Modern scientific and technological progress makes the use of information, communication, and digital technologies an attribute of any business’s functioning and people’s lives. COVID-19 pandemic, which has led to widespread quarantine restrictions, has necessitated an accelerated transition to digital remote access services. In this regard, the authors have investigated the development and spread of digital technologies in Ukraine to implement e-government policy. To assess the realities and determine the prospects of becoming a “state in a smartphone”, the authors have conducted a SWOT analysis of electronic public services. The analysis allowed to identify the advantages and threats of e-government at the present stage and outline the strategies for developing Ukrainian digitalisation. In the state as a service, digital changes are taking place in many industries and spheres, so the authors have identified key components of the digital state, including cybersecurity, e-government, smart cities, digital skills, e-court, e-health care, e-transport, and the Internet. These components are closely linked to e-democracy, e-business, and e-education. In Ukraine, there is a unique state web portal of electronic services, “Diia”, which provides access to dozens of electronic state services. Therefore, the authors have studied the purpose, features of use, opportunities, and difficulties of the portal and mobile application “Diia”. In the usage part, the authors have considered the specifics of authorisation on the portal through the file media of the digital signature and built the appropriate algorithm of actions. Along with the potential risks, modern information technologies provide many opportunities for their users. Finally, the study allowed to outline the prospects for the digitalisation of the Ukrainian state in modern realities
