One possibility is via the Magento Admin:

Admin -> Stores -> Configuration -> Design -> Footer -> Miscellaneous HTML

Another option via the Magento Admin is to use a widget to include a static block:

Admin -> Content -> Widget: CMS Static Block
  Layout Updates: 
     Display on: All Pages
     Container: Page Bottom

If creating/customizing a theme then you could consider using layout XML to include a template or static block.
