Unable to authenticate

[emadde]

Thanks for the help.

I have tried many times to set/ export the variables (AMZNFLEXUSERNAME & AMZNFLEXPWD), but it is giving me the following:

"Unable to authenticate to Amazon Flex. Please provide a valid Amazon Flex username and password."

Is the app still working?

Following. I have the same issue.

Me too

I have the same issue as well

After more digging I found that
https://api.amazon.com/auth/register returns a challenge -that should be viewed on web- something like a captcha!

But, unfortunately I have no experience with how to deal with or bypass them

Start Charles proxy and sign out of amazon flex and then sign in back. In the Charles you will see api.amazon link, remember to enable SSL. Then copy your device serial number and frc from Charles and paste it into the script. And you are good to go.

This is good info. Would you happen to know what the FRC string is for? And does it change between sessions?

I don’t know. But I tested it on several peoples account who were getting error to connect and this trick worked for all of them. Get Outlook for iOS<https://aka.ms/o0ukef>

Did you setup any delay between each offer fetch request? Doesn’t Amazon flag you if you make too many requests too fast?

Here you can read about encrypting and decrypting the frc cookie. And here is a gist how it works in production.

@mkb79 Thanks for your insight here on the FRC key. Do you know if there is a way to generate the FRC without the user having to sign in to Amazon Flex on their device ?

[mkb79]

@mdesilva
For sure. Read this example for Goodreads. It works very similar to Amazon Flex device registration. Compare it with your code here.

No need to waste time with the FRC. Amazn doesn't require it anymore. Better find out what the best way not to get rate limited is instead.

@figamore
The frc cookie is needed if you want to add (register) a new device without to signin separately.

I understand that, but specifically for Amazon Flex this is not needed.
