Security tips for public Wi-Fi networks

Today there are many public places that offer free Wi-Fi connections, such as trains, shopping centers, stations, or cafes. We explain the dangers of using them and how you should protect yourself.

The free Wi-Fi connections that you can find in public places offer us a practical way to connect to the network without having to consume data from our operator’s data plan. Sometimes it is the only alternative for your laptop or tablet.

However, these public Wi-Fi connections are not at all secure. Here we explain why, and also how you should proceed to make everything more secure and not expose your device and your data to hackers.

Many coffee shops seem to have become the open offices of the 21st century. Even before the COVID-19 coronavirus crisis, it was easy to visit any Starbucks store and come across a sea of ​​users with laptops or iPads.

Now, although many try to seek some privacy in the work they are carrying out, the truth is that the Wi-Fi connection in a public place like the one they are using is not secure and will be exposing them to other types of dangers.

Why is public Wi-Fi not secure?

The free Wi-Fi connection has a hidden cost and is called security. While we like the idea of ​​being able to roam around a city by connecting to multiple Wi-Fi hotspots at no cost, this is certainly dangerous, as most of these networks are not encrypted.

In order to facilitate connections and avoid administration or supervision, these access points generally do not require a password to connect. When you connect, a web page appears asking you to enter an email address.

The problem with this is that the connection between your device and the access point is not encrypted. Therefore, some data will be sent in the form of plain text, which means that anyone could spy on your actions.

Worse still, they could set up their own access point and call it something like “Starbucks wifi.” Then people will connect to it without hesitation, giving the criminal easy access to all your unencrypted data or relevant information from you.

What are the dangers of using free wifi?

These fake networks look real and allow you to access the Internet as you normally would, but all they do is spy on you. Sooner or later, they will ask you to download something innocent looking that will contain malware to take over.

Another danger is that the Wi-Fi provider you connect to does not securely store the data that you used when registering. Sometimes these servers store the information on an Amazon server without a password, exposing everything to anyone.

Security tips for public Wi-Fi networks

Please note that when you log into any network, the device will store those details so that you can automatically connect again when you are within range of the network or come back another day.

For trusted networks like those in your home or office, this is fine. But when you do it from anywhere, this can turn against you. The fake network can impersonate another network to get the relevant information from your phone or device.

How can I make the public Wi-Fi connection secure?

The answer seems obvious: using a VPN connection.

A virtual private network (VPN) creates an encrypted connection between your device and a secure network server. If this sounds complicated, it really is not. Just install the VPN app and then enter your login details

Almost all VPN apps have a quick connect button that selects the closest or fastest server and it only takes a few seconds to connect.

The best apps have an option in the settings to automatically connect whenever your phone connects to public (unsecured) Wi-Fi, so you’re protected even if you forget to enable the VPN.

There are many providers and a wide variety of options, but you will find a comprehensive buying guide for this year’s best VPNs with our recommendations.

Two of the services are NordVPN and ExpressVPN.

Of course, the ideal solution would be for access point providers to enable encryption on your service, but this is not as simple as it sounds. As always, the biggest security threat lies in the need for convenience.

Security tips for public Wi-Fi networks

Most of these venues are informal spaces for customers, meaning they want to log in and log out quickly and seamlessly. Having to enter a password (or worse, a username and password) may not be that easy for some.

Although some hotels, restaurants, and other establishments already use encrypted Wi-Fi, in many cases the responsibility for protecting personal data rests firmly in your own hands.

One option is to simply avoid using any website or app where sensitive data is used while using the public Wi-Fi connection. But since this is inconvenient, the most feasible will be to use mobile data on your phone instead of Wi-Fi.

This is an encrypted connection, and you can generally set up a personal access point so that you can share that internet connection with a laptop, tablet, or any other worthwhile device.

Finally, it should be noted that some applications will use encryption even if the Wi-Fi connection is not encrypted. Banking apps are a good example, plus there are also messaging apps and email services that use their particular encryption.

If you want to see the information related to the date of your account registration, carefully read the following steps where we show you how to see this.

