You mustn&#x27;t use your &quot;onymous&quot; Google ID on this burner phone, nor have any contact between your pseudonymous Google ID and your public Google ID. I guess the guide should spell this out more, I took it as implied when the guide started by buying a non-trackable phone with cash.<p>Edit: quote from the guide: &quot;11. Only use this device for Signal (and maybe Google Authenticator, see #13) from now on to minimize its exposure.&quot;
