Expired User Code on Device Authorization Flow

Help
,
1

I’m creating a command-line application using Device Authorization Flow:

Here is the sequence:

  1. Authenticate my command-line application using sample command eg. myapp --login-device-authorization-flow
  2. Command Line Application will provide login link (verification_uri with user_code)
  3. Command Line Application polls for the access_token
  4. User logs in on auth0 using provided link

Scenario:

  1. User visits verification_uri with user_code then proceed to login link
  2. User failed to log in due to some problem (eg. lost internet connection)
  3. User visits again verification_uri with user_code then proceed to login link

Result:
Invalid or expired user code.

Question:
In the above scenario, the user cannot log in using the provided login link since the user code expired while the command line application is still polling for the access_token.

Is there a way the command line application determines user code has expired?

Hi @bulatao.ramoncito,

There is an expires_in param in the response.

Does that answer your question?
