Apple has always been a company concerned with security and privacy, much more than its rival Google. Now we are going to tell you what it is for and how to configure the two-step verification of iOS 9, which is an interesting addition to the operating system to maintain our ID from Apple safe .
Don't forget the stolen celebrity photos scandal on iCloud, which caused Apple to take account security more seriously. So, a few months later, a new authentication system arrived .
Two-Step Verification in iOS 9 can get a little cumbersome, but it prevents us from stealing data or making unauthorized purchases. So let's get to know it in depth, and then find out how to activate it .

What is two-step verification?
The two-step verification of iOS 9 asks us to enter an additional code in certain accesses to our Apple account, apart from the password. We receive it by SMS (it is mandatory to give a phone number) or on another iOS device. With this system, we won't need to use security questions again, and no one can impersonate us just by finding out our password .
The confirmation code we are asked for in any of the following cases:
- Apple Account Managements.
- Access the iCloud.com web with a new device.
- Login to iMessage or FaceTime.
- Buy iTunes, the App Store, or iBooks from a new device.
- Request help from Apple Account Support.
To use two-step verification in iOS 9 we must save a security code. We have to keep it safe (better to print it), because without it we can lose our Apple account in case of problems .

How to set up two-step verification?
It cannot be said that the process is too complicated, but it does have a lot of steps and we must pay attention to itSince iOS 9's two-step verification is optional, it's normal to require a bit of effort from those concerned. These are the steps to activate it:
- Go to the Apple ID website and sign in as normal. Obviously, you can ask for a password recovery, but you'll have to be more careful in the future .
- Then you have to choose the option " Start " in the " Verification in Two steps":

- Now you have to answer your security questions. You can restore them if you have forgotten them, but pay attention, because with two-step verification it will not be as easy to solve a mistake .

- You will be presented with a brief explanation of what two-step verification is, and you will be asked your phone number to activate it:

- You will receive an SMS to your mobile (it doesn't have to be an iPhone, don't worry) with a 4-digit number that you must confirm:

- If you have any additional iOS device, you can also activate it to receive verification codes optionally. You should now write down the recovery key on a piece of paper or print it out, as Apple does not advise saving it on your computer:

- Many users do not write down the recovery key, despite its importance in order not to lose their account. That's why Apple asks you to enter it as confirmation that you've saved it:

- You've finished the process, confirm that you agree to activate two-step verification, and you should have it available:

However, if you have made recent changes to your account, Apple will put your request on holdFor example, if you did not know the password or the secret questions. In a few days it will send you an email so that you can finish registering in this new authentication system .
So now you know what it's for and how to set up two-step verification in iOS 9. It's a mechanism that provides a lot of extra security, and it prevents problems with your Apple account, so it's worth using if you're worried about it .
