Anonymity in the twenty-first century is all about your privacy on the Internet, not staying at home alone and no one knowing what you're doing.
1. Use messaging app called Signal
The signal is without a doubt the best private encrypted messenger (no, it is not Telegram). The main feature of it is that it is a simple messenger with privacy and cryptography. His encryption is incredible, far superior to anything else available. Of course, a powerful organisation will detect your use of a signal, but there is nothing better or more useful for private communication than it.
About Signal:
Signal's software is open-source and free. Its mobile clients are released under the GPL-3.0 licence only, while the desktop client and server are released under the AGPL-3.0 licence only. The official Android app generally makes use of the proprietary Google Play Services (which are installed on most Android devices), but it is designed to function without them. Signal has an official iOS client app as well as desktop programmes for Windows, macOS, and Linux (although registration requires an iOS or Android device).
2. Use Tor
Tor is the world's most popular and dominant browser, with incredible metadata resistance. Anyway, for some reason, Tor does not provide complete anonymity, as some believe, but it is still the best. The browser only works over TCP, and you can't sign all of the sites from Tor because some of them block access. Because it does not provide 100% performance, it is always used for dual or trial purposes, such as VPN tunnels, but it is ideal for mobile.
About Tor:
Tor, which stands for The Onion Router, is free and open-source software that allows for anonymous communication. It routes Internet traffic through a free, global volunteer overlay network of over 7000 relays to conceal a user's location and usage from anyone performing network surveillance or traffic analysis. Tor makes tracing a user's Internet activity more difficult. Tor's intended use is to protect its users' personal privacy, as well as their freedom and ability to communicate confidentially, by using Tor exit nodes to mask their IP addresses.
3. Don’t wait anonymity from VPNs
VPN does not provide anonymity. That is correct. It offers some useful seasonal services, such as access to sites that are blocked in your country or other related services when your access is restricted but you still need to go there. It simply alters your IP address. For example, Tor distributes your traffic through tor nodes located throughout the internet, whereas VPN retranslates your traffic to their server, so your internet provider can still see what you're doing, and you don't change anything on your end. Remember that if VPN servers are hacked, hackers will have access to all of your traffic.
4. If possible, use zero-knowledge services.
Maybe you didn't know, but internet behemoths like Dropbox, Google, and Office 365 can read everything you save and write, and we know this from Snowden reports, so they work closely with the FBI. These services provide no privacy. You can encrypt everything before using these services, but zero-knowledge sites are preferable. SpiderOak (as a Dropbox replacement) and Protonmail (private email) are two examples; neither is a panacea, but they are far superior.
About SpiderOak:
SpiderOak is a collaboration tool, online backup, and file hosting service based in the United States that allows users to access, synchronise, and share data via a cloud-based server provided by the same name. Its first product, an online backup service dubbed "SpiderOak ONE," debuted in December 2007.
About ProtonMail:
Proton Mail (also spelled ProtonMail) is an end-to-end encrypted email service founded in Geneva, Switzerland in 2013. Unlike other popular email providers such as Gmail and Outlook.com, it uses client-side encryption to protect email content and user data before it is sent to Proton Mail servers.
5. Think first, then post.
This is a very simple but crucial step. Everything you've ever posted can be tracked down and used against you. It starts with text posts and progresses to photos, addresses, mobile phones, videos, date of birth, full name, and so on. Do you want to remain anonymous? — Do not post, do not use your real name, do not use your real information, and always keep control of what you are doing while surfing the internet.
6. Always double-check app permissions.
Apps typically ask for permissions that are required for the app's normal operation, but they can also do strange things. They are constantly collecting information about you in order to create large data collections — mostly for advertisers, but the FBI can easily obtain this information, as can any other skilled person. It's amusing when a simple app (at first glance) requests a microphone, your geolocation, or your address book; better not to use these apps; it's difficult to stop all of these on IOS, so use Android.
7. Install an ad blocker.
Any of the ad blockers should be used. When you click on ads, they collect data about you, your computer, browser, and other information that can be used against you; don't give them that opportunity. Simply download one of the many extensions available.
8. Get rid of your home assistant
Home assistants have grown in popularity in recent years, but the main issue with them is that they hear and collect everything you say and send it to their servers, which is a perfect crime, isn't it? Nothing to say here, just use it.
