How to use Disappearing Messages in Signal

If you’re a Signal messenger user, you can further improve the security and privacy of your Signal communications and messages by enabling and using the disappearing messages feature. Just as it sounds, disappearing messages causes Signal to automatically disappear and remove messages after a specified time period. Even better is that it’s customizable, so you can set disappearing messages to be enabled for specific contacts, and you can toggle the feature off and on at any time (as can the other person you’re communicating with).

For some quick background for the unfamiliar; Signal is a popular and highly regarded free secure messaging client that not only enhances communication privacy and security with end-to-end encryption, but is also popular because of it being cross-platform compatible, available for iPhone, iPad, Android, Windows, Mac OS, and Linux. That cross-platform availability makes it more versatile than iMessage, which while also encrypted, is limited to the Apple ecosystem. Signal requires a phone number to setup, but once you have it configured on an iPhone or Android you can then easily setup the client on a Mac, Windows PC, and other desktops too. And this might be obvious, but anyone you want to communicate with using Signal will need to have the Signal app on their device or computer as well.

Let’s walkthrough how to setup disappearing messages in Signal, including Signal messenger for iPhone, iPad, Android, Mac, Windows, and Linux:

Adjusting the Signal Disappearing Messages Time in Signal Mobile

After you have enabled Disappearing Messages for a particular contact in Signal, you can quickly adjust the Signal disappearing messages time by tapping the clock icon at any time.

So for example if you want to send a message that only lasts 5 seconds, you could quickly toggle that setting on to 5 seconds, send the message, wait for the recipient to receive it, then adjust the disappearing messages setting back to say an hour, 6 hours, 12 hours, or a week again.
