GOV.UK ID Check is an official app provided by the UK government to help individuals securely prove their identity online. It’s primarily used as part of the process to set up or access a GOV.UK One Login, which lets you use a single login for various government services. The app uses advanced facial recognition and ID scanning technology to match your face with your official photo ID, such as a passport or driving licence. This eliminates the need to post documents or attend in-person appointments. Designed with user privacy and security in mind, your data is encrypted and only used for identity verification. It’s a quick, convenient, and reliable way to confirm who you are when using digital government services.
