The new system for online government services lost the certification administered by its own parent department, and work continues to regain the badge, in collaboration with the provider in question

The Government Digital Service team delivering GOV.UK One Login is “working closely” with a key technology supplier to help regain the system’s formal trust certification – which it lost five months ago.

Earlier this year it emerged that One Login had lost certification against the UK’s formal digital identity standards framework – which is administered by GDS parent organisation the Department for Science, Innovation and Technology.

Launched a year ago, the UK digital identity and attributes trust framework enables technology providers to obtain a government-endorsed trustmark. Certified digital ID providers can then be searched for via a publicly available online register – a list which, since May of this year, no longer includes government’s own One Login platform.

Shortly after the trustmark was removed, government indicated that One Login had lost its badge because a supplier – understood to be authentication tech specialist iProov – had “allowed their certification to lapse”. But the One Login team was already “working to commence recertification”, government added – although a timeline or process for doing so was not provided.

In answer to a recent written parliamentary question from fellow Labour MP Clive Lewis, DSIT’s digital government minister Ian Murray last week said that this work is still ongoing – and involves GDS experts collaborating with the supplier in question.

“In April 2025, GOV.UK One Login’s Trust Framework certification was suspended due to a supply chain issue where one third party allowed their certification to lapse,” he added. “We are working closely with the supplier and our Conformity Assessment Body to resolve this issue and regain certification as soon as possible.”

Several months ago PublicTechnology revealed that the end date for completing delivery of the new government-wide sign-in system has been formally pushed back by three years, with additional extra investment likely to add up to hundreds of millions of pounds. But government has insisted that the move does not constitute a delay against the previously scheduled timeline – but rather an expansion stemming from the success of the project’s implementation so far.
