Signal is easier to use well when both people agree to it and know how they will find each other. Depending on your boundaries, you might share a username, link, QR code or phone number. Check which detail is being shared and what visibility you want before writing. Open with one recognisable subject, ask before a voice or video call and remember that disappearing messages can still be copied or photographed.
Agree how you will connect
Ask whether Signal suits them. If it does, decide between a username, link, QR code or number. A username can begin contact without sharing a phone number, but phone visibility and discoverability are separate settings. A username is not a permanent public profile or a directory of strangers.
Check a QR code belongs to the person you mean before scanning it, and keep it out of public groups and social feeds. Share only the identifier required for this conversation.
Use a context anchor
Start with how you know each other: โI am Ana from Luisโs ceramics class.โ If the contact is unexpected, ask for context before continuing. A name or photo on screen cannot by itself prove who is using the account; rely on shared context and choose what to reveal.
A screenshot you send to an AI tool also exposes any names, numbers or unrelated photos in it. Crop what is unnecessary and share only content you are allowed to share.
Keep the conversation manageable
Pick one thread after the greeting: a recommendation, a shared project or a question you left open. Answer one point before adding another and allow the other person to set the pace. Thoughtful replies do not have to be immediate or enormous.
If someone sounds uncomfortable, check what they would prefer. Do not describe disappearing messages as a reason to send intimate material: the recipient can still capture, copy or photograph it.
Ask before moving on
Before a voice or video call, ask whether a short call would suit them or whether they would rather keep writing. Give a length and accept no. If you arrange to meet, agree a public place and time in the channel you both chose; a call is not a test.
You can finish politely: โThanks for the chat; I am going to stop here today.โ If there is no reply, do not use another username to force an answer.
Message examples
Agreeing the route
Would you be happy to use Signal? I can share my username; I would rather keep my mobile number private for now.
It seeks agreement and makes the desired phone boundary explicit.
A recognisable opener
Hi, it is Dani from the photography workshop. I kept thinking about the camera you recommended.
It says who is writing and continues a real shared subject rather than asking for unexplained attention.
Before a call
Would a ten-minute voice call this evening suit you, or should we keep messaging? Either works for me.
It checks comfort, sets a manageable frame and keeps text as an equal option.
