I would not have much problem on it, but sharing the public keys with an application and even through a smartphone camera is kind of concerning, in my opinion. I would assume all xpub scanned or copy/pasted that way to be compromised and held somewhere in a Apple/Google server.
It could be so, but I'm not sure about that. Currently, in the Trezor Suite Lite settings, I can't even find it for backing up to the cloud drive. It differs from several other wallet applications, such as Unstoppable and Phoenix, which provide a backup feature to the cloud.
But I think it must first connect the Trezor device as in the Trezor suite desktop app for safer (more private) access to the xpub.
To see the XPUB of your account in Trezor Suite, plug in your Trezor and open the Trezor Suite desktop app, -snip-
Thanks for the information.
And I think the Suite Lite not having a backup option is good, but if we are realistic on the level of mass surveillance nowadays, it is likely that the XPUB still gets extracted from the phone easily, if the software/hardware providers (apple/google) were asked to do so by some government.
Also, Even though i can see the advantages of using a phone together with a Trezor during situation where a personal computer is not available, like during a travel. I am not sure how easy it would be to find a Type-C - Micro USB cable for those who have got a model one.
I assume Type C - Type C is easier and more commercial.
