Update: Looks like they do support some 3rd party apps. DIRECTV NOW has updated their site and now lists Disney owned apps like WatchESPN along with HBO and AMC as supported apps.
Cord Cutters News just talked with DirecTV Now and has confirmed that at launch you will be limited to the DirecTV Now app. You will not be able to log in to other apps like FXNow, Fox Sports Go, etc.
They did add that this was at launch so there is hope that later they will add additional support, but if you want unlimited data on AT&T it will only work if you use the DirecTV Now app.
We did find a mention of WatchESPN in the DIRECTV NOW help page on their site so it is possible that WatchESPN will be supported at launch or shortly thereafter. If you had hoped to use your DirecTV Now login to access TV Anywhere apps on unsupported devices like Roku, you will be out of luck.
This may not be a bad thing if they successfully bring the same on-demand content to the DIRECTV NOW app that other 3rd party TV Anywhere apps have.
Just to be clear, Cord Cutters News has confirmed this with DIRECTV NOW staff. Hopefully, the at launch comment means support for third party apps will be rolling out at a later date.
Update: DIRECTV NOW’s Twitter account posted that HBO and Disney apps will be supported recently. We contacted our DIRECTV NOW contact who repeated that 3rd party TV anywhere apps will not be supported.
We also see that they now added a new section to their help section to talk about Disney, HBO, and Freeform login. It is possible that these apps will be supported close to launch but not at launch and are working to get conformation.
