Remove the password

== Synopsis

Declared in `<https://www.github.com/boostorg/url/blob/develop/include/boost/url/url.hpp#L439[boost/url/url.hpp]>`

[source,cpp,subs="verbatim,replacements,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‐>size()`.

== Exception Safety
Throws nothing.

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

user          = *( unreserved / pct-encoded / sub-delims )
password      = *( unreserved / pct-encoded / sub-delims / ":" )
----
== Specification
* https://datatracker.ietf.org/doc/html/rfc3986#section-3.2.1[]
