What can I do with this system value?
You can specify whether repeating characters are allowed in a password. 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.
This system value has the following values:
- 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.
