I recently switched to some local internet provider who is relatively a fresh boy in town. It is a wireless setup, with wifi antenna attached to a router in home. This is a fritzbox kid.
I observed remote access is configured for it. There were 2 users , one named "ftpuser" and another "TR069-" followed by some random string I don't recall. I removed this user but I'm not sure if is a big deal.
The router reported TR-069 service enabled but the port used is different than the one for internet remote access from which those two users benefited. Anyone has any idea of what use was the user I removed? Also just in case can I recover the credentials somehow? Many thanks.
