Mobiililähestymistunniste (Mobile Identifier) refers to a unique code assigned to a mobile device, typically for advertising or tracking purposes. These identifiers allow advertisers and analytics companies to track user behavior across different apps and websites without collecting personally identifiable information. The specific type of identifier can vary depending on the operating system. For iOS devices, this is often referred to as the Identifier for Advertisers (IDFA), while for Android, it is known as the Google Advertising ID (GAID).

These identifiers are designed to be resettable by the user, offering a degree of privacy control. Users can typically reset their advertising identifier in their device's settings, which effectively clears their tracking history associated with that identifier and assigns a new one. This process helps to mitigate long-term profiling by advertisers. The use of mobile identifiers has been a subject of debate regarding user privacy, leading to changes in how these identifiers are accessed and used by app developers and advertisers, particularly with updates to mobile operating system privacy policies. The goal is to balance the benefits of targeted advertising and app analytics with the need to protect user privacy.
