This is something most people do, but revealing your birthday on social networks can put your online security at stake. We explain why.
“Nowadays social networks usually remind us of the birthdays of our loved ones, and yet it is a piece of information that they really should not have.”
Revealing your birthday on the network puts your online security at stake. Even posting photos of the celebration, or having posts from family and friends congratulating you on your day can compromise your privacy.
You are probably wondering why it is so dangerous that everyone can know your birthday, if it is one of the first data, along with our first and last name, which we reveal when joining a social network.
The first reason is the security questions that some platforms usually use so that you can recover your password in case you forget it. Next to the name of your first pet, or the street you were born on, your birthday is one of the most common security questions. Thus, many choose it because it is the easiest to remember.
Imagine how easy it would be for a hack to find out your birthday, to answer the security question and reset your birthday. It is not uncommon that they opt for this method, and many of the tests we do in the network are used to obtain this data, reveal from How to Geek.
You may create that you are out of danger because you have never used your birthday as a security question, but you could also use it to identify yourself in a call with your service provider. Many times the birthday date is used as a password or authentication method.
