By Christine Margret 6 minutes
Online messaging holds your most private conversations. Whether it’s about your work secrets or personal life, you share everything online.
Since online chats involve an intense level of personal details, therefore, no one wants the conversation to be viewed by the government, advertisers, or any third-party or cybercriminal.
The best way to keep your conversations secure is encrypted messaging or secure messaging apps. Encrypted messaging apps are the most secure messaging apps that provide end-to-end encryption to users.
The strong end-to-end encryption maintains your digital privacy, and no one can monitor or access your text conversations. Various messaging apps provide end-to-end encryption for text conversations along with other attached files and phone calls.
However, not all encrypted messaging apps are secure. In this blog, FastestVPN will explain to you the most secure messaging apps to try in 2021.
Here’s the quick rundown of the most secure messaging apps for you:
Before hopping into the most secure messaging apps in detail, let’s first figure out how encrypted messaging app works.
How the Encrypted Messaging App Works
Encrypted messaging apps work in a way that is completely secure and private to users. Encrypted text apps basically, encode your online messages that ultimately stop unintended users to access or read the text conversations.
It means that with end-to-end message encryption, no one can see your message’s content. Even the app company and government officials cannot access your online messages.
Modern and the most secure messaging apps use secure and complicated encryption algorithms, called a cipher.
Cipher-text represents your messages in the form of random symbols and meaningless characters to anyone who is not the intended recipient. Only recipients with the special decryption key can access the message content.
Why Secure Messages Apps Are Needed
Encrypted chat apps are considered as the most secure apps because they keep your information or text messages unavailable to a trespasser.
Without end-to-end encryption, your online chats could end up facing major security flaws. Your private conversations will be handed over to various malicious actors or cybercriminals.
Moreover, in case, if any encrypted messaging app gets hacked, hackers will still not be able to access users’ chats because of end-to-end encryption.
Many secure apps allow users to set time limits in case if your conversation goes to the wrong hands, the messages will automatically disappear as per your selected time limit.
Is Facebook Messenger App Secure
Facebook messenger app doesn’t offer end-to-end encryption because of the marketing activities. However, users can enable the encryption feature easily via its settings menu.
What are the most secure messaging apps in 2021?
FastestVPN tested out various apps, and here’s our round-up of the most secure messaging apps.
WhatsApp is a free and one of the most secure messaging app for Android and iOS. WhatsApp declared end-to-end encryption feature in 2016. Due to its strong end-to-end encryption, users can experience a way more secure communication.
WhatsApp currently holds around 20 million users and is captured by Facebook. In terms of privacy, WhatsApp is a secure messaging app that equally protects messages from malicious attacks and unauthorized access.
The best thing about WhatsApp security is that it never stores anyone’s conversations on the WhatsApp server. It means that if WhatsApp gets hacked, hackers will still fail to access users’ messages.
iMessage is another reliable and private messaging app for the iPhone. It offers seamless security to its users.
Besides the unparalleled end-to-end encryption, iMessage also offers another unique privacy feature. It enables users to set up how long the recipient can view a message. This unique feature is only available for iOS 10 and above versions.
The only downside with the app is that you are required to back up your messages from iMessage to iCloud.
On iCloud, all your conversations are encrypted with Apple’s encryption keys. It is possible that a hacker can access your iCloud account and read your iMessage conversations.
Viber comes third on the chart and currently serves 260 million active users. The chatting app is considered as one of the primary competitors of Skype. It is a multi-platform encrypted chatting app that works equally well on iOS, Android, and Windows.
Earlier, Viber didn’t seem to be a secure messaging app, but later, in 2016, Viber launched end-to-end encryption for users’ privacy.
The only issue with Viber is that it only provides end-to-encryption to single chat windows. Group chats are not as secure as individual chats.
The line is a Japan-based, secure texting app with over 217 million monthly active users worldwide. The line also offers default end-to-end encryption for messages and its location-sharing feature.
Line’s secure communication doesn’t involve any decoding key on its server. It means that only the intended user’s device can use the key to decrypt messages. The line encryption feature will only work when all the involved participants’ devices have enabled it.
Telegram does not offer encryption by default, but it offers MTProto protocol to encrypt conversations.
Users can enable encryption as per their needs. Once the feature is enabled, users can set time to disrupt messages automatically.
In case, if a user doesn’t enable secret chat encryption in Telegram, then all his conversations will be saved on Telegram’s server, which presents a privacy risk.
Which is the Best Encrypted Messaging App
WhatsApp is really a secure messaging app. Its strong encryption method ensures maximum protection for the users.
On the other hand, iMessage has a downside; it restores messages in the iCloud, which is less secure given the infamous iCloud hack of 2017. Viber only supports individual chat encryptions.
The line app also has some limitations when it comes to encryption, and Telegram doesn’t have default encryption function. All in all, WhatsApp comes off as the better one among the apps.
Are There Apps without End-to-End Encryption
Yes, there are many apps without end-to-end encryption. Not all chatting apps are secure. Therefore, it’s better to keep your conversations in control while using an unsecured chatting app. A few apps with no end-to-end encryption are Snapchat, GroupMe, and Instagram.
What is More Secure SMS or WhatsApp?
WhatsApp is more secure than SMS. WhatsApp offers strong end-to-end encryption that disables third-parties to access your messages’ content; that’s why WhatsApp is more protected than SMS.
All the secure messaging apps mentioned in the list are the best way to communicate safely without the fear of being intervened. For added protection, use a VPN for your connection to keep your activities from unwanted snooping. You can also read our guide to find your router IP address for essential configuration changes.
