How to do it:

Signal was built to protect you. It has asserted in court filings that the company can only access two pieces of information: when you created your account, and when you last connected to Signal. They can’t turn over your chat logs if they want to.

Don’t think you have anything to protect? Consider the things that were clearly protected just a few years ago and aren’t now. Traveling for reproductive care, being a legal non-citizen, and civil disobedience are just a few of the once-safe things that are being increasingly criminalized. If none of this applies to you, join Signal anyway: normalizing use protects everyone.

You can get started by simply installing it and connecting with other friends who use it. To learn more, check out this useful EFF.ORG manual.
