Signal's New Username Feature Fixes Their Biggest Onboarding Problem

I Tested Signal Usernames for a Week—Here's What Happened

I've used Signal for personal messaging for two years. Never for work. The idea of giving out my personal phone number to colleagues felt wrong. When Signal launched usernames last week, I immediately set one up. I've been using it for professional contacts for 7 days. Here are my real-world results.

Why I Couldn't Use Signal Professionally Before

My situation: I work with multiple clients and contractors. I need to communicate securely, but I'm not giving my personal cell number to everyone I work with.

My previous setup was messy:

• Personal contacts: Signal (secure, but they have my number)
• Professional contacts: WhatsApp (insecure, but separates personal/work)
• Anonymous sources: Telegram (don't trust it, but no phone number required)

I wanted Signal for everything, but the phone number requirement was a dealbreaker. Giving clients my personal number meant they could call me anytime. Boundaries matter.

Setting Up My Username

The setup took 2 minutes. I opened Signal, went to Settings → Profile, and created a username. I picked something professional but not my real name—@davidtech.

Important: Signal warned me that usernames are not discoverable. There's no public directory. If I want someone to message me, I have to give them the username directly.

I tested sharing it three ways:

• Via email: "Message me on Signal @davidtech"
• Via LinkedIn DM: Gave the username to a potential client
• On my business card: Printed @davidtech on the back

Real-World Testing Results

Test 1: New client conversation. I gave a prospective client my Signal username instead of my number. They messaged me within an hour. The conversation worked exactly like normal Signal—end-to-end encrypted, disappearing messages available. They never saw my phone number. Success.

Test 2: Group chat with contractors. I created a group for a project with 4 contractors. I added them by username instead of phone number. Worked perfectly. Nobody could see anyone else's phone number unless they were already contacts.

Test 3: The limitation test. I tried to find a colleague's username by guessing. Couldn't do it. There's no search, no directory. You have to know the exact username. This is good for privacy, bad if you lose someone's username.

What Actually Works

After a week, here's what's working for me:

Professional separation. I can now use Signal for work without giving out my personal number. This was the main goal, and it works.

Group privacy. In group chats, participants only see usernames unless they're already contacts. This is huge—I don't want every contractor seeing every other contractor's phone number.

Easy to share. "@davidtech on Signal" is easier to share than reading out a phone number.

What's Still Missing

It's not perfect. Three limitations are annoying:

No discoverability. If I meet someone at a conference and want to stay in touch, I have to spell out my username. No QR codes, no "nearby" feature. I wish Signal had a temporary QR code I could show people.

No multiple identities. I get one username per account. I can't have separate personal and professional usernames. I have to choose: am I @davidtech for everyone, or do I stick with my number for personal contacts?

Still need a phone number. The username doesn't replace the phone number requirement for signup. I still had to verify with my real number. This is a barrier for sources who need complete anonymity.

My Verdict

I'm keeping the username. I've already moved two active client conversations from WhatsApp to Signal. The professional separation matters more than the minor limitations.

If you've avoided Signal because you didn't want to give out your personal number, usernames solve that problem. Create a username, put it on your business card, and start using the most secure messaging app for work.

One caveat: only one username per account. Choose carefully. I went with something professional because I decided to use it for work contacts exclusively.
