Hello Sarfaraz, I’m the author of the Central Auth plugin. Are you using the plugin to authenticate against an LDAP or CAS server? Our University’s central IT manages MFA for all accounts through the campus CAS server, and I am currently working with a developer from another university that has MFA enabled for their LDAP server. Is there any possibility your security officer can enable MFA for your single sign-on method?
I’m not aware of any plugin that adds MFA directly to Omeka, though I think it would be possible to code your own.
