i want otp auth using session.

Sachin Singh · Answer

you need to put your each method inside session or use session inside Page Load event , when you are validating the OTP put a flag like isValidated inside session and use it later in each page public void OTPValidation() { // your code session[ "isValidated" ]= "True" ; } protected void Page_Load(object sender, EventArgs e) { if (Session[ "IsValidated" ] == null ||Session[ "IsValidated" ].ToString() != "True" ) Response.Redirect( "FrmLogin.aspx" ); else { // other code } }

Sachin Singh · Answer

yes, you need to use session on each page like this now protected void Page_Load(object sender, EventArgs e) { if ( Session["rNumber"].ToString(); == null ) Response.Redirect( "FrmLogin.aspx" ); else { // other code } }
