Why do some names on the meeting roster have brackets around them?

To help meeting attendees know when users have joined without a Amazon Chime registered account, unauthenticated user names are displayed in brackets.

This is to help users know that the attendee typed in their name and that there was not a formal authentication process.

In the example to the right, Jane Doe typed their name in while joining from the web browser.

Other attendee types that would have brackets because they are unauthenticated are

• Dial-in attendees that dial-in using Meeting ID provided in the invite (e.g. 10-digit) — their caller ID is displayed in brackets.
• Conference room attendees joining from an in-room video system — the video system ID is displayed in brackets.
