Signal end-to-end encryption: the key to more secure communication All in all, open-source code is highly scrutinized and generally trusted to be secure. They’re also able to report bugs to Signal developers who can then fine-tune the app.
“Open source” means it gives security analysts around the world free rein to examine and test the app to determine whether it’s truly secure, private, and running as well as it could be. Signal also uses open-sourced code, which really takes the “more heads are better than one” mantra to heart. In fact, development is supported entirely by grants and donations.
