Authnkey is a credential provider that lets you use FIDO2 security keys (like YubiKey, SoloKey, Nitrokey, or Token2) for passkey authentication on Android. Android's built-in WebAuthn support has a significant gap: it does not support CTAP2 over NFC. This means you cannot use PIN-protected passkeys or discoverable credentials with NFC security keys — you're limited to basic U2F tap-to-authenticate. Authnkey fills this gap by implementing the full CTAP2 protocol. The app registers as a credential provider, so any app or browser that supports the Android Credential Manager API will offer Authnkey as an option when passkeys are requested. This also works on devices without Google Play Services, since Authnkey implements the CTAP2 protocol directly rather than relying on Google's FIDO2 API. Supported features: - Passkey creation and authentication - PIN verification - Discoverable credentials - Multiple accounts per site - NFC and USB transports No root required.

Auto Auto-Rotate is an extremely simple app that stores Android's auto-rotate setting per app. Do you usually disable auto-rotate and enabled it only for some apps? Like your gallery, or your video app? Do you tend to forget to turn it off afterwards? Does it bother you? Then Auto Auto-Rotate is the perfect app for you! Auto Auto-Rotate is open source and released under the GPLv3 license[1]. Check out the code if you like[2]. Required Android Permissions ▸ WRITE_SETTINGS to turn Android's auto-rotate on and off. ▸ BIND_ACCESSIBILITY_SERVICE to detect app launches. ▸ REQUEST_IGNORE_BATTERY_OPTIMIZATIONS to make sure it keeps running in the background. ▸ RECEIVE_BOOT_COMPLETED to automatically startup on boot if activated. ▸ PACKAGE_USAGE_STATS to get the currently running app. Get it You can download it for free in F-Droid[3] Translations Translations are always welcome! :) The app is available for translation as two projects on Transifex[4] [1] https://www.gnu.org/licenses/gpl-3.0.en.html [2] https://gitlab.com/juanitobananas/auto-auto-rotate [3] https://f-droid.org/packages/com.jarsilio.android.autoautorotate/ [4] https://www.transifex.com/juanitobananas/auto-auto-rotate and https://www.transifex.com/juanitobananas/libcommon

Auto Light: Precision Brightness ControlAuto Light is a specialized replacement for the standard Android adaptive brightness feature. Designed for users who demand absolute control, this app provides a custom-tailored brightness curve based on your specific environment.This is a power-user tool that may require additionally manual configuration to function effectively.For a proper function, it requires to disable the built-in Android Adaptive Brightness feature manually before using Auto Light app.How It WorksThe app utilizes a four-point non-linear mapping model to create a smooth brightness curve. If the predefined settings do not meet your requirements, it allows you to set intermediate points for four distinct ambient light levels and their corresponding intensities. The app then calculates the optimal intermediate values to ensure a smooth, predictable transition.The main intended working mode is “On screen unlock/rotate” where the app captures ambient light data only during specific triggers (like unlocking or rotating). This sets your brightness once, preventing the “flickering” or “hunting” common with standard auto-brightness.The Auto Light app utilizes Android’s notification system to ensure stable background performance. Since the app does not send active alerts or messages, you may choose to disable notifications in your Android system settings without affecting core functionality. To do this within the app, tap the three dots in the top-right corner, go to Settings, and ensure Notifications is toggled off.Permissions & PrivacyTo provide reliable system control without compromising privacy, Auto Light uses:Modify System Settings: Necessary to adjust the display brightness levels.Notifications (Service Persistence): Used to maintain a Foreground Service, ensuring the Android system does not terminate the app while it's monitoring light levels.Run at Startup: Ensures your custom brightness profile is active immediately after a device reboot.User Present & Configuration Change: Used strictly to trigger brightness adjustments when you unlock your phone or rotate the screen (No privacy-sensitive data is accessed).Note: This app does NOT require Internet access, Location data, or Phone/Call logs, making it a privacy-respecting utility.

Auto Off BluetoothAuto Off Bluetooth is a lightweight utility for Android designed to preserve battery life and increase device security. The app monitors your Bluetooth connection status and automatically turns off the Bluetooth radio after 20 seconds if no devices are connected.How it worksThe app listens for Bluetooth state changes in the stack and for Asynchronous Connection-Less disconnection events in the background. When a device disconnects, the app starts a timer. If the timer expires without a reconnection, the app automatically disables the Bluetooth adapter to save power. If a Bluetooth device reconnects, the app postpones the Auto Off task until the next disconnect.PermissionsThe app requires the following permissions to manage your Bluetooth hardware:BLUETOOTH: Allows the app to see the status of connections.BLUETOOTH_ADMIN: Allows the app to toggle the Bluetooth radio on/off.BLUETOOTH_CONNECT: To interact with paired devices (required for Android 12+).

Android app for automatic screen brightness adjustment. Replacement for built-in feature. WARNING: This app is not one click solution! It requires some configuration to work properly. It uses 4 pairs of light sensor data and corresponding screen brightness. In-between values calculated as simple linear interpolation of those points. Main intended working mode is "Screen unlock/rotate" - read ambient light data, set brightness once... and do not annoy with backlight beaming anymore. Permissions: - Modify system settings - required to control display brightness - Phone - keep reading light sensor data while phone ringing in pocket - Notifications - to prevent being killed by system - Request ignore battery optimizations - to prevent service suspend - Run background service - it has "special use" type because does not fit in any category - Run at startup - ...
