-  * The BIAC cluster has a separate password from your BIAC Windows account. +  * The cluster uses DHE/EAD account credentials. 
-  * If you do not already have an account, see [[biac:cluster:account|Requesting a Cluster Account]]+  * Too many account failures can cause your EAD account to be locked
-  * Password requirements +  * If you've forgotten your password, see [[biac:password|Account Passwords]].
-    * Minimum length is 8 characters +
-    * Must contain at least 3 of the following character classes (uppercase, lowercase, digit, symbol) +
-    * Must be changed at least every 180 days (same interval as your BIAC Windows account) +
-  * Use the ''**passwd**'' command __on the head node__ (hugin) to change your cluster password. +
-  * If you try to change your password on one of the nodes, you will get the following error, because of the read-only filesystem that the cluster nodes use.+
  
-<code> 
-[petty@node23 ~]$ passwd  
-ReadOnly operating system, please change your password on the head node 
-passwords are automatically sync'd every 10 minutes

-  * Once you've changed your password on the head node, there could be a slight delay before the new password takes effect for interactive sessions. 
-  * Passwords are automatically sync'd across all cluster nodes every 10 minutes.  If you find that your new password doesn't work immediately, please continue to use the old password, or wait for the sync. 
-  * If you've forgotten your password you can email [[mailto:help@biac.duke.edu|help@biac.duke.edu]] to request a reset.
