I would like to disable the auto-logon feature on my Linux Mint 19 Cinnamon box.

I have tried all the answers to [This][1] question (same question, older Mint)

None have worked.

How do you disable auto-login on Mint 19 Cinnamon?

Thanks a bunch!

[Edit] seems like questions about this is frowned upon.
Thanks @inquisitive_lurker and @Andrew F for pointing me in the right direction
