If it bothers you to enter codes that banks send you via SMS, different web services, and others that use XNUMX-Step Verification, here's a trick you can use a lot.
Two-Step Verification or Two-Factor Verification is an additional security measure that helps us prevent someone from accessing our accounts or services, even if they obtain your password.
The idea, to identify someone, is to use one of these three possibilities: something you know, something you are or something you have.
The traditional form has been that of "something you know", ie the password. Apple started using the Touch Id (fingerprinting) system a long time ago, which becomes 'something you are' and which a few years ago was replaced by Face Id (facial recognition) in some of its devices.
But the "something you have" method is much simpler, for example a telephone. Sending an SMS should be an additional security measure as only you will receive the information for what you have: a certain phone number. Other methods of "something you have are keys, USB, etc ...
Using two steps or double factor usually involves entering the password and receiving a code via SMS. It is a code that is generated randomly and lasts a short time, so it is useless, it simply served as an additional security measure.
For some time there has been a system of automatic detection of these SMS codes in iPhones, so for example, if you are doing a bank transaction and they send you an SMS, it will appear at the top of the keyboard. Code so just click and to come in. Personally, this is one of those little things that make you thank you every time I use it, because before you had to be careful, quickly memorize the number, change the application ...
One of the wonders you have in the Apple ecosystem is that all the devices are very well connected to each other, so that you can receive SMS from the mobile phone on the iPad or Mac. In this way the iPad or Mac will detect that you have received a verification code and it will offer you to automatically fill in the field where it requests it. Then, you will bring this cool iPhone feature to the rest of your devices.
To do this, go to Settings> Messages> SMS forwarding. Inside you can indicate to which devices, which you have with your account, you want to forward the SMS.
Although it is also useful to receive SMS and read them on any device… or reply to them… for me the introduction of these verification SMS is the greatest of its usefulness.
