To access the 3CX Web Client, just follow these few easy steps:
1. Find Your Login Details #
Open your email inbox and look for an email with the subject “Welcome to 3CX” sent by the system or your IT administrator. Inside that email you’ll find:
- Web Client URL (example:
https://3cx.id) - Extension Number (this acts as your username)
- Password
2. How to Log In #
- Click the Web Client URL from the email using a browser such as Google Chrome or Microsoft Edge.
- Enter your Extension Number in the username field.
- Enter your Password.
- Click Login.
💡 Extra Tip: Install It as an App (PWA) #
For extra convenience so you don’t have to open a browser every time, you can install it directly on your computer:
- After successfully logging into the Web Client, look at the Address Bar at the top of your browser.
- Click the Download/Install icon (usually a monitor with a down arrow, or a “+” symbol).
- Click the Install button.
- The 3CX app will now appear on your computer’s desktop just like a regular application.
If you’ve lost your welcome email, you can ask your company’s IT administrator to resend the welcome email so you get the correct access link.
Do you also need a guide for connecting the 3CX app on your phone (Android/iOS) using a QR code?
