I have a PC tower with no attached display. I use my macbook pro to connect to it with teamviewer. This works fine. However, every so often I get the following when I try to connect. The password is invalid. As I have no monitor, it is a major hassle for me, as I have to disconnect the PC, drag it to my living room to connect it to my TV with an HDMI cable, just to get the password and then drag it back to reconnect. Any help would be greatly appreciated.
Welcome to the TeamViewer Community!
It sounds like you're using the random password option if you're having to update the password to connect regularly. If that's the case, try setting your own permanent password so that doesn't happen. You can find that by going into Extras, Options, Security, "Personal password (for unattended access)". Or, you could instead use the Easy Access feature.
Hope this helps!
