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]> 
	login response json ->  {'success': True, 'requires_twofactor': False, 'login_complete': True, 'transfer_urls': ['https://store.steampowered.com/login/transfer', 'https://help.steampowered.com/login/transfer'], 'transfer_parameters': {'steamid': 'XXXXXXXXXXXXXXX', 'token_secure': 'XXXXXXXXXXXXXXXAAD2EEF9ABFACXXXXXXXXXXXXXXX', 'auth': 'XXXXXXXXXXXXXXX4d4dc71ff713ed71XXXXXXXXXXXXXXX', 'remember_login': True, 'webcookie': 'XXXXXXXXXXXXXXX417DBA7D4A9274XXXXXXXXXXXXXXX'}}
