What is a username? Explained in a simple and understandable way

The so-called "username" denotes the name of a user, ie a user. In this practical tip, we explain what is so special about it and what the exact purpose of this user name is.

This is a username and that's what it serves

• On the Internet, the username corresponds to the name of the so-called "user". If you are not familiar with this term, you should read the relevant practical tip first.
• Just like your name in real life, the username is also used for identification - in this case, however, on the Internet.
• If you write several posts in a forum, the other users of the forum know that the same user is hiding behind it.
• You choose the username in most cases when you create an account. You also set a password. Note: We give you tips for a secure password.
• With some Internet services, such as IRC, registration is not successful. In this case you can choose a new username each time.
• In any case, the same username cannot be used by two different users at the same time. If the username is already assigned, you have to choose another one.
• Exception: On sites like 4chan.org you get a standard name if you do not specify a username. At 4chan you are called "Anonymous", just like any other user without your own name.
