<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>You may specify
|
||
|
|
certain characters that are not allowed in a password or you may specify that
|
||
|
|
any characters are allowed in a password (*NONE). You may restrict characters
|
||
|
|
A through Z, 0 through 9, and the following special characters: number sign
|
||
|
|
(#), dollar sign ($), at sign (@), and underscore (_).</p>
|
||
|
|
<p>You can use this
|
||
|
|
option to provide additional security by preventing users from using specific
|
||
|
|
characters, such as vowels, in a password. Restricting vowels prevents users
|
||
|
|
from forming actual words for their passwords. You can specify up to 10 restricted
|
||
|
|
characters.</p>
|
||
|
|
<p>This system value is not enforced when the password level
|
||
|
|
is 2 or 3. This system value can be changed at password level 2 or 3, but
|
||
|
|
will not be enforced until the password level is changed to a value of 0 or
|
||
|
|
1.</p>
|
||
|
|
<p>The suggested setting is A, E, I, O, and U. You may also want to
|
||
|
|
restrict special characters (#, $, and @) for compatibility with other systems.</p>

learn more, go to the password system values overview topic. If you are looking
|
||
|
|
for a specific system value or category of system values, try using the i5/OS system
