sirfartsalot Can someone help me use a YubiKey with GrapheneOS? I used other posts on this forum as a guide, but I can't figure it out. I tried: Create a new profile (for a repeatable starting configuration for debugging purposes). Settings > Multiple users > Add user > OK. Then walk through new user creation. As the new user, download Google Play services and Google Services Framework. Apps > Install Google Play services and Google Services Framework. Enable storage scopes on Google Play services Settings > All Apps > Google Play services > Permissions > Photos and videos > Configure Storage Scopes > Enable Ensure NFC is enabled Settings > Connected Devices > Connection Preferences > NFC > Enable Test 2FA at demo.yubico.com/playground Open Vanadium > Go to webpage https://demo.yubico.com/playground > Create new account > Add security key > Next. At this point, I should interact with my YubiKey via NFC or by plugging it in. Instead, it shows the error message "Operation cancelled" and "There was an error in the registration procedure, please try again".
