In MDL-66776, emails were send upon logins on new devices, which is a great feature! We would love to force these notifications to be send (instead of letting the user decide), but sadly we can't, because there are too many cases, in which the feature is very annoying.

In my understanding, in the pretty common scenario of daily logging in on one device in the morning for example at school or university, and one other device later, for example at home, is enough to already receive two mails per day. If you use moodle on your smartphone, and on a computer at work and at home, that number will only rise.

This is a serious issue/flaw in my opinion, because it does not matter whether we send users these login emails, if they just ignore them because they are 'the norm'.
