Question

Hi,

 

I have Login.aspx form

 

1. UserId & Password (TextBox controls)

2. Login button (button control)

 

On Login Postback occured and everyting works as expected. But when I see request (using filddler) i can see user name and password as plain text as below.

 

What I can do for this.

 

__EVENTTARGET=btnLogin&__EVENTARGUMENT=&__VIEWSTATE=3HVAo0xXDxbiJPSckha9wY%2FvmVfvAv1xRSy36Chwv5RB%2BlVcgYWXgtwNauNazToXGCrMcs4%2BvhKazUyUQm2Yz7k8ICNinpm%2FL0H1dOP67fs%3D&__VIEWSTATEGENERATOR=1806D926&__VIEWSTATEENCRYPTED=&__EVENTVALIDATION=uezsZj9YVD2GdMVij2ggZ3GAkisLo%2BeNjmffPGdt9DfiJ4jypLJCkwUH8Gp8%2FgDmQHCiB5GpJ%2B2J5htcQ%2BUY9c2jUT9Ml2QjHn06ILVbi8GTMg8O7ONiT4ZDwKK5lu5E92QmWkEZp2bmCdXRBuSyCF54s7IxTPl528EfWoLuWRU%3D&txtEmail=sanjay%40gmail.com&txtPassword=Welcome1234
