Hello,

I noticed that you name the Entitlements file to Entitlements.xaml 2, Please make sure that you add a new XML file named Entitlements.plist to the Platforms\iOS folder of your app project.

As you want to set securestorage, please add the keychain key like the following:

(XXX means your App ID)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "
http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>keychain-access-groups</key>
<array>
<string>$(AppIdentifierPrefix)XXX</string>
</array>
</dict>
</plist>

For more details, please refer to iOS entitlements - .NET MAUI | Microsoft Learn

and Secure storage - .NET MAUI | Microsoft Learn

Best Regards,
