Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government how many instances of production environment access to the One Login system were recorded in each month since July 2022; and, for each month, how many of those instances involved individuals who did not hold full Security Check clearance at the time of access.

GOV.UK One Login takes the security clearance and audit of personnel very seriously. Access to production is granted only to those that require it and is closely monitored. As part of strengthening our approach to privileged access management, all individuals with production access to GOV.UK One Login must undergo a Security Check (SC), alongside further two-person checks for changes and audit loggings of actions. One Login has implemented a policy of SC clearance for all development staff; this is higher than Baselines Personnel Security Standard (BPSS) which is considered sufficient across many parts of government.
