More and more email clients are now starting to support the CLIENTID extension for IMAP, including 'libetpan', SaneBox, BlueMail, and now as of Thunderbird 68.5.0, available there as well.
This allows for a form of native two factor support, permission token, and/or access control to prevent the unauthorized use of email address and password. (For more information, please see the RFC Drafts, or reach out to us off list for details)
While the version of dovecot we use has supported it for some time now, we would like to make it available for more email providers who use dovecot.
For the record, for those interested in having your dovecot support transparent multi-factor, in your implementation, you will have to compile it with the patch listed in:
https://github.com/dovecot/core/pull/86
Once that is done, please feel free to reach out to us for the dovecot plugin, that enables CLIENTID to be supported in the IMAP protocol.
