Hi Valentina, I've not tried this myself, so I cannot be sure it is a solution here, but have you tried generating a Google App Password [1] for the Gmail account to use in NiFi in place of the user password?
I'm not sure if it is a drop-in replacement or not, but worth trying to see if it works with NiFi IMAP/SMTP processors as-is. If not, we should probably capture this as an Apache NiFi Jira if it has not been already, as this is essentially a feature request to add that capability as an option/alternative form of authentication for IMAP/SMTP processors.
