VID stands for Virtual ID, which is a temporary, revocable 16-digit random number mapped with the Aadhaar number. It is a unique number that can be used in place of the Aadhaar number whenever authentication or verification is required. The VID is generated by the Aadhaar holder and can be used for authentication and eKYC. The VID is a second layer of security that ensures that the authentication agencies do not have access to the Aadhaar number. The VID is valid until the user generates a new one. The VID can be generated online by visiting the UIDAIs official website. The VID can be used to avail of various financial and governmental services. The VID is revocable, which reduces the chances of duplication. The VID brings several benefits for Aadhaar cardholders, including privacy protection, convenience, compliance, security, and portability.
