How do you send a secret key or password to another team member? You can’t just hand someone a sticky note!
That’s why we recommend downloading and using the Signal app. Signal has end-to-end encryption and has been vetted by some of the top security minds.
We use Signal when sharing passwords, birthdates, files containing confidential materials and more. Further, anytime there is a security incident involving one of our clients, we recommend switching communications to Signal.
The app is free to download and use. Check it out, here.
