Change Required Group Box

The Change Required group box is where you specify how much a new password must differ from the old.

Percent different from last password field

The percentage of characters a new password must contain that differ from characters in the previous password. If the value is set to 100, the new password may contain no characters that were in the previous password, unless Ignore sequence when checking for differences is set to 0. For examples of how this parameter works with Ignore sequence when checking for differences, see the following table.

Ignore sequence when checking for differences check box

Ignores the position of the characters in the password when determining the percentage.

For example, if a user’s initial password is BASEBALL12 and the Ignore sequence when checking for differences check box is selected, a user cannot choose 12BASEBALL as the new password. If the check box is deselected, 12BASEBALL is an acceptable password because each letter occurs in a different position. For examples of how this parameter works with Percent different from last password, see the following table.

For increased security, Ignore sequence when checking for differences check box should be selected.
