Amazon Alexa Account Linking Throws Session Timeout on redirect

Question

I'm using Amazon Security Profiles (LWA) for a new Alexa skill and following this tutorial: https://developer.amazon.com/blogs/post/Tx3CX1ETRZZ2NPC/alexa-account-linking-5-steps-to-seamlessly-link-your-alexa-skill-with-login-with-amazon

Everything seems to work well. It redirects me to the Amazon login and shows me the scope to grant access. I click allow and rather than seeing the "Your xyz Skill was successfully linked" message I see an error "Your session has timed out" with information to return to my app and log in again to continue using Login with Amazon. I expected it to go back to the Alexa app and say I was good. I have two factor enabled for my Amazon account so I thought maybe that contributed to the timeout but I asked it to not prompt me again for this device and tried again and see the same timeout error message.

Answer 1

We have identified an issue preventing Account Linking preventing to succeed when using Login With Amazon and the Android Alexa App.

Account linking succeed from a desktop browser (Chrome, Firefox, Safari) or the iOS App.

Workaround is to whitelist “na.account.amazon.com” domain in Alexa developer portal.

We will update the system to add this for you by default. I will let you know when available.

Fix is now live and this problem seems to be solved

Answer 2

The only way I could get this to work on my Android device w/ firefox as default browser -

• Open firefox, go to amazon.com and log in
• From Alexa app - find my skill- link account.. it launched firefox.. then I agreed.. and it linked.

Seems like there's a loss of something between Alexa app and Firefox so the auth breaks.

Answer 3

Exactly the same problem here. I also have 2-step authentification on. Alexa will jump to Chrome, and stuck with this error.

I use a workaround by going to alexa.amazon.com to enable the skills and have no problems. However, on my Android phones, exactly the same problem appears.
