Having APK access for tools like Proton Authenticator would definitely help users who prefer direct installs outside app stores. That said, security should stay the top priority, especially with authentication apps. I’ve seen discussions around how unofficial APKs or modified apps can introduce risks or misuse scenarios like those explained here https://bombituppro.com/. So if Proton ever releases APKs, strong verification and integrity checks would be essential to keep users protected.
