We have several font foundries partners who allow you to license a web font from them and then use Adobe Fonts for the web font hosting. This "bring your own license" option is available from:
Once you’ve licensed a web font from the foundry, you’ll receive a link to add it to your account. Your new font will be instantly transferred to your account and will appear under your Purchased fonts.
Only fonts purchased from one of our foundry partners, listed above, can be added to your account. It is not possible to upload fonts purchased from other font foundries or resellers and host them from Adobe.
