‘Signal’ is a buzzword these days
after WhatsApp’s announcement of their latest privacy policy. It is seeing a
massive surge of users converting from WhatsApp,
as users want to denounce WhatsApp’s latest privacy policy, a shift that also
received a big boost when Tesla head Elon
Musk tweeted, “Use Signal.”

So if you’re switching to a privacy-focused messaging application, here’re 5 tricks that you need to know.

Setting Up a Screen Lock

Signal has a Screen Locking
feature, so you have to access your phone by a PIN or by a biometrical lock to
open the App even though your phone is unlocked. Therefore, no one can see your
texts, even though you had to hand over your phone to someone for some reason.

Go to Settings > Privacy >
Toggle Screen Lock on to set up your screen lock.

Turning Off Joining
Notification

Many people are joining Signal
now, so if your contacts join, your phone will start beeping like a fire alarm.
A great feature is that you can immediately deactivate all these alerts in one
step. So, you’ll enjoy using the App without being overwhelmed by unwanted
messages.

Go to Settings > Notifications
> Toggle Contact Joined Signal off, to Turning Off Joining Notification.

Blurring Faces in Images

You won’t want to send images of
people’s faces on them if you are worried about anonymity unless you have
obtained their permission. The alternative is to edit pictures manually, which
is tedious and time-consuming. But you have checked the signals—The picture
transmission alternative provides an automated face blurring feature, and other
parts of the screen can also be manually flattened, perfect for sending an
identification document, for example.

Tap the + sign > Tap on a
picture to send > Tap on the Blur button (which looks like a circle with
black and white tiles inside) > Toggle Blur faces. You can draw anywhere
on-screen with your finger to blur additional information.

Sending Disappearing Messages

WhatsApp has lately had messages
that have expired, but this is a long aspect of Signal. They are timely
messages which will then be discarded to keep the conversations confidential.

Open a chat, then enter the menu
by tapping on the person’s name > Toggle Disappearing Messages > Slide
the timer to set how long the message will last to send disappearing messages.

Setting How Many Times An Attachment Can Be Seen

A disappearing chat sets a time
limit for a message, but the other party has to have access within that
duration. The other person couldn’t see something if you put up to anything
like 5 seconds unless they talk actively with you. The attachment limits are a
very different way of privately sending messages. You may send an image or
video with this setting that is only available once, and once the attachment is
locked, it will vanish. So others will see it only once days or weeks after you
have sent it.

Tap the + sign > Tap on a
picture to send > Tap on the Infinity icon in the bottom left corner to set
how many times an attachment can be seen
