Troubleshooting automatic login problem in VB 2013 settings

For my application, I am utilizing the most recent version of Awesomium's WebControl. The goal is for it to automatically log in when it reaches "accounts.google.com/ServiceLogin" by executing some Javascript. In my.settings.java file, I have the following code:

"document.getElementById('Email').value='1'; document.getElementById('Passwd').value='2'; document.getElementById('signIn').click();"

The email is represented by '1' and the password by '2. When the document is ready, this code is triggered:

Private Sub WebBrowser1_DocumentReady(sender As Object, e As Awesomium.Core.UrlEventArgs) Handles WebBrowser1.DocumentReady
    If WebBrowser1.Source.ToString.Contains("accounts.google.com/ServiceLogin") = True Then
        WebBrowser1.ExecuteJavascript(My.Settings.java.ToString)
    Else

    End If

I'm unsure why this implementation isn't functioning as expected. Copying the script directly like so works perfectly:

WebBrowser1.ExecuteJavascript("document.getElementById('Email').value='1'; document.getElementById('Passwd').value='2'; document.getElementById('signIn').click();")

The reason behind saving the code in my.settings is that I start with it in a textbox. After prompting the user for their credentials, I replace '1' and '2' with the inputted email and password, respectively. This modified text is then saved in my.settings.java. By doing this, the application can retrieve the customized Javascript for each user instead of hardcoding it. Is there an error in my code or an alternative method using Awesomium? Additionally, I usually refer to Awesomium's WebControl1 but changed it to WebBrowser1 for consistency. Apologies if this question seems basic, I'm still learning and have limited experience with Javascript.

When it comes to sensitive data like passwords or emails, I never rely on my.settings. Instead, I always encrypt them in an XML file using a secure encryption method. Here is a simple yet dynamic encryption function that I use:

Public Function Encrypt(ByVal plainText As String) As String
    Dim passPhrase As String = **My.Computer.Name.ToString**
    Dim saltValue As String = **My.Computer.Info.OSFullName.ToString**
    (...)
End Function

Public Function Decrypt(ByVal cipherText As String) As String
    Dim passPhrase As String = **My.Computer.Name.ToString**
    Dim saltValue As String = **My.Computer.Info.OSFullName.ToString**
    (...)
End Function

Although this method adds a layer of security, it's still not foolproof. The best practice is to have the user input their password directly. Regarding your query, if I grasp it correctly, you should create profiles and store them in files or a database instead of relying solely on settings or registries. This allows users like "John" to select their specific profile when using your program.
