How can I share my adobe cloud fonts to my coworker so that they can activate and use the same fonts I use?
Is there a way I can send them to her adobe account so they will be activated automatically?
Are you using Creative Cloud Libraries to store assets yet?
See Collaborate on Folders and Libraries
If you and your co-worker are not on the same Teams / Enterprise plan, s/he will need to get their own Adobe Fonts. Send them a link to the font on Adobe Fonts.
You didn't say which application(s) you are using. If you are using InDesign or Illustrator, for example, your co-worker should get a message that the typefaces are missing with a button to "Activate" which will automatically activate them on her account.
