Signal was founded in 2014 by Moxie Marlinspike, a well-known security researcher and entrepreneur, and Brian Acton, a co-founder of WhatsApp. The Signal Foundation, a non-profit organization, was established in 2018 to support the development and maintenance of the Signal app. The Signal Foundation is funded through donations and grants, and its mission is to promote privacy and security online.
Signal is a cross-platform encrypted messaging app that is developed by the Signal Foundation, a non-profit organization. The app allows users to send text messages, voice calls, video calls, and media files securely, with end-to-end encryption to protect the privacy of communication. Signal is available on a variety of platforms, including Android, iOS, and desktop computers.
One of the key features of Signal is its strong focus on privacy and security. The app uses state-of-the-art encryption techniques to ensure that messages and calls cannot be intercepted by third parties. It also includes a number of other security features, such as the ability to set a timer for messages to automatically delete after a certain amount of time, and the option to enable two-factor authentication for added security.
Signal has gained a reputation as a secure and private alternative to other messaging apps, and it is often recommended by security experts and privacy advocates. In addition to its messaging features, the app also includes a range of other tools, such as the ability to create groups, share location information, and send reactions to messages.
