Remove the password.
This function removes the password from the userinfo if a password exists. If there is no userinfo or no authority, the call has no effect.
The interpretation of the userinfo as individual user and password components is scheme-dependent. Transmitting passwords in URLs is deprecated.
assert( url( "http://user:email@example.com" ).remove_password().authority().buffer() == "firstname.lastname@example.org" );
this->has_password() == false && this->encoded_password().empty() == true
userinfo = [ [ user ] [ ':' password ] ] user = *( unreserved / pct-encoded / sub-delims ) password = *( unreserved / pct-encoded / sub-delims / ":" )
