I recently noticed that Google Authenticator (and indeed Microsoft Authenticator) can be used with the TOTP method in Advanced Authentication to provide access to Filr
Is this what you were looking for?
regarding "... Filr does not currently support third party Multi Factor solutions.", I remember AA can forward the auth request to 3th party solutions so I guess that would work right?
Multifactor authentication for eksternal users is very big wish on our part. I know this could be a challenge according to the way Filr handles eksternal users. If anyone has a soloution to this - please send us i that direction
I recently came across a customer who was using Microsoft Azure Proxy with Multi Factor authentication to access Filr and Content Editor. So this can be done to some extent outside Filr.
There is a MultiFactor authentication entitlement with Filr Advanced. This is delivered with Advanced Authentication Limited with 4 methods (SMS OTP, Email OTP, TOTP and Radius) so this can be implemented with no additional license cost.
However Filr does not currently support third party Multi Factor solutions.
