This field determines the length of the random part of the generated license key. The length you enter here will be a major factor in determining the maximum number of unique licenses possible.

For example, if you enter 14 here SPBAS might generate a key that looks like this:

SPBAS-1a2b3c4d5e6f7g

To break this down:

&lt;b&gt;SPBAS-&lt;/b&gt; license prefix
&lt;b&gt;1a2b3c4d5e6f7g&lt;/b&gt; license length
