What can I do with this system value?
You may specify whether repeating characters are allowed in a password or not. This option provides additional security by preventing users from specifying passwords that are easy to guess, such as the same character repeated several times.
When the password level is 2 or 3, the test for repeated characters is case sensitive. This means that a lowercase character is not the same as an uppercase character.
Possible values are:
- Characters may be used more than once (0)
The same characters can be used more than once in a password.
- Characters may not be used more than once (1)
The same character cannot be used more than once in a password.
- Characters may not be used consecutively (2)
The same character can be used more than once, but it cannot be used consecutively in a password.
