![]() ![]() iMessage is also not open source, which is a black mark in the privacy community. Messages sent via SMS to Android and other platform users aren’t secure. A downside is that only messages between iPhone users are end-to-end encryption. police may even be able to access encrypted messages in platforms such as Signal or Wickr. IMessage’s big advantage is that it’s built into every iPhone, so people don’t have to install a separate app to have secure communications. Apple's iPhone encryption is strong, but law enforcement agencies can still bypass it. Wickr is good for enterprise use, as it lets your business to create its own private network, with centrally-managed security policies for users. Unlike Signal, which uses your phone number, Wickr doesn’t require a phone number or email address to register. Wickr Me offers 1:1 chats as well as group chats, which is in line with the other apps here. However, as revealed last year, Confide was full of security holes. Its features include disappearing messages, screenshot-proof messages, and the ability to “un-send” a message as part of the Confide Plus subscription. It’s closed source, which is a big downside when it comes to privacy and security apps. App Store: Wire – Free ConfideĬonfide was the chat app famously used by people in President Trump’s administration. That means you can have a separate account for personal life and work life. A unique feature is Wire’s support for multiple accounts. Wire is also open source, and offers chat, voice and video calls, and file sharing. Wire is based in Europe and follows Swiss data protection laws, and its servers are located in Germany and Ireland. This means that if someone steals your encryption key, they can’t go back and decrypt past messages. Signal also uses something called forward secrecy. It has features like group chat, voice and video calls, file sharing, and disappearing messages. ![]() Endorsed by Edward Snowden, Signal is free and open source. Signal was one of the first private chat apps to enter the scene. You can get more information and an extensive FAQ on the Wickr webpage.There are plenty of private chat apps on the market, but are they all the same? We’ll take a look at five of them and see how they compare: Signal, Wire, Confide, Wickr Me, and iMessage. I can't really test the security of the app, but the people involved with the creation of the app and the names on Wickr's advisory board are impressive. Delivery was a bit slower than real time or using iMessage, but it was still prompt. Wickr claims the app is made with best-in-class security technology, so no two users will ever have the same encryption key and the key is destroyed upon use by the sender's phone. Metadata is not shared so time, location and any identifying tags are deleted. The app also allows you to attach videos or photos from your camera roll, or images that are taken directly using the app camera controls. Just like iMessage and most other messaging apps, there is no charge for the Wickr service the app is free, and messages are delivered over the internet at no cost. You can also set expirations on messages so they'll disappear after a pre-determined amount of time. Even better, the Wickr servers do not have the keys to decrypt your messages. Wickr says it can top them all with a free iOS app containing military-grade encryption (AES256, ECDH521, RSA4096 TLS). Wickr Me, a free messaging app best known for its end-to-end encrypted communications, will stop accepting new users after December 31, 2022, AWS Wickr announced. Apple has claimed iMessage is extremely secure, but that claim has been questioned. For quick communications, we have iMessage and a host of other messaging apps, each with varying degrees of security. ![]()
