Being without internet access away from home is a common problem, especially for those who work on the go or are traveling. apps to find Wi-Fi<\/b> They are helpful in these situations: they maintain maps of public networks and establishments that offer free internet access to customers, such as cafes, shopping malls, airports, and bus stations.<\/p>\n
Before continuing, a necessary clarification: No legitimate app can discover the password of someone else's Wi-Fi network.<\/b>. What these apps do is catalog open networks and passwords that the owners themselves have chosen to disclose \u2014 in a hotel, for example, or in a restaurant that prints the password on the menu. Attempting to access a third-party network without authorization is a crime in Brazil, as stipulated in article 154-A of the Penal Code. Below are the real apps, what they offer, and how to use them without exposing yourself.<\/p>\nWhat do these apps actually deliver?<\/h2>\n
<\/i> Map of public networks <\/strong><\/p>\n The apps show locations on the map with open or publicly available Wi-Fi, based on what other users have registered. Coverage is good in capital cities and spotty in smaller towns.<\/p>\n <\/i> Passwords released by the venues themselves. <\/strong><\/p>\n Part of the database comes from passwords that businesses publish for customers. These are not cracked passwords or passwords obtained without authorization\u2014and they may be outdated.<\/p>\n <\/i> Mobile data savings <\/strong><\/p>\n By using a local network instead of a data plan, you preserve your data allowance. This is especially useful for updating applications and transferring large files.<\/p>\n <\/i> Connection quality indicator <\/strong><\/p>\n Several apps display the speed measured by those who have already used the hotspot, which helps in choosing between two nearby networks.<\/p>\n <\/i> Integrated VPN in some cases. <\/strong><\/p>\n Some apps include VPN to encrypt traffic on public networks. It's a useful feature, usually with a data limit in the free version.<\/p>\n The three apps below were checked on the Brazilian Google Play Store. None of them can crack a protected network password.<\/p>\n O Instabridge<\/b> It maintains one of the largest databases of collaborative Wi-Fi hotspots and works well in Brazilian capitals. The app shows a map with known networks, indicates the reported quality, and automatically connects when you get close to a registered hotspot.<\/p>\n The database is populated by users who have chosen to share networks to which they have legitimate access\u2014their home network, for example. This means that some records become outdated when the owner changes their password.<\/p>\n There is a paid version without ads and with downloadable maps for offline use. On iPhone, the app is distributed under a different name and focuses on mobile connectivity, so check the app store page before installing.<\/p>\n O WiFi Map<\/b> It's the most international on the list, with registered locations in many countries. For travelers, it's useful precisely for this reason: it allows you to check airports and stations before disembarking.<\/p>\n It displays comments from other users about each location, which helps to know if the network requires registration, if it has a minimum consumption requirement, or if the signal only works inside the establishment.<\/p>\n Downloading maps for offline use and the integrated VPN are available in the paid version. The free version covers basic browsing and includes ads.<\/p>\n O WiFi Magic+<\/b> It's a Brazilian app that combines a network map, community reviews, and VPN. Because it's made in Brazil, it has reasonable coverage in smaller cities, where international competitors tend to have few registered users.<\/p>\n Like the others, it depends on what the community registers: the quality of the result varies greatly from neighborhood to neighborhood. It's worth checking the date of the last comment before going to a location.<\/p>\n The built-in VPN helps protect traffic on public networks, but check the usage limits of the free version before relying on it.<\/p>\n Step 1:<\/b> Baixe o aplicativo apenas pela Google Play ou App Store. Instaladores de sites aleat\u00f3rios que prometem “senha de qualquer Wi-Fi” costumam conter malware.<\/p>\n Step 2:<\/b> Conceda a permiss\u00e3o de localiza\u00e7\u00e3o, necess\u00e1ria para o app mostrar os pontos pr\u00f3ximos. No Android, prefira a op\u00e7\u00e3o “somente com o app aberto”.<\/p>\n Step 3:<\/b> Consult the map and check the recent reviews for each location before traveling there.<\/p>\n Step 4:<\/b> Connect only to public networks or networks whose access has been authorized by the administrator \u2014 the password of the hotel where you are staying, for example.<\/p>\n Step 5:<\/b> On a public network, activate your VPN and avoid accessing your bank account, main email, or making purchases. Turn off Wi-Fi when leaving the area.<\/p>\n An open network is a network without encryption: traffic can be observed by other people connected to the same point. Therefore, leave financial transactions and logins to sensitive accounts for when you are on your own network or mobile data.<\/p>\n Be wary of networks with names very similar to that of the establishment \u2014 it's a known scam: the criminal creates a fake point with a similar name to intercept the traffic of those who connect. If in doubt, ask the employee what the correct name of the network is.<\/p>\n Mantenha o sistema atualizado, desative o compartilhamento de arquivos e n\u00e3o instale certificados que uma rede pe\u00e7a para “liberar o acesso”.

The text of Article 154-A of the Penal Code, concerning the unauthorized access to computer systems, is available at [link\/website address]. Planalto website<\/a>.<\/p>\n No. Apps that promise this are either fraudulent or malware. Current networks use encryption that cannot be broken by a mobile app, and accessing someone else's network without authorization is a crime under Article 154-A of the Penal Code.<\/p>\n<\/div>\n From users who have shared networks to which they have legitimate access, and from establishments that disclose their passwords to customers. Like any collaborative database, it contains outdated records.<\/p>\n<\/div>\n It's acceptable for general browsing, as long as you avoid banking, shopping, and logging into important accounts. Activate a VPN whenever possible and be wary of networks with suspicious names.<\/p>\n<\/div>\n Generally, not for basic consultation. Registration is usually only required to contribute new points or to subscribe to paid features.<\/p>\n<\/div>\n Yes, but it's usually a feature of the paid version. You download the region in advance, while you're still connected, and check it later offline.<\/p>\n<\/div>\n Data usage increases when the app runs in the background with GPS enabled. Maintaining location tracking only when the app is open significantly reduces this usage.<\/p>\n<\/div>\n A good Wi-Fi map app solves the problem of finding a connection in unfamiliar places, without promising what it can't deliver. Instabridge, WiFi Map, and WiFi Magic+ fulfill this role using collaborative databases of public and open networks.<\/p>\n Download only from official app stores, activate VPN on an open network, and never try to access someone else's network without authorization.
