Hi,
Thanks for your post on the community forum. I'm Nik, an independent advisor here to assist you with this.
You get this message when you try joining a team meeting with two devices.
If you are not connected with two devices, then try transferring the meeting on your device and change the Team account password to avoid any misuse of your account.
If your admin has enabled the self-service password reset from the back end, then users can change the password on their own.
