I wanted to create system account so that with single common username and password or token anyone can login to pactflow

System accounts don't have usernames/passwords and are not designed for use by users. They also dot have access to the UI. Using them (or any user) in the way you intend would be a breach of our terms and conditions

Hi Matt. We want something account/group level. So, that can be accessed within a single team and can be accessed with token or something.

What is your use case? Perhaps we start there and I can help. For clarity, are you using PactFlow or the open source Pact Broker?

Pactflow.io for POC but we have license one also its undergoing security pipeline.

So you would usually create a Team (in the Settings page) and assign users (and applications) to that team.

I don't want login like xyz1@abc.com , xyz2@abc.com . etc .What I want group wise login it should show group username login instead of respective user.

I'm still not following. If the user has an email, you can invite them as per the article shown. There is no such thing as a "group login". The article you linked is just adding single users (pact@dius.com.au might be confusing you?)
