Is there a way to change the username I use when entering server?

I want to change the username I use when entering the server. Is there a way to change ? I know theres a /rename command but it will be waste of time and tiring for using this command every time.

What are you trying to do exactly? Use a different name whilst still using your registered account?

You could check some details here on the relevant section on the Account Management Guide:

@wiki

Renaming Your Account

You can also request an account rename. However, it will only be acknowledged when necessary. For example, if you don’t like your account name, if you want to change it just for fun, or something else; your account rename request will not be acknowledged.
