2FA for Business

Marco.heinemann@useblocks.com shared this idea 13 months ago


it looks like mailbox.org does not support 2FA / MFA for business. At least there are no options in setup.mailbox.org or in the user mailbox settings.

If that's true, when will this be available? It's pretty much a deciding factor for me.

In that regard, it would also be quite relevant to support app specific passwords for caldav/carddav/imap clients.

Thanks, Marco

Thank you very much for your inquiry. The integration of 2FA for our private customers has been an integral part of our services for several years.

Since additional security is equally vital for our business customers, we are going a step further and would like to make use of the latest technologies and additional layers of security in the near future.

Your mailbox.org team

We are already working on this feature. Unfortunately I can't give you a fixed date for the implementation as of right now.


Are you working on 2FA AND app specific passwords as mentioned what Marco asks.

Or do you only mean 2FA? Really looking forward to app-specific passwords within mailbox.org


For Two-Factor authentication (2FA) for Mailbox.org Business, for Mailbox.org review, and decision, I suggest considering those three:
--- --- --- --- --- --- --- --- --- --- --- --- --- --- --- ---

Below is the same suggestion as above. But with details if you're interested in those.

All 3 products listed above have strong security and strong privacy. Because they are open source :) My favorite is LemonLDAP-NG. Because, legally speaking, LemonLDAP-NG is owned and controlled by both you and a not-for-profit community. In comparison, Keycloak is, legally speaking, indirectly owned and controlled by the for-profit IBM. Shibboleth is my second favorite.

If needed, both me and the Ubertus.org team would be happy to contribute testing and documentation for 2FA. Whatever which option Mailbox.org chooses.

Below is the same message as above. But with details if you're interested in those.

They do not have an estimated time of delivery (ETA)

For those not familiar with Keycloak, it is "an open source software product to allow single sign-on with identity and access management aimed at modern applications and services."
