MATE equivalent of the default login shell?

For any MATE users out there, or anyone who may just be better informed than me: Is there a way to change the default login shell to the one MATE uses on Debian? I can’t recall what it’s called :frowning: Thanks for any help offered!

I think MATE uses LighDM as the login manager but I could be wrong as I use XFCE.

I’ll be giving it a go when I’m off work. That rang a few bells so I’m thinking you’re on to something. It’s cool to know other non default settings PureOS users!
