confirmation request does not appear on my Smartphone [..]
Essentially i can not confirm my identity to google
the device profile spoofing itself isn’t an issue, but you need to enable “Google Prompt” 2-step-verification until it’s enabled by default in /e/OS v3.3 and up, see this thread: Confused About Google Prompt (login) and /e/OS - #9 by tcecyk
(for where and why it’s spoofed to Pixel 2, same thread)
