1. Open BlueStacks multi-instance manager. Click “New Instance“.
   
2. Select which instance to create:
   Fresh instance – instance with the new Google account (used to run multiple applications with different Google account. e.g. running Whatsapps with two different numbers).
   Clone instance – instance with the same Google account. (used to run multiple applications with the same Google account. e.g. Running Whatsapp and Facebook at the same time).
   
3. Click “Start” button to start that instance or create the shortcut to desktop and start via short cut as sometimes the instance cannot start directly from BlueStacks multi-instance manager.
   

Questions

1. Can I run 2 instances of Bluestacks at the same time, 1 in “Big-Boss” account, another in “Office” account?
   •  No, only 1 user (either “Big-Boss” or “Office) can run multiple instances of Bluestacks.
2. Can I run 2 instances Memu of at the same time, 1 in “Big-Boss” account, another in “Office” account?
   • The same Memu application cannot running on different Windows accounts.
   • But Memu can run on different windows account using 2 instances. It did work but both Memu instances running on 2 different google accounts.
   • However, for Whatsapp,  both Memu instances cannot use the same Whatsapp account.

The VB.Net code should be as follows:-

MSConn = New SqlConnection()
If sAUTHMODE = "WIN" Then
    MSConn.ConnectionString = "Data Source=" & sSERVER & ";Initial Catalog=" & sDATABASENAME & ";User ID=" & sUSERNAME & ";Password=" & sPASSWORD & ";Integrated Security=True" 
ElseIf sAUTHMODE = "SQL" Then
    MSConn.ConnectionString = "Data Source=" & sSERVER & ";Initial Catalog=" & sDATABASENAME & ";User ID=" & sUSERNAME & ";Password=" & sPASSWORD & ";Integrated Security=False"
End If

Otherwise, one of these error messages will appear:-

• Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication.
• Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

Problem

To log into a WordPress Site, user name and password are required.

Hacker can obtain user name from the name of author in blog post, then goto WordPress default log-in page — https://your_domain_name.com//wp-admin/ , hacker will guess password to log into your WordPress site, hence “brute force”.

In a minute, if a hacker can guess 10 passwords then in a day, hacker can try 14,400 different passwords (10 x 60 x 24 ) to try to log into your WordPress site.

It is a matter of time, the hacker can guess the correct password.

Solution: use “Loginizer Security” plug-in to prevent brute force attack

1. Install plug-in “Loginizer Security“.
   
2. Under “Blacklist”, enter range of IP address that is not in your home country. This will reduce brute force attack significantly.
