Michal Ždanský In March of last year, Apple first introduced two-step verification for signing in to Apple ID. In addition to entering your own password, this consists of filling in a code sent to one of your devices. The user is thus protected in the event that someone else manages to obtain their password, for example through phishing, which is not unusual for Apple users.
Server & Hosting AppleInsider noted that in addition to signing into an account in the App Store, Apple has extended two-step verification to the iCloud.com portal with web apps for calendar, email, iWork and more. Until now, web applications could be accessed by entering the Apple ID password. For some users who have activated two-step verification, a four-digit code is now required, which Apple will send to one of the devices associated with the account. Only after entering it will the user gain access to their applications on iCloud.com.
The only exception here is the Find My iPhone application, which is unlocked even without entering a four-digit code. This makes sense since the device that would otherwise have been sent the verification code could be lost and Find My iPhone is one of the ways to locate the lost device. Verification is not yet required for all users, which means that Apple is either testing the feature or rolling it out gradually.

Until now, I thought that the Czech Republic was not among the supported countries for two-factor authentication.
You were right, yesterday I tried to search according to the instructions, but really two-phase verification is not possible in the Czech Republic.
