Technical documentation
Our technical documentation will help you:
- understand how GOV.UK One Login works
- integrate with GOV.UK One Login’s test environment for authentication
The documentation covers both the authentication and identity checking parts of GOV.UK One Login.
Only the authentication part is available to all central government services now.
We’ve included information about identity checks because this feature is being tested by selected services. It will also let all services see how our identity checks work.
