To adapt to the change, you may need to set 'epa-pinentry-mode' to the
symbol 'loopback'.
Note that previously, it was said that passphrase input through
minibuffer would be much less secure than other graphical pinentry
programs. However, these days the difference is insignificant: the
'read-password' function sufficiently protects input from leakage to
message logs. Emacs still doesn't use secure memory to protect
passphrases, but it was also removed from other pinentry programs as
the attack is unrealistic on modern computer systems which don't
utilize swap memory usually.
