The quick and dirty:
Is there any reason not to use one long lived token for multiple devices?
Additional information that may help provide a useful answer:
I have a group of 5 computers that my players use for my D&D campaign locally at my home. Those computers all have HASS agent on them for various things. Can they just all use the same token?
What about any other devices that may use them? Any reason not to just give them all the same token?
