Solution

To fix this issue,set "zimbraAppSpecificPasswordDuration" for one mintue.

Run as Zimbra user:

 $ zmprov ma user@domain.com zimbraAppSpecificPasswordDuration 1m
 $ zmprov fc -a all

Above attribute will expire AppSpecific password after one minute. The default value of this attribute is 0(never expired).

Note: zimbraAppSpecificPassword should remove once disabled the Zimbra two-factor authentication but in this case the password not removed. You can't remove or reset this password because it's saved in encrypted format in LDAP. Only way to set password expiry duration.

 $zmprov desc -a zimbraAppSpecificPasswordDuration
zimbraAppSpecificPasswordDuration
    lifetime of app-specific passwords, or 0 for no expiry. Must be in
    valid duration format: {digits}{time-unit}. digits: 0-9, time-unit:
    [hmsd]|ms. h - hours, m - minutes, s - seconds, d - days, ms -
    milliseconds. If time unit is not specified, the default is
    s(seconds).
