AT&T Uverse App on Firestick login

@customerservice HELP!

The Wi-Fi login would be useless. 

Unless you have created an Access ID where you have merged accounts, then the correct login would likely be the one you use to pay your bill.

Keep in mind that this isn't a direct channel to AT&T Customer Service, and you shouldn't expect rapid answers from anyone, and especially from anyone employed by AT&T.  This is primarily a place where customers assist other customers.

Thank you @JefferMC I appreciate your help! We were told by an AT&T Tech that AT&T is phasing out the cable boxes & that everyone will eventually have to use their streaming service through AT&T/DirectTV. Just trying to get hip with the new ways since the cable box service isn't always the greatest, & since AT&T isn't providing support for them anymore... We have 1 family member not ready or interested in using the U-verse streaming app, but we'd like to show him the guide & app interface.. I'm sure it's similar, maybe even better than, to what is available in the old clunky cable boxes .. lol.

Thanks a bunch!! 

Yes, AT&T is, at some point, going to do away with U-verse TV.  No one knows when.  Yes, they push DIRECTV STEAM as a replacement.  Yes, I do think that this new version of the AT&T U-verse TV app is intended to get you that much more comfortable with the DIRECTV STREAM product.

The app is really nice on phones, where you can decide to record something while away from home and or watch something when you're waiting somewhere.  If you want to save $10/month on a set top, it might be worth trying out, but remember you'll have no access to actually playing back an actual U-verse TV recording.  You can start and schedule (and even delete) recordings, but you will not be able to watch them from this app.  You can watch programming on the "live" channels and any on demand content you can get to, but this will not include your local channels, at least not so far.

I am having the same problem. I tried rebooting the whole system and also changing my password. Nothing has worked. On the fireTV I am able to download the APP, but once I try to open it I get an error message.  Please help! 

It's weird because I talked with an AT&T customer via my customer service job (completely not related to AT&T) who didn't have an Amazon Firestick or Firecube & who didn't access the app in her phone or tablet or the service through her computer... She had a smart tv and her son downloaded the apo and it worked just fine, recorded stuff and accessed in demand and live tv, the only catch, she had to download the DirectTv/Uverse App .. 

I guess for this household we'll be waiting until we have no choice lol

So I do believe you have to use your AT&T account username & password to login to use, not the wifi username & password. 

I tried loading the direct tv app and it may have worked, but I was asked to pay 79.99 a month.  I am already paying for Uverse and I can't use it!  I did use the att username and password, but nothing has worked.  Any other ideas?  I am now considering just calling for tech help over the phone, but I am afraid that will be an exercise in frustration.

The DIRECT TV app is for a different service, not U-verse TV. There are similarities between the apps but you need the app that corresponds to the service you pay for.  The U-verse app doesn't work on FireTV devices released more than about 5 years ago, and tablet support seems to also have gone missing.
