Thanks for instructions!
I may try that. For now, my gmail is forwarding to my icloud email address.
I have to think about how to handle the interface on my Mac so I get mail on both devices.
Its complicated.
This is any difference in the data that google collects/receives when signing in using “Sign in with google” vs signing in with an app specific password?
Depending on the algorithm, the OTP token generation can include the IMEI. The IMEI itself is not transmitted.
Yes, roughly. Your IP address is registered with a regional registry, so at least the vague region is known. Some registries, especially in the US, bind IPs to exact locations in street level. - You can try using a VPN if you don’t like that, but many states require VPN providers to send a “forwarded for” header.
Device type, operating system, local time, browser/app ID and version, as well as unique OTP token generation token.
