Once a scheme is notified, all
other Member States are obligated to incorporate it into
their electronic identication procedures. This article examines
Gov.UK Verify's compliance with the requirements set
forth by the Regulation and the impact on privacy and data
protection. It then explores potential interoperability issues
with other national eID schemes, using the German nPA,
an eIDM based on national identity cards, as a reference
point. It concludes with a general overview of legal equivalence
of third country legal frameworks compared with that
of eIDAS. The article contributes to relevant literature of
privacy-preserving eID management by offering policy and
technical recommendations for compliance with the new Regulation
and an evaluation of interoperability under eIDAS
between systems of different architecture. It is also, to our
knowledge, the first exploration of the future of eID management
in the UK after a potential exit from the European
