You don’t have to be a high-profile executive or a secret agent to need a secure messaging app. Our daily conversations like sharing bank details for a quick transfer or sending personal photos to a loved one often include sensitive information. If you value your privacy, using an encrypted messaging app is a simple yet effective way to protect yourself.
1. WhatsApp
It’s no secret that WhatsApp is easy to use and convenient. However, what makes it even better is that it prioritizes your privacy with features like end-to-end encryption. This means everything you send and receive (voice notes, media files, text messages) stays just between you and the other person. No one, not even WhatsApp can see or hear your conversations.
You even have the option to enhance this privacy even further. This can be done by enabling features like disappearing messages and two-step verification on the app. The former allows you to set a timer for messages to automatically delete after a certain period. On the other hand, two-step verification requires you to enter a PIN to launch the app. This makes it harder for anyone to access your chats even if they have your phone.
Additionally, WhatsApp’s popularity also works in your favor when it comes to secure communication. You don’t need to convince a lot of people to switch to a different app. Chances are, they’re already using it. You can also pair it with some Android apps to enhance your WhatsApp experience.
Another important thing to mention here is that WhatsApp is owned by Meta. If you don’t trust Meta (considering its history with data privacy concerns), you might want to look at other options in the list.
2. Signal
Signal is an open-source app, which means anyone can review its code to verify the safety measures. It offers end-to-end encryption and the app is committed to collecting minimal data about you.
The privacy policy of the app states that it only stores the bare minimum, which is the data you provide (like phone number, profile information, contacts). Like WhatsApp, Signal allows you to enable disappearing messages for added protection as well.
Signal also introduces a feature called “Sealed Sender,” which hides the metadata of your communication. This means not even Signal knows who’s messaging whom. This app can also replace your phone’s default messaging app if you want to, but SMS is not encrypted by default. The person you are texting will need to install Signal as well for the privacy features to function.
3. iMessage
Social media apps often get the spotlight for security concerns, but your everyday messaging apps need protection too. Apple does a great job at this by integrating advanced security features into iMessage.
For starters, every iMessage sent between Apple devices is protected by end-to-end encryption. There are also features like iMessage Contact Key Verification that let you verify that you’re messaging the right person. It alerts you if a third party, such as a hacker, tries to access your conversation.
Apple also uses technologies like Kyber, which is a quantum-resistant encryption algorithm selected by the National Institute of Standards and Technology (NIST). It makes sure that your messages remain secure not only today but also in the future, even as quantum computing develops.
Additionally, you will have control over your conversations. You can set messages to automatically delete after a specific time, such as 30 days or a year, so sensitive information doesn’t linger unnecessarily.
4. Telegram
Telegram’s privacy works slightly differently. Not all chats on this app are encrypted by default, but it offers a privacy feature called Secret Chats to help you stay safe. These chats are fully end-to-end encrypted, so the messages won’t get stored on Telegram’s servers. Once they are deleted, they are gone for good.
Secret Chats also come with self-destruct timers, so you can decide how long a message stays visible before it automatically disappears. Additionally, each Secret Chat has a unique encryption key that you can compare with the other person to confirm that your conversation is secure.
If you prefer anonymity, Telegram allows you to sign up without sharing your phone number by using an anonymous number or email. It’s important to note, though, that Telegram group chats and channels don’t offer end-to-end encryption. These are stored on Telegram’s cloud servers. The app does have its own server-client encryption to protect data during transit but doesn’t provide the same level of privacy as Secret Chats.
5. Facebook Messenger
Messenger, another app by Meta, offers end-to-end encryption (E2E) for personal messages and calls on the app. In addition to this, Messenger includes a secure storage feature for your chat history, which keeps your encrypted messages safe on your device or Facebook’s servers.
If you ever switch to a new device, secure storage allows you to restore your encrypted chat history easily. Plus, like most other apps in our list, Messenger also supports the disappearing messages feature. These can be enabled by tapping the name of the person in the chat, selecting the Disappearing Messages option, and turning it on. Once enabled, messages will automatically disappear after 24 hours.
6. Threema
Threema takes privacy seriously. This app does not require you to provide a phone number or email address to create an account. Instead, it generates a unique Threema ID for you which keeps your identity anonymous.
All messages sent through Threema are end-to-end encrypted. Plus, the platform stores your data locally on your device instead of on cloud servers. This prevents your data from being accessed by third parties.
The only trade-off with Threema is that it isn’t free. You’ll need to pay a small one-time fee to download the app. If you don’t mind paying for your privacy, this small fee is worth it. It ensures that Threema doesn’t rely on ads or selling your data to operate.
In conclusion, not all messaging apps are created equal when it comes to privacy and security. With increasing concerns about data breaches and online privacy, it is important to choose an encrypted messaging app for all types of communication, according to the FBI. This way, you can protect yourself and even your loved ones from unfortunate events.
