**Your software**  
My Mautic version is: 4.2.2  
My PHP version is: 7.4.33  
My Database type and version is: ySQL/MariaDB version 10.3.31-MariaDB-log-cll-lve

**Your problem**  
My problem is: i’m using a single mautc installation to track visitor from all my websites.

This is my setup:  
I have installed Mautic on [https://abcde.domain.com/m/](https://abcde.domain.com/m/)

And i’m tracking only logged users on my 30+ websites:

- [https://www.domain1.net](https://www.domain1.net)
- [https://www.domain2.net](https://www.domain2.net)
- [https://www.domain3.net](https://www.domain3.net)
- [https://www.domain4.net](https://www.domain4.net)
- …
- [https://www.domain30.net](https://www.domain30.net)

i just noticed that when i access one or more domains as logged user mautic creates different anonymous leads and then creates different cookies with different mtc\_id into for each website tracking all of them separately.

is it possibile to share the same mtc\_id across all websites?

thanks and best regards

I thought, no there is no way to use same mtc \_id.
