User ID's created with email @example.com in User table, can we delete?

[Prabhu6]

I'm curious how the User ID's are created in the sys_user table; now, while doing some plugin installation, roles have been added to those IDs ( email- @ example.com); can we delete those User ID's?

What does SN local user mean? Are they Service Account?

Do one thing mate, open the table sys_user_has_role and fill user with the role you want to delete from their profile.

Thank you, Sid. Right now, I am removing roles; I will decide later on the deleting option.

These are likely demo data and you should be able to delete them.  If you're not sure, look at the Last Login field to see whether anyone is actually using these accounts.  I would be very surprised if anyone is using them, and if they are, you should probably stop them from doing so, because anyone logging on to your system should be an identifiable user, and someone using a dummy account to logon is a security event by definition.

All IDs have an empty logged-in field value. Moreover, I removed the roles for those IDs. I will decide to remove/delete those IDs.

Thanks a lot for your inputs.
