Get user's username
Your code is running on a broker's account. There is no username with brokers.
If you could get the user's name, he could run your code on 32 separate terminals with 32 separate accounts. That's not what you want, is it?

Only the Account's Client Name via "AccountInfoString( ACCOUNT_NAME )", not the MQL5 Username!
First of all thank you for your attention, so is this specific for every user? and users can access it through the metatrader interface?

I mean actually login information or any information specific to the user. Username is not a particularly necessary. However for verification, the user must also have access to this information.
No it is not specific enough to every user, because there are people with the same name all over the world! So use the other account information to make it more specific (see code below).
You said you wanted to extract the information via your EA running on a customer's machine. That is what I gave you! The customer already knows his own name and the name on his trading account! He does not need to extract it, but yes he can see it right under the Account names in MetaTrader's Navigator window.

Here is a sample of my own code that I use, but it is up to you to implement properly. I'm not offering any support on it. It is up to you to do the necessary research and learning.
