Why is it important to change the security PIN on Samsung?

Now that you know how to change the PIN in Samsung, both in the phone locking system and the SIM card, we will talk about the importance of modifying your passwords from time to time. Although there is no specific timeframe, it is highly recommended that, from time to time, you change your passwords. This is one of the most effective ways to keep a mobile device safe. In the case of the Google account, the company itself tells you when was the last time you changed the password. Many users use Google services every day to save their photos, their contacts and even credit cards information using Google Pay. If you are one of them, keeping it safe should be a priority.

According to a study developed by Verizon on data breach related topics, 81% of the hacking-related breaches are due to compromised passwords.

Having someone discover your Google account password or accessing your mobile phone could have disastrous consequences. The fact of changing the PIN from time to time on Samsung or any other device makes it difficult for potential attackers to access.

How to create a PIN? Here are some tips.

As a bonus, here are some guidelines on how to set a good and secure code for all your needs:

  • Do not use the same PIN on your phone that you use on other services. This way, if an attacker discovers your secret number, they will not be able to access other personal accounts. Do not use the same code on your mobile and computer either.
  • Do not include dates or data that are easily recognizable. For example, if you have your date of birth in a public profile, like Facebook, and you use it in your Google account as a password, it is really easy to guess the password and access your data.
  • Avoid passwords that you have already used before. This will avoid using a PIN that has already been compromised in the past.
  • If possible, combine letters and numbers. You can even use symbols in many cases or uppercase and lowercase letters.
