You can find servers wanting or welcoming players quite easily through sites such as trackyservers. My community does currently host an additional Valheim and Minecraft server on the side of our main establishment in Mount & Blade: Warband. They will be kept alive for the forseeable future, but aren't very popular/used, but anyone is really free to be on them.

We do have a password for the Valheim server, since it's not modded with additional security, unlike our MC server where we have a basic grief prevention plugin, but it's easily found on our website under servers. https://nwrp.eu
