>What would happen if one either loses his Trezor or get it stolen, regarding 2FA on say google accounts, dropbox, github and the like? Would it be possible to login into these websites, if so, how? I guess that owning another Trezor and knowing the seedphrase would do it, but would there be other ways?
You could get another Trezor and restore your seed phrase and then use the u2f again. Or, you could use the individual website’s backup method to login (like a backup code, or sms fallback, or whatever the individual website uses for that situation)

>How do you deal with 2FA with Trezor with an Android phone? I am considering to use 2FA on all websites allowing it, but I don’t know how this would impact my Android phone (e.g. my google account). The Trezor cable is usb-c to usb 2.0, i.e. does not fit into a phone without an adapter.
You would need to get the appropriate cable or adapter.
