Security :: Login Form Using Either User Id Or Email Or Phone Number?

Apr 20, 2010

I have to make a login form using vb.net. The login form should either accept

Username ID or

Email ID or

Phone number

---- either of one ,and match it with the password of the corresponding record in the user table.

The user table has following column:- U_ID(varchar),mail(varchar),Phone(Number),Password(Varchar)

The form has two textfields - 1. Username

2.Password

And a submit button. If combination is correct I should be redirected to the Index page.

But I don't have to scan through all the columns of the user table to match the password.

(a)If the user enters user_id say- ID 10012 then we should be able to search only the record in the user_id column as it has alphanumeric or varchar data type and match with corresponding password.

(b)If the user enters Email id we should be able to search through the email id column as email id contains "@ and ." sign.

(c)If the user enters phone number then we should search only the phone column as it has numeric datatype.

Security :: Best Way To Store A Users Password And Username?

Jul 8, 2010

I am writing a simple plugin for IE. I need to store a password and username setting for the user who uses the plugin. I know that I can store the username/password in the registry, I can manually encrypt it using the encription classes with .NET, or I can store it in a config file and encrypt the config file. I was wondering if there is a specific pattern/mechanism that I should use to store password and username.

Login Form Not Progressing After Entering Correct Username And Password

Oct 16, 2014

My Login.aspx form in Visual Studio 2013 just seems to be 'static' after I enter the correct username and password. I don't get any errors. My Login.aspx.vb code looks like this:

Code:
Imports Microsoft.AspNet.Identity
Imports Microsoft.AspNet.Identity.EntityFramework
Imports Microsoft.AspNet.Identity.Owin
Imports System.Linq
Imports System.Web

[Code] ....

Don't I need a file name/URL to direct the user to after he has successfully logged-on? How would I script that? Finally, I only have one Web.config file (associated with Register.aspx) and that looks like this:

Code:
<?xml version="1.0"?>
<configuration>
<system.web>
<customErrors mode="Off"/>

[Code] ....

I don't need another Web.config file for Login.aspx, do I?
