Unknown users in my filter?

[Thomas Ljungstrøm]

Hi

I have a free JSM cloud plan, with only one user - myself.

But when I go to the project timeline and want to filter the overview on Assignee or Reporter, it gives me options for people I have no idea who is:

Alana Hansen, Jie Yan Song, Mia Ricci and Omar Darboe.

I dont know who they are; they have never been users in my account and they have no relation to this... so does anyone know why I'm seeing them?  Should I be worried that there has been a breach?

Hey @Thomas Ljungstrøm 

Have you checked the access portion of the project settings? And further to that check your user directory. 

It may be the case you allow customers to self sign up. 

Thanks,

Aaron