Steps to see when you signed up for Instagram

  • To do this, just click on the photo of your profile in the lower right part of the screen, now locate the three horizontal lines that are above and to the right, right at the end, you will see the option “Settings“, when you press on it you will see all system settings.
  • Go to “Security” and look for the section “View Account Data“. Click on the option mentioned above, when you click on “Access data”, your account data will be displayed. In fact, the information related to the registry will be displayed right at the top.
  • Under “Account Information”, the “Date you joined” section will appear. This is where you will see exactly the day, date, and time you registered on the Instagram platform.

Know when someone else created an account on Instagram

Although it is possible to search for a person on Instagram by their phone number, the company takes the issue of privacy very seriously, for this reason, it is very difficult to access the personal information of other users. Therefore, if you want to know the exact day that someone created an account on Instagram, it may be difficult for you.

Indeed, unlike seeing our personal information, seeing that of other users is somewhat more complicated. Even so, we can always access the basic tricks of a lifetime, that is, see a person’s first post to estimate the date their account was created.

It is true that most people share uploading aspects through social networks. In addition, it is very rare for users to delete their first publications, for this reason, it is very valid to go down to the first publication. This will allow us to see an approximate date of account creation for a person you follow.

View a person’s first post to estimate their Instagram sign-up date

This can be done directly from the App application on your mobile or using Instagram through an emulator, but if you want to speed up the process, even more, it is better to use a computer through the browser. Once on the computer, go to the source you want to see, there leave the “Space” key pressed in order to go down to the last publication.

You can also press the middle mouse click and point the cursor down, this being one of the fastest ways to get off a website. Once you reach the end of the posts, you will see the first photo or video that the user uploaded. Just click on the said photo and see the date that should appear immediately After the likes.

How to check if an email address exists and is real - Quick and easy

The process of verifying an email address is very important when we expect a quick response or want to be sure that the recipient received our message. For this reason, we recommend you read this article where we explain how to verify if an email address exists and is real.

What is an email address?

An email address is a name used to send and receive email messages over the internet. The process of creating an email account is simple; In this sense, each user has a unique email address with which they can be identified by means of a name and a domain.

The user can select a unique username. While the domain refers to a provider where the registration of the email address is made. Both the username and the domain are linked using the “@” sign. Therefore, an email address is expressed as follows: username @ domain

How does email work?

The operation of email is similar to that of a conventional email. The particularity of electronic mail consists of the presence of a network of servers where the messages remain temporarily until they reach the recipient. Additionally, users can easily change their email addresses through an “alias”.

How to check if an email address exists and is real - Quick and easy

Hence, e-mails can be efficiently transmitted through an electronic communication system. Usually, an email message contains text and multimedia content. To send a message successfully, the email address of the sender and recipient, the subject, and the message are required.

Check if an email address exists

Generally, in order to create a temporary email or when the email address is not real, we receive an automatic response in which we are informed that the server could not receive the message we sent. When this does not happen, it is necessary to follow the procedures that we explain below.

The email address scheme

First of all, it is necessary to verify if the email address has a scheme that includes a username, the sign “@” the domain, and the extension. Generally, the domain name is Gmail, Hotmail, outlook, or yahoo; while the extension can be .es, .com, or .net.

If the email address you want to verify does not comply with the previous scheme, it is very likely that it does not exist or is not real.

Use a testing tool

A simple and very fast way to verify if an email address is real or exists is to access the verified email website. There, you write the address you want to check and press the “ verify email ” button for the web page to output a result. If you see the word “Ok” in blue it means that the address exists. The word “Bad” in red indicates that the email address does not exist or is not real.

Verify email address based on domain

If the email address is from Gmail, you can access the Google account recovery wizard. Then, click on “I have forgotten my password”, write the address you are going to verify, and press “continue”. If you see an error, then the address is not real or does not exist.

To verify a Microsoft email address, you can access the password recovery section. Then, click on the option “I have forgotten my password“, enter the email address and resolve the captcha. Finally, click on “Next”. If you see an error, then the email address does not exist or is not real.

Check if the domain exists

In order to check the existence of the domain, you must type in the Windows search engine “cmd“. Click on the application and in the new window type ping domain_name.com and press the “Enter” key. The Windows operating system will issue a response and you will know if the domain exists or not. If the domain does not exist, the email address you are verifying is false.
