Two Factor Authentication - Adds an additional more secure method of authentication for users through the use of 2FA codes. The feature is configurable by domain and allows the ability to enforce its usage for users of the domain.
Added application passwords for KOFF, IMAP, and similar - As a supplement to the new 2FA authentication, Kerio Connect now allows specific application-specific passwords for use with other mail clients beyond Kerio Connect Client (Webmail or Desktop).
Added TLS options in GUI - Previously available only within the mailserver.cfg, the option to define a minimal supported TLS protocol is now available directly within the Webadmin GUI.
Integration with Let's Encrypt with auto-renewal functionality - Leveraging the free Let's Encrypt SSL certificates, Mail Server administrators can now set up auto-renewing certificates directly within the Webadmin's SSL Certificates section.
