    <div class="m_-7818446848404833229m_-6753321638508112059moz-cite-prefix">The id seems recoverable from the
      w2web.users file.  However, the password seems not easily
      recoverable (as it should be!) as the perl documentation says
      "There is no decrypt function" [1].  Therefore, deleting
      w2web.users [2] (or .w2web) is the way to do it.<br>
      <br>
      First, you might want to backup the .w2web folder.  For example:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ cp -r ~/.w2web ~/.w2web_old<br>
      <br>
      Or at least, you will probably want to get and write down what the
      port and host that are in the w2web.conf file before removing the
      .w2web folder:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ cat
      ~/.w2web/computername/conf/w2w<wbr>eb.conf | grep -E 'port|host'<br>
      port=7890<br>
      host=localhost<br>
      <br>
      Next, remember to kill all currently running versions of w2web.
      For example:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ ps -e | grep w2web<br>
       4089 ?        00:00:00 w2web<br>
      username@computername:~/Deskto<wbr>p$ kill 4089<br>
      <br>
      For example, my username is user1 and password is 1234.  The
      username is clearly seen in w2web.users and 9XDKy48uHtMo6 is the
      hash for my 1234 password:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ cat
      ~/.w2web/computername/conf/w2w<wbr>eb.users <br>
      user1:9XDKy48uHtMo6<br>
      <br>
      Just the w2web.users file was removed. For example with:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ rm
      ~/.w2web/computername/conf/w2w<wbr>eb.users <br>
      <br>
      Next, I was able set a new id and password, but I used the same
      ones again.  I also used the port and host that I had before in
      the w2web.conf file:<br>
      <br>
      username@computername:~/Deskto<wbr>p$ w2web<br>

              <p>Dear Shamik</p>
              <p>The userid and password are generated when you start
                for the first time the w2web interface by typing in the
                unix terminal: <br>
              </p>

              <p>One easy solution is to remove this directory: rm -f
                .w2web</p>
              <p>Then type: w2web and answer the questions which will
