Modify user in app.config

I have a dll where user and password are passed through the app.config to the webservice and I would like to see how to do this so that instead of passing a hardcode a variable is passed which can then be reported to the dll in time execution. Would this be possible? I am not very expert in c # the truth that is why it is costing me but I manage two possible scenarios:

include a key that can be modified in the future from the program

the program directly modifies the value of the wsse:username and the password

But I am not able to implement any of the two options and make them work.

The app.config would be something like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="XXXXXX" value="XXXXXXX" />
    <add key="XXXXX" value="xxxxxx" />
  </appSettings>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="e3s-xxxx">
          <security mode="Transport" />
        </binding>
        <binding name="e3sxxxx">
          <security mode="Transport" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://xxxxx:443/ctxweb/secured_ssl/xxxx_waste"
        binding="basicHttpBinding" bindingConfiguration="e3s-xxxx"
        contract="E3S_XXXX.Ie3xxxx" name="e3s-xxxx" >
         <headers>
          <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
            <wsse:UsernameToken>
              <wsse:Username>miusuario</wsse:Username>
              <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">miprueba</wsse:Password>
            </wsse:UsernameToken>
          </wsse:Security>
        </headers>
      </endpoint>

Thank you very much everyone for your help.

For your first scenario I think it could help you, in my case, I have a key in the app.config that tells me which server I want to connect to:

<appSettings>
  <add key="server_al_que_me_conecto" value="y"/>
</appSettings>

That key has different values and in my connection DLL I get the value of the key and this, depending on the value, connects against one server or another (that is, I could change the value of the key and change where the application is connected at runtime).

I get the value of the key so that:

   string contra_quien_estoy_conectando = System.Configuration.ConfigurationManager.AppSettings.Get("server_al_que_me_conecto")[0].ToString();

In your case, in addition, you want to change the value of the key of the app.config in runtime and, although it is not my case, looking for a bit I have found this that you may be worth to change those values:

Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath); 
config.AppSettings.Settings["Key"].Value="Value";
config.Save(ConfigurationSaveMode.Modified);

Try this info and I hope it will be helpful. Good luck!
