Password requirements
For reasons of security, passwords should comply with
the following criteria:
Eight characters minimum
Letters, numbers, and special characters
Avoid using whole words or a sequence of characters
(e.g., Anna or 123)
Keep in mind that an administrator can define the requirements to
be met by a password. The password requirements include:
Minimum length
Minimum number of different types of characters
Capital letters
Small letters
Numbers
Special characters
Maximum length of character strings (e.g., 54321 = string of five
characters)
The number of characters must match the dictionary check
Minimum number of characters changed compared to previous
password
If the new password does not meet the requirements, an error
message will be issued. This means that you have to enter a
different password.
Administrators can specify the expiration of passwords. If
you do not change your password within the valid period,
you will no longer be able to log on as that user. In this
case, an administrator needs to reset the user password
before you can log on again.
Change your password at regular intervals
