Get Access_Token with Steam User

[SteamUs1]

I understand that the access token is highly sensitive account information. However, the Steam WebAPI at https://api.steampowered.com/IEconService/GetTradeHistory/v1/ currently requires the access token for functionality.

My question is: Do I need to use Steam-Session to obtain the access token, or is it possible to retrieve it using Steam-User?

Thank you for your assistance!

I don't know if you can get an access token directly with node-steam-user, but you can at least listen to 'webSession' event, get cookies and find steamLoginSecure there. steamLoginSecure actually contains access token, so you can extract it. Format of steamLoginSecure is `steamId + "%7C%7C" + accessToken`

Okay, that would be very practical! 
I'll try it out straight away, that would solve the problem directly, as I always use cookies anyway. Thank you!
