Passwordless auth issue on Android

Hi! I’m using Auth0.Android 1.13.0 to setup passwordless authentication in my native app. I’m following this guide: Lock.Android: Passwordless

I was able to send out the email with the code, however i’m unable to sign in, i got the following error on my log:

07-12 22:35:15.734 10348-10639/io.nold.keychain D/OkHttp: --> POST HTTP/1.1

I’m guessing its because the /ro endpoint is deprecated and it should be oauth/token instead?


Hi @viszt,

I’m sorry for the delay in response on this. I am going to post the solution for the sake of posterity.

The endpoint is in fact deprecated as you mentioned, and should be the cause of the error.

The current endpoints can be found here:
