I got this response from Twilio support
Our latest version of the Authy application includes important security improvements designed to protect your data and strengthen the protection of your tokens. According to the details you've provided, your device may not comply with the minimum requirements to run Authy; please follow the suggestions below and try registering it again:
- Verify your Android version: Ensure you're using an official version of Android provided and maintained by your device manufacturer. Third party distributions are not supported.
- Confirm your device is not rooted: If your device has been unlocked or rooted, unfortunately, you will not be able to use Authy.
- Update the Google Play Store: Make sure you have the latest version of Google Play Store. Follow the instructions in How to Update the Play Store & Apps on Android to keep it up to date.
- Download Authy from the official Google Play Store: Only download the official Authy application from the Google Play Store. APKs from third-party sources may not function properly.
- Ensure you have the latest version of Google Play Services: Verify that Google Play Services is installed and updated on your device. Refer to Keep your device & apps working with Google Play Services for more information.
If the error persists, we kindly ask you to wait 12 hours before attempting to register Authy once more, and share your device details, like manufacturer and software version with us.
Keep in mind that we no longer support Authy Desktop, if you're trying to register Authy on a Desktop device, please use an Android or iOS device to do so.
Additionally, after checking the specifications of the phone that can be found in the web portal [link to Unplugged's website removed by moderator], unfortunately the phone is not supported to use Authy. If you check the following article, you are going to see that the supported operative systems we have for Authy are Android and IOS.
I said in my ticket that I was using a Pixel with GrapheneOS, an OS modified from Android. I gave all the information they asked for in the initial ticket. I also linked to the attestation guide. I don't even know where they got Unplugged from.
I'm going to respond that I meet all their requirements besides alternative OS and following the attestation guide will allow them to support GrapheneOS.
