As you probably already know, in recent months from Apple they are getting quite serious in terms of security, in order not to have problems and avoid scandals like those of other companies, and for this reason they have recently wanted to take measures also with in order to protect developers and their Apple IDs.
In this way, as we have learned, apparently if you pay the firm's developer fee, it seems that you will need to have two-step verification active on your account, in order to increase speed and reduce unwanted access to accounts, which can end badly.
If you are a developer, you will have to activate two-step verification
As we have been able to know thanks to the information of 9to5Mac, It seems that recently from Apple they have been sending a series of emails to users of Apple IDs for developers who do not have active double factor verification, indicating that as of February 27 it will be mandatory:
In an effort to keep your account more secure, two-factor authentication will be required to sign in to your Apple developer account and to Certificates, Identifiers, and Profiles beginning February 27, 2019.
In this way, as you may have seen, Apple's idea with this is to make all accounts more secureBecause this way they can be stopped in a relatively simple way, and that should not matter much to the developer, attacks and fraudulent access to accounts, which also in the case of these accounts can bring more problems than in conventional ones.
And, for those who do not quite like it for some reason, say that this should be done basically for pure account security, and also, as Apple has officially detailed, "This ensures that the only person accessing the account is you, in addition to allowing you to control all accesses".
