How to recover login datas from another application
I am making a dynamic form in witch user will enter personal datas. If he isn't connected yet (in another appli) he types his login and password in the form and he is identified thanks to a web service. But if he is using another appli yet, I would like to recover his login and password from this appli.
How can I do that please ?
Thank you for your help and sorry for my bad english
