Login Notification or Log

Hi everyone,
is there a way to get a notification each time a user logs in (via website, mobile device, app, client…)? Or can I see this in some form of log? I was thinking about whether it was possible, that the admin would get a notification in form of an email or even the user. Like “New login via device XY from IP” was detected.
Thanks for your help!

Any ideas?
