The new login service has two factor authentication and will be rolled out across all government web services to replace Government Gateway accounts over the next three years.

The project is being led by the Cabinet Office with HMRC one of the first government departments planning to roll out the service.

In future, users will only need a single login to access all central government services, rather than remembering multiple accounts and passwords. Gradually, over time, One Login will replace all existing login and identity checking platforms across central government. Government Gateway is over 20 years old and was first introduced in January 2001.
