IIUC, it is a problem of Emacs configuration to detect passphrase
prompt (so that it can ask with the minibuffer).

Do you mean that you are invoking mbsync in the shell buffer (or
something) within Emacs?  For me, it works when I use LANG=C.  When I
use LANG=ja_JP.utf8, it doesn't work (because Emacs fails to detect the
prompt).

The prompt string from GnuPG is "Enter passphrase: " in English (for the
loopback mode).

Please see the Emacs documentation for the configuration variable:

    comint-password-prompt-regexp

If needed, for your native language, ask how it can be configured,
possibly in Emacs forum.
