Hello everyone!
Fabric created MoPub accounts are currently able to access the MoPub dashboard via the Fabric dashboard but cannot log into MoPub directly.
A MoPub created MoPub account can also log in via the Fabric dashboard if it has the same email address as the Fabric account and is linked on the Fabric dashboard.
The team has plans to add a log-in for Fabric created MoPub accounts on our website http://app.mopub.com, but this is not yet available.
If you would like to reset your Fabric password, you can contact support@fabric.io
Let us know if you have any further questions here.
