Connecting your comiXology and Marvel accounts is easy!
All you need to do is head over to https://www.comixology.com/my-account/marvel-sync. From there you can follow the steps in order to log into both accounts. Once you sync them together, your Marvel account library will appear inside of your comiXology account and the Marvel books you purchased while on comiXology will appear inside of the Marvel app. Future purchases will automatically show in both apps.
If you have any questions about this process, please reach out to our customer service team!
