+  <p>When your key expires, it becomes invalid. This means:</p>
+
+  <list>
+    <item>
+      <p>It can no longer be used to encrypt and decrypt messages.</p>
+    </item>
+    <item>
+      <p>It cannot sign other keys or receive signatures from other
+      keys.</p>
+    </item>
+  </list>
+
+  <p>Depending on how long you want your key to be valid, you can
+  <link xref="key-expiration-setting#set">set an expiration date</link> for it. By
+  default, <app>Passwords and Keys</app> sets all keys to be valid forever,
+  that is the keys never expire.</p>
+
+  <p>The expiration date on a key can be
+  <link xref="key-expiration-setting#change">changed</link> anytime, even after
+  the key has expired. However, if you want to stop using the expired key, you
+  should <link xref="key-delete">delete</link> or
+  <link xref="key-disabling">revoke</link> it.</p>
+
+  <note style="info">
+    <p>If you have any messages encrypted with an expired key, you must change
+    the expiration date on the key to decrypt such messages before deleting or
+    revoking it.</p>
