Remove the password


== Synopsis

Declared in header `<https://www.github.com/boostorg/url/blob/develop/include/boost/url/url.hpp#L435[boost/url/url.hpp,window=blank_]>`

[source,cpp,subs="verbatim,macros,-callouts"]
----
xref:boost/urls/url.adoc[url]&
remove_password() noexcept;
----

== Description


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.
[NOTE]

The interpretation of the userinfo as
individual user and password components
is scheme-dependent. Transmitting
passwords in URLs is deprecated.

=== Example
[,cpp]
----
assert( url( "http://user:pass@example.com" ).remove_password().authority().buffer() == "user@example.com" );
----

=== Postconditions
[,cpp]
----
this->has_password() == false && this->encoded_password().empty() == true
----

=== Complexity

Linear in `this-&gt;size()`.

=== Exception Safety

Throws nothing.

=== BNF
[,cpp]
----
userinfo      = [ [ user ] [ ':' password ] ]

user          = *( unreserved / pct-encoded / sub-delims )
password      = *( unreserved / pct-encoded / sub-delims / ":" )
----

=== Specification
