Digest platform authentication
Digest platform authentication is the only method for a QNX-based host or Linux-based Supervisor, and is an alternative for a Windows-based host. The associated Authentication dialog lets you change the single platform account credentials (user name and password), as shown here.
NOTE: Credentials are case-sensitive. For example, PlatUser and Platuser are not the same.

CAUTION: When commissioning a new JACE, always change platform credentials from the defaults! A JACE installed with default platform credentials is extremely susceptible to unauthorized intrusion! Further, in
In digest authentication, platform user name can be as follows:
User Name
- If QNX-based host, a maximum of 14 alphanumeric characters (a - z, A - Z, 0 - 9), where the first character must be alphabetic, and following characters either alphanumeric or underscore ( _ ).
- If Windows-based host, any number of alphanumeric characters, including hyphens and underscores.
Password
- In digest authentication, platform password for both QNX-based and Windows-based hosts can be any combination of alphanumeric
characters, including common punctuation (
! @ # $ %). This permits a strong password.
NOTE: A "strong password" is highly recommended. Some basic guidelines on strong passwords:
- Use both upper and lower case.
- Include numeric digits.
- Include special characters.
- Don't use dictionary words.
- Don't use company name.
- Don't make the same as the user name.
- Don't use common numbers like telephone, address, birthday, and so on.
Usage Notes
In digest authentication, when changing credentials (user name or password, or both), your new credentials become immediately effective when you click Finish. If you previously had "Remember these credentials," selected in the Authentication login dialog, the cached credentials are automatically updated.
