Steam login/dologin "steamLoginSecure" a way to get it?

[Alin Tabuci]

Hi! Recently i started working on a process that would change multiple accounts store country, or other settings (if it's even possible), using:

POST /account/setcountry

So i checked the requests (in the devtool) that steam does in the background, and found out that with each request they send session id and in the cookies they send a field called "steamLoginSecure", i took that request and started removing fields one by one to see what fiield are required and eventually figured out that sessionid field is required but for some reason it's value is not important (maybe i didn't understand it right), but "steamLoginSecure" is required and it's value must be correct so i started reading on the internet about this field, and got to the point where everyone says that it's very important, it's used for generating .maFile and it's more important than the password of an account. 

Well in order to make those requests work automatically i need to get "steamLoginSecure " somehow.

I'm doing my authentication through 

https://steamcommunity.com/login/getrsakey/

then

https://steamcommunity.com/login/dologin/

So the question how do i get it? Is it even possible?

I hope i explained everything correctly, it's my first time asking a question on the internet! Thank you!

 

 

P.S: I'm doing it in php, and i do have the maFile of those accounts.

You can update your Steam country setting when you complete your first purchase using a payment method from that country.

Automating the steam store is against Steams terms of service

Okay but what about "steamLoginSecure", is there a way of fetching it? I mean there are other endpints that i'd like to use that are not connected to the store anyhow.

1. https://steamcommunity.com/login/getrsakey/?username=
2. encode pass to base64 rsa encrypt with mod and exp from getrsakey
3. and use in body of POST https://steamcommunity.com/login/dologin/
4. process dologin by response like success, requires_twofactor, emailauth_needed

Thank you for the response!

 

I did already authenticate, i just cannot really understand where do i get the value of the field on the screenshot, because steam does check for its value in otherwise the response is "null"

 

In authentication response there's no such field, or maybe there is but i have to encrypt it or something..

I Totally get cookie when i use credentials using oauth authentication.

1. https://steamcommunity.com/login/getrsakey/?username=
2. encode pass to base64 rsa encrypt with mod and exp from getrsakey
3. and use in body of POST https://steamcommunity.com/login/dologin/
4. process dologin by response like success, requires_twofactor, emailauth_needed
After dologin response was cookies then it tokens occur there.

login response ->  <Response [200]>
