Wickr has published their crypto library as open source but the rest of the code is not open source.

Messages are not synced across all your devices as with most other messaging services. You can have multiple devices connected to one account, but messages will only go to the specific targeted device. Messages are bound to both your account and a specific device. In other words, messages may never get delivered if the recipient doesn’t log into Wickr frequently enough. If a message or attachment is still sitting on a server awaiting delivery when its time is up, it is deleted from the server as well. Once their time is up, they are permanently deleted from both the sending and receiving devices. That means they only exist for a certain amount of time.

All messages and attachments are ephemeral.

File, photo, video, voice message sharing.

Here are some key features to consider when deciding whether Wickr Me is right for you. There are also disposable email services you can use for this purpose.

Note: You can boost your privacy when registering for Wickr Pro Basic by anonymously signing up for a secure email service that you only use for your Wickr registration. However, if giving Wickr an email address would be acceptable in your particular circumstances, check out the additional features of Wickr Pro Basic, covered at the end of this review. I’m concentrating on Wickr Me in this review. On the positive side, Wickr Pro Basic has several features that Wickr Me does not.

While this supports password resets and verification of ownership for Wickr Pro accounts, it also eliminates the anonymity of Wickr Me. Wickr Pro requires you to use an email address as your username. Even if you link a phone number in Wickr Me that data is encrypted and cannot be read by the company.

The company has no way to identify the owner of a Wickr Me account because they have no access to any of your personal information. A Wickr Me account belongs to whoever has the correct credentials to log into it. Wickr Me distinguishes between users based on their anonymous username. Depending on your use case and threat model, you may want to consider using Wickr Pro Basic (the free tier of Pro) instead of Wickr Me. Wickr Pro and Wickr Me both run off the same secure code base, and there is a free version of Wickr Pro available.

Code is publicly visible on GitHub, but not open sourceīefore I take you deeper into the guts of Wickr Me, we need to talk about the differences between Wickr Me and Wickr Pro.

Does not log IP Addresses or Unique Device ID.

All user content is forensically wiped from the device after it expires.

Encryption algorithms: AES 256, ECDH521, and RSA 4096, with Perfect Forward Secrecy (PFS).

Client-side end-to-end (E2E) encryption.

I’ll also give you a short rundown of the rest of the Wickr product line, including Wickr RAM, the military muscle of the family. This kind of app is our focus here at Restore Privacy. In this Wickr review, I’m going to focus on Wickr Me, the free, anonymous personal version of the product. We recently reviewed Signal, so its time to find out what makes Wickr special. If Wickr and Signal are good enough for the 82nd Airborne to use in combat, it seems likely that they are good enough for you and me as well. “These are the two apps recommended by our leadership, as they are encrypted and free for download and use,” Foote said. Richard Foote, a spokesman for the 1st Brigade Combat Team, told Military Times. “All official communication on government cell phones within TF Devil has been recommended to use Signal or Wickr encrypted messaging apps,” Maj. According to Major Richard Foote, a spokesman for the 1st Brigade Combat Team (as quoted in Military Times), That was the situation faced by the soldiers of the 82nd Airborne’s Task Force Devil after deploying to an undisclosed location in the Middle East. And I would be willing to wager that few reasons are stronger than defending your communications against adversaries in the Middle East. And because Amazon is a global multinational company based in the United States, this also puts Wickr (and Wickr users) under US jurisdiction, and all the privacy implications that go with it.Įveryone has their own reasons for wanting to use a secure messaging service - but some reasons are stronger than others. Given the new ownership, you may want to consider some alternative secure messaging apps here.
