Incoming single government platform for enabling citizens to sign in to departmental services has seen its usage grow strongly in the past 24 months, with adoption continuing in recent weeks
The number of government services that have now implemented GOV.UK One Login has now passed 120, a minister has revealed.
The very first services to incorporate the new government-wide sign-in system did so in late 2021, initially on a trial basis. By the start of 2024, adoption had risen to only 11 services – but this figure began to rise rapidly in the following months, growing to more than 50 by the end of the year.
The volume of services enabling user access via One Login passed the 100 mark in late 2025 and, according to recent comments from digital ID minister Josh Simons, has continued to increase steadily in recent weeks.
“The GOV.UK One Login system is fully operational,” he said. “Users can set up an account, sign in and then prove their identity to access an initial set of 122 government services.”
Simons, whose role is split between the Cabinet Office and the Department for Science, Innovation and Technology, was answering a written parliamentary question from Liberal Democrat Manuela Perteghella, who asked “whether any recruitment, procurement, or system development activity has been initiated or progressed in relation to digital identity and the One Login for government programme”.
“Digital identity policy is in development, with a dedicated team inside the Cabinet Office working to develop the proposals,” the minister added. “Any notices relating to public procurement will be accessible [online].”

One Login was developed by the DSIT-based Government Digital Service; the platform is intended to replace a previous patchwork of 191 separate accounts systems and 44 differing sign-in methods used across government.
A blog post published by GDS in November indicated that about 14 million citizens have used One Login to date to sign in to a government service or to prove their identity.
The security of One Login has come under scrutiny in recent months after it emerged last summer that the system had had lost certification against the UK’s formal digital identity standards framework – which is administered by DSIT itself.
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”.
In late October digital government minister Ian Murray said that the GDS team delivering One Login was “working closely” with a key technology supplier to help regain the certification.
