Passwords are where team chat rollouts usually stall. Half the staff forget them in the first week, someone writes the shared one on a whiteboard, and IT or the office manager becomes a full-time reset desk. C Chat removes that step entirely, the same way consumer messengers like WhatsApp do: your phone number or email address is your login.
What passwordless sign up does in C Chat
Passwordless sign up means you prove who you are with a short code sent to something you already have, instead of a secret you have to remember. In C Chat that is either your phone (code by SMS) or your inbox (code by email). If you want the technical background, read our glossary entries on passwordless authentication and the one-time passcode (OTP).
Once you’re in, you set up a simple profile:
- Name — how teammates see you in groups and direct messages.
- @username (optional) — lets people find you without your phone number.
- Photo — helps new staff recognize who is who.
How to sign up step by step
- Go to getcchat.com/c in any browser.
- Choose phone or email and enter it.
- Type the code you receive by SMS or email.
- Add your name, and if you like an @username and a photo.
- Create a team, or open the invitation you received to join an existing one.
For people joining an existing team, the invitation usually arrives first. Admins can send it by WhatsApp, SMS or email, or share an invite link or QR code. The person taps it, signs up with their code and lands in the right team.
Real scenarios from business teams
A cleaning company with rotating staff. New cleaners start every month and many have never used a work app. Asking them to invent a password adds friction on day one. With a phone number and a code, they are in the client building’s group before their first shift.
An office team moving off personal chats. Staff already use their phone numbers on personal apps, so signing up with an SMS code feels familiar. That familiarity is a big part of what makes it practical to migrate work chats from WhatsApp.
Contractors and clients. A plumber invited to one project group or a client invited to their site group signs up the same way, with no account setup call needed.
Privacy, permissions and limits
Your phone number or email is used to sign you in and send codes. If you prefer colleagues not to see your number, sign up with email or set an @username. Everything you send is protected by TLS in transit and AES-256 at rest with per-organization keys; the security overview explains how that works and who can read what.
A few honest limits:
| Topic | What C Chat does |
|---|---|
| Single sign-on | Not offered — see what SSO is |
| Separate 2FA settings | Not offered — sign-in is by one-time code (what 2FA is) |
| Free plan | Up to 50 members per team, 5 teams per account |
If your company requires SSO for every tool, C Chat may not fit that policy today. For many frontline and small teams, code-based sign-in is the simpler choice. More detail on the risks and protections is in passwordless sign-in security.
Tips for admins
- Send invites the way people already communicate. For field staff, a WhatsApp or SMS invite is opened faster than an email.
- Ask people to use the number or email they keep. A personal number that changes every few months creates support work later.
- Encourage @usernames for staff who don’t want to share their phone number with clients or guests.
- Plan offboarding too. When someone leaves, remove them from the team so they lose access to its groups.
The team onboarding guide has a full rollout plan, and onboarding new employees covers day-one setup.

Frequently asked questions
How do I sign up for C Chat without a password?
Open getcchat.com/c, enter your phone number or email address and type the one-time code C Chat sends you by SMS or email. Then add your name, and optionally an @username and a photo.
Is passwordless login less secure than a password?
Not necessarily. A one-time code can't be reused, and there is no password for people to write on a sticky note or repeat across sites. The weak point moves to the phone number or inbox, so protect those with a SIM PIN and a strong email login.
Can I sign up with email if I don't want to give my phone number?
Yes. You can sign up with an email address and receive the code by email instead of SMS. You can also set an @username so colleagues can find you without seeing your number.
Does C Chat support single sign-on (SSO) or separate 2FA settings?
No. C Chat does not offer SSO or separate two-factor settings. Access is based on one-time codes sent to your phone or email, which keeps sign-up simple for frontline teams.
What happens if I lose access to my phone number?
If you signed up with a phone number and lose it, contact support@cguardpro.com. Keeping a SIM PIN with your carrier also reduces the risk of someone taking over your number.
