I already reset it on the server side to something besides "smate".
But if I click on the eyeball icon in the browser app, it tries to connect to vnc using the default password, and I never get a chance to enter credentials.
Same issue I have been having. I followed the instructions on SM's FAQ page, and I can use RealVNC or the Mac screen sharing app and connect and use the new VNC password.
But if you try to use the web interface to the RPi or the IOS app (in my case) you get an authentication error and there is no prompt for the new password. It's like the default is hard coded or there is something that is not being passed to OpenVNC to prompt for a password if authentication fails (or prompt when trying to connect). My ticket over there is still open. I was starting to think it was just me having the issue.
A bit late but whatever. The reason is that the password is baked into ekoslive. You can open that frame in a new tab, then edit the url to reflect your password and create a bookmark with it.
