Hi,

What is the expected usage of the NewPassword (925) tag in the Logon message?
Can anyone explain a use case?

Best Regards, Bernt

Hi Bernt,

the standard use case is described in the field comment “Specifies a new password for the FIX Logon. The new password is used for subsequent logons.”, i.e. you want to change your current session password and have to provide old and new password in a single message.

I assume there is more to your question. The field is of no use for marketplaces that do not allow the users to set their own passwords.

Regards,
Hanno.

Hi Hanno,

I was thinking about a case that popped up today. It was about a customer that wants to give FIX clients a temporary initial password and when the FIX client logs on the first time requesting the clients to submit a new password replacing the temporary one. How should the use case look like for this case?

In this case, the marketplace needs to keep track whether the FIX client has successfully changed the temporary password or not. The Rules of Engagement would make NewPassword conditionally required for the first logon (until successful) and reject any attempts on subsequent logons to change the password again (or simply ignore the field NewPassword). The Logon response should indicate whether the password has been changed.
