Signal is a top choice for messaging, renowned for its commitment to privacy and security. Many users, including myself, have uncovered a variety of hidden features that enhance the messaging experience. Here are ten essential tips to help you leverage Signal to its fullest potential.
Conceal Your Phone Number
Signal allows you to use the app without exposing your phone number. While registration requires a phone number to deter spam, you can conceal it from other users. Simply access your profile, navigate to Settings, then select Privacy > Phone Number > Nobody. This setting ensures your number remains private.
Enhance Security with Registration Lock
To bolster your account's security, enable the "Registration Lock." This feature prevents unauthorized access to your Signal account on new devices without a PIN. If your SIM card is compromised, this lock acts as a safeguard. Activate it via Signal settings > Account.
Implement Screen Security
Signal's "Screen Security" feature blocks screenshots on Windows 11, protecting your messages from being captured without consent. For mobile users, enable Hide Screen in App Switcher on iPhone or Screen Security on Android to keep your chats discreet when switching apps.
Activate Screen Lock for Privacy
Screen Lock adds an extra layer of protection by requiring biometric authentication to access the app. This feature can be activated through Signal settings > Privacy > Screen Lock.
Customize Notification Profiles
With notification profiles, you can silence alerts from specific contacts during designated times, such as after work hours. Set this up by accessing Notifications > Notification profiles > Set up in the desktop app.
Utilize Disappearing Messages
Signal offers a "Disappearing Messages" feature that automatically deletes texts after a specified duration. This can be set for all chats or tailored to specific conversations through Signal settings > Privacy > Disappearing Messages.
Disable Stories Feature
If you prefer not to use the Stories feature, Signal allows you to disable it entirely. Navigate to Signal settings > Stories to turn it off.
Send Messages in Spoiler Format
Similar to iMessage's Invisible Ink, Signal's "Spoiler" formatting hides text until tapped. This is perfect for sharing spoilers about books or movies. Highlight the text, then select Format > Spoiler.
Relay Calls for Enhanced Privacy
To protect your IP address during calls, enable the option to relay calls through Signal's servers under Signal settings > Privacy > Advanced > Always Relay Calls. While this may slightly affect call quality, it significantly boosts your privacy.
Verify Safety Number for Secure Messaging
To confirm you're communicating with the correct contact, use the "Verify Safety Number" feature. This ensures that your chat remains secure and encrypted. You can view and verify safety numbers directly in your chat settings.
These features not only enhance the user experience but also fortify privacy and security, setting a standard for secure communication in the digital age.
