Amazon has announced it is shutting down Wickr Me, the consumer version of its ultra-secure messaging app.

Amazon acquired Wickr in June 2021. Wickr is a messaging app that offers end-to-end encryption and does not require a phone number or other identifying information to register. Its security and privacy make it a popular option among government agencies, such as US Customs and Border Patrol (CBP), but also among criminals.

With mounting criticism over how Wickr is used, Amazon has decided to suspend new signups for Wickr Me and ultimately shut the service down altogether:

At Wickr, we’ve served a diverse set of customers that range from the boardroom to the battlefield. Since AWS acquired Wickr in 2021, we’ve listened closely to our customers to better understand their requirements for end-to-end encryption. After careful consideration, we will be concentrating Wickr’s focus on securing our business and public sector customers’ data and communications with AWS Wickr and Wickr Enterprise, and have decided to discontinue our consumer product, Wickr Me. As a result, we will not accept user registrations for Wickr Me after December 31, 2022, and will discontinue Wickr Me on December 31, 2023.
