[Bug]: App doesn't show CAPTCHA that may be required for log in

[sivaraam]

Summary

In some cases, a CAPTCHA might need to be solved by the user in order to successfully log in. This may be necessary due to some number of failed login attempts. The app is not able to identify such scenarios and properly show a CAPTCHA to the user. Instead, the login fails.

This was first reported here: [reference]

Steps to reproduce

Steps given by @OpenGreenStreet:

1. The app requires a new password to be entered due to a previous password change (up to this point completely normal).
2. Immediately before the new password was entered in the app, there were several unsuccessful password entries (e.g. due to an "attack" on the account by a third party).
3. The app does not recognize this captcha/cannot display it. Entering the correct password also fails in the app.

Expected behaviour

The app should show the CAPTCHA and allow the user to enter the same and successfully complete the login similar to the web interface.

Alternatively, the app could imitate what the Wikipedia app does. It seems to show a toast asking the users to wait for 5 minutes before trying further login attempts. Note that the app properly shows this when the login attempt fails 5 times within the app. We need to check what happens when the same happens in web and user logs into the app right after that.

Actual behaviour

The app fails to show the CATPCHA. So, user is not able to login.

@sivaraam @nicolas-raoul As discussed in the original Issue discussion I will be working on this issue

[sivaraam]

@shashankiitbhu Could you clarify how you plan on addressing this issue?

[shashankiitbhu]

@sivaraam Sorry for the late reply, I was out of the station, and I was thinking of a way to actually show CAPTCHA within the app ? I don't think we have any end-points for that as of now ?

What we can do is to redirect the user to WebView where they can log in? (In this specific case only)

Yeah. I'm not aware of any endpoints either. Could you check regarding this in the wikitech-l mailing list on what could be done in this situation?

For this, I suppose we would need to explore the feasibility of getting the auth token post a web login.

Before that, could you check how the Wikipedia app handles this case?

@sivaraam The Wikipedia app displays the CAPTCHA in the app itself.

I started a thread on Wikitech-I regarding this, yet to receive a response.

I tried to view the CAPTCHA bit couldn't do so. Could you possibly share a screenshot of this screen for reference? Specifically it would be helpful to know in which case you were able to see the CAPTCHA in the app.

Nice. Let's wsee what we get. Given the Wikipedia app is able to show the CAPTCHA, it would worth checking out their code to know how what APs they've used.

@sivaraam I observed that Wikipedia app is capable of showing CAPTCHA for login in the app itself

[sivaraam]

That seems like the CAPTCHA from the "Create account" page. We're actually concerned about the CAPTCHA that needs to be shown upon login. We don't need to worry about it since we redirect to the web page for the "Sign up".

Could you check how the login case is handled by the Wikipedia app?
