Update the system passphrase

To change the system passphrase on a Niagara 4 platform use either the Commissioning Wizard or the Platform Administration view as described here.

In the Platform Administration view, when you click System Password for any Niagara 4 platform (including a JACE-8000 downgraded to run AX-3.8U1) the window below opens.

A strong password is required (must match in both password fields). The characters you enter are obscured.

Password rules are the same as for platform users, using a minimum of 10 characters, with:

  • At least one UPPER CASE character.
  • At least one lower case character.
  • At least one digit (numeral).

An error popup reminds you if you attempt to enter a password that does not meet minimum rules.

 
NOTE: It is important to remember the system password and keep it safe. If you lose the system passphrase, you will lose access to encrypted data.
