Why does Wifi ask for a login and password when connecting from an iPad, iPhone, while a simple password is enough for Andoid?

Question

Android

There is a wifi router Mikrotik RB2011UAS
Android devices are perfectly connected to it. You only need to select the network once and enter the key (password).
But when connecting the iPad and iPhone, after selecting the network, a login and password request appears (Two fields)!
Apparently some kind of security setting in Mikrotik that Android ignores, but the apple requires.
Tell me: what to do in Mikrotik so that no login is required on Apples and the usual wifi network key is enough, or what to enter in the login field.

Answer 1

Select WPA2-PSK over WPA2-Enterprise for the authorization method.
