+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# UniversalAuth
+This project aims to bring a variety of custom authentication options to various Android ROMs.
+
+**Your phone needs to have Xposed (or EdXposed/Lsposed).**
+
+**This project has only been tested on Android 11. It may work in Android 10 and 12 though.** Support for more Android versions is a goal and I welcome contributions!
+
+**You currently cannot use this project to authenticate in apps. It can only unlock your lockscreen.** Support for using this project to authenticate in apps is under development/investigation.
+## Authentication modules
+Currently available authentication modules:
+
+- [Face unlock](#face-unlock)
+
+### Face unlock
+Face unlock allows you to unlock your phone with your face.
+
+#### WARNING
+The face unlock module depends on closed source, proprietary libraries developed by Megvii.
+I do not have a license to distribute these libraries and **Megvii has filed
+DMCA takedown notices to take down repositories containing these modules in
+the past**.
+
+Therefore, to use the face unlock module, you will need to obtain these library files yourself.
+The module will ask you to provide these files during setup.
+
+Here are the `SHA1` hashes of the library files:
+
+```
+For arm64 phones (most phones):
+Filename: libFaceDetectCA.so          SHA1: 0e9e08c7cc976e86a8b2c80732b0f3cef3ed09be  Size (bytes): 256088

+For 32-bit ARM phones (very very old phones):
+Filename: libFaceDetectCA.so          SHA1: cc5acf3fdc29d85a59fb7b1970fc41c7120e7fa2  Size (bytes): 136888

+Filename: libMegviiUnlock-jni-1.2.so  SHA1: 44e77a1b87690d3571209a40a228e30fe185332c  Size (bytes): 136888

+
+x86_64 phones are not supported, but they are pretty rare.
+```
+
+#### Installation
+1. Install and enable the UniversalAuth Xposed module. You can download it from [the releases page](https://github.com/null-dev/UniversalAuth/releases).
+2. Reboot to make sure the Xposed module is enabled.
+3. Install the face unlock auth module APK. You can download it from [the releases page](https://github.com/null-dev/UniversalAuth/releases).
+4. A new app called "Face unlock" should now appear, open it.
+5. Add the [library files](#warning) when asked.
+6. Grant the app permission to unlock your phone when asked.
+7. Enable the accessibility service when asked.
+8. Press the "START SETUP" button to enroll your face. The app will ask you to grant it camera permissions, make sure to select "allow while using the app" if that option is available.
+9. Lock your phone and test that you are able to use face unlock!
+
