Serviio

on the serviio console and can not edite the remote tab, its grey all. I can not change the password??

It's because the password is only used for MediaBrowser, which is available in the Pro edition.

I have just bought pro version, and I still cannot set up password in the Remote tab. There is no such option.
my version is Serviio Pro 2.1

never mind, found it.
You set up user (case sensitive) and password in the Users tab, and then access mediabrowser through http://localhost:23424/mediabrowser or http://<pc5dczc_pc_ip_address>:23424/mediabrowser

Correct, starting with Serviio 2.0 user accounts now replace the remote access control function. Just a heads up for anyone that comes across this old thread.
