clientlogin + 2FA #260

framawiki · 2017-11-11T19:24:54Z

To be able to login with 2FA enabled, we need to use clientlogin instead of login, and at least to correctly detect users with this security enabled.
In case of 2fa, a second http request is needed to send user, pass, totp (2fa code), fake loginreturnurl, rememberMe boolean and our classical token.

It's the first commit, currently the login form works as usual for normal users. users with 2fa enabled can' t be connected yet.

So this commit is not ready to be merged for now.

@benapetr I still have two main problems. Can you help me solve them? Thanks !

+            ApiQueryResult *result = query->GetApiQueryResult();
+            ApiQueryResultNode *ln = result->GetNode("clientlogin");


We need to execute this second request, but I can't finish it correctly without spending it with other connection requests.

+        // Need a user interaction like captacha or 2FA
+        //QString v_id = ln->ChildNodes.at(0)->GetAttribute("id", "unknown");
+        //if (v_id == "TOTPAuthenticationRequest"){


I can't parse the xml tree to get back the TOTPAuthenticationRequest value... Here is what contain the answer.

Isn't action=login deprecated anyway? I think we need to replace it with "clientlogin" at some point anyway or is that one also deprecated?

benapetr · 2017-11-11T21:09:07Z

Can you maybe create some diagram of how is this supposed to work? It's hard to review the code if I have no clue on how 2FA login is working within MW. Why is there even a need for callback URL, this isn't OAuth.

Are you sure that Bot login can use "ClientLogin"?

... no, i can't log me in with botpassword... so it looks like that we need to leave both connection methods available in parallel :(
@addshore can you confirm that ClientLogin doesn't support botpassword ?

I actually think that classic login was deprecated for everything except for bot passwords, basically in future it should replace classic login with bot password login only.

Why is loginreturnurl needed at all here

yeah I'll use logincontinue

framawiki · 2017-11-12T18:05:18Z

action=login looks depreciated, see https://www.mediawiki.org/w/api.php?action=help&modules=login :

This action should only be used in combination with Special:BotPasswords; use for main-account login is deprecated and may fail without warning. To safely log in to the main account, use action=clientlogin.

Please look https://www.mediawiki.org/w/api.php?action=help&modules=clientlogin too.

I think you forgot to renamed it elsewhere because now it doesn't compile at all

This is how I imagine it should work, but it now doesn't:
