+# Change your submit server initial password
+
+Using the **Username** and **Initial password** you receive via
+email in [step 3](#step_3), you need to login to the [IOCCC submit
+server](https:/submit.ioccc.org).
+
+**IMPORTANT NOTE**: You must change your password **WITHIN 72 HOURS**
+from when one of the [IOCCC judges](../judges.html) sent that email.
+
+**NOTE**: The [IOCCC submit server](https://submit.ioccc.org)
+is only ready for submissions **ONLY WHEN THE CONTEST IS [open](../status.html#open)**.
+
+See [current status of the IOCCC](../status.html) for details on the contest status.
+**IMPORTANT NOTE**: When the contest is [closed](../status.html#closed), the
+[IOCCC submit server](https://submit.ioccc.org)
+may be offline and unreachable as a web site.
+
+To login and change your password, open [https://submit.ioccc.org](https://submit.ioccc.org)
+in your browser.  It should look like this:
+
+<img src="../png/submit-server-login.png"
+ alt="submit server login screen"
+ width=710 height=562>
+
+The login is the UUID you were provided when you registered for the IOCCC and
+the password is the initial password you were provided with. Click "Login".
+
+If this is the first time you have logged in with this UUID, you will
+be required to change your password.
+
+Assuming everything is fine, it should look something like:
+
+<img src="../png/submit-server-first-login.png"
+ alt="submit server password change required"
+ width=710 height=808>
+
+As you can see, you have to change your password. Put in your login (UUID
+username), your old (initial) password and a new password. For instance:
+
+<img src="../png/submit-server-change-passwd.png"
+ alt="submit server changing password"
+ width=710 height=808>
+
+Click "Change Password".
+
+Once this is done, you will be able to log in again with your UUID
+username and new password.
+
+When the is [open](../status.html#open), proceed with
+[Step 5: Obtain and compile the latest mkiocccentry toolkit](../faq.html#step_5).
