wordpress security

Leaking the username is not considered a security risk. If you have a strong password, it doesn’t matter who knows what your username is.

Anecdotally, compare that to almost every email provider where your email address (known by friends, family, and strangers alike) is your username.

Just for the sake of variety, a few more words on the matter at https://www.ads-software.com/support/topic/security-35/#post-5342725 and https://www.ads-software.com/support/topic/wp-431-still-allows-visibility-of-admin-usernames-continued/#post-7267357

is there a way I could hide it ?
