The persistent notification requesting authentication for a Wi-Fi network on Android devices typically arises when the device detects a network requiring a login through a captive portal. This portal often presents terms of service, requests personal information, or requires payment before granting internet access. A common example is encountering this prompt at a hotel, airport, or public coffee shop Wi-Fi network.
This repeated sign-in request mechanism ensures device security and prevents unauthorized access to the network. It safeguards the user by making them aware of the specific terms and conditions associated with the network before establishing a connection. Historically, this functionality was introduced to adapt to the growing prevalence of publicly accessible Wi-Fi hotspots requiring authentication methods beyond a simple password.
