It sounds like your personal meeting link has been shared with someone you don't know; the email you got from Zoom just lets us know that someone tried to join your personal meeting, but since you weren't using it on the time, you received an email notification.

You can continue to use the personal meeting link, but because we know that people you don't know may be trying to access it, you can change a few settings to secure the link. 

To edit your Personal Room's security settings,

  1. Log in to your Zoom account using your netID: https://washington.zoom.us
  2. Navigate to Meetings > Personal Room.
  3. Click the Edit button.
  4. In the Security area, choose Waiting Room, Passcode, or Require authentication to join.
  5. Save the changes to your settings.
Here's a screencast that shows that process: https://www.screencast.com/t/pwNXKfROT

Also, I'd say that it's a good practice to generate a new meeting link for most meetings, rather than using the personal meeting link. This practice, combined with additional security settings for your personal meeting room, should prevent most security incidents.

Here are a few more recommendations to protect zoom meetings from UW's central information technology site:


Set security for a single meeting while scheduling

When scheduling a meeting, you can configure security settings to:
  • Prevent participants from joining the meeting before a Host or Alternative Host arrives.
  • Require users to authenticate themselves
  • Require a meeting passcode
  • Require meeting participants to register before joining your meeting
You can configure any or all of these options.
On the Schedule Meetings page/screen, under Meeting Options:
  • Clear Enable join before host to prevent participants from joining the meeting until a Host or Alternative Host arrives.
  • Check Only authenticated users can join to ensure that all participants are logged into UW Zoom accounts.
  • Check Require meeting passcode to require passcode authentication when users enter the meeting. Passcodes can be up to 10 characters. By default, the meeting invitation will include the passcode for participants, as well as a Join Meeting link that will enter the passcode automatically for invited participants. These settings can be changed in your User Settings in the Zoom web portal at washington.zoom.us.
