Dear Everybody:
May I ask how to configure dovecot otp one-time verification login,
that is, after the user logs in to the mailbox with the password + otp, he can
send and receive emails without entering the password + otp again?
# This is my settings:
# /etc/dovecot/conf.d/10-auth.conf
disable_plaintext_auth = yes
auth_cache_size = 10M
auth_failure_delay = 5 secs
auth_ssl_username_from_cert = yes
auth_mechanisms = otp
!include auth-ldap.conf.ext

-------------------------------
if option:
auth_mechanisms = plain login
Can send and receive emails successfully, but when the otp time expires, you
need to re-enter the password + otp, which is unacceptable to the user
Looking forward to your reply, Tanks
