Shortly, our internal security team asked us to move our svn server, exposed on the internet at the moment, behind a firewall that require a two-factor authentication: user and password, as usual, plus a 10-digit numeric pin that changes every 60 seconds.
Our change request for tortoisesvn concerns the possibility of inserting the third field, besides user and password, which allows us to "trepass" the 2FA of the firewall, and, obviously, disable credential saving.
Obviously we must also implement somethig that permit to tortoise to "dialogue" with the firewall to make it accept the user / password / 2FA values. FYI our firewall is a Fortigate.
