The ScotAccount service is already used by a number of government services. You may already have signed up to use ScotAccount to access services such as applying for a Level 1 disclosure with Disclosure Scotland or a disclosure for the Protecting Vulnerable Groups (PVG) scheme.
ScotAccount is one account which allows you to sign into a variety of services.
It will prove your identity when using our service. This will enhance the protection already on our systems.
