Note that this subforum is generally for the single bay My Cloud units. The EX2 has it’s own specific subforum:

That said for the single bay My Cloud units there is no official way to access one’s content remotely other than using the WD My Cloud Desktop program, the WD mobile apps for iOS and Android, the MyCloud.com web portal, or using the insecure FTP method. Or one could setup a VPN (or something similar) on their local network to access the their My Cloud.
Unofficially, and not supported by WD, for the single bay My Cloud units there are several other options for remote access including SSH/SFTP, and for the older generation v4.x single bay My Cloud users there is the CloudDAVMod which allows for limited remote access (primarily remote drive mapping).
