# Using SMS or voice authentication with PingID

You need to register or 'pair' your mobile device with your account so that you can receive a one-time passcode (OTP) to your device by SMS or voice call, and use it to authenticate securely with PingID.

Pairing a device creates a trust between your device and your account so that you can use your device to authenticate during the sign-on process. After you have paired your device, each time you sign on to your account or application, you receive a one-time passcode (OTP) through SMS or voice call with which to authenticate.

You can use SMS or voice calls to access your account using a Web browser, to access your company's VPN, or to access a Windows login or Mac login machine.

   |   | To support voice calls using phone numbers with extensions, enter the phone number followed by a comma and the extension number. Examples include:- The phone number +12025550123 with the extension 2992 is entered as +12025550123,2992.

   - The extension can include the # or \* characters. For example: +12025550123,#2992 or +12025550123,2992#.

   - If there is more than one extension, then a comma should separate the extension and the nested extension. For example: +12025550123,#2992,#2991.

   - Each comma generates a 2-second pause. After the call is answered, the extension is dialed after two seconds. If a pause is required for longer than 2 seconds, add an additional comma for each additional 2-second pause. For example, three commas for a 6-second pause before the nested extension: +12025550123,#2992,,,#2991. |

   #### Result:

   PingID sends a one-time passcode (OTP) to your mobile through SMS or voice call.

   ![A screen capture of the SMS verification window, requesting that you enter the SMS passcode that you received.](_images/hig1634044091955.png)

4. In the **Authentication** window, enter the OTP. Click **Verify**.

   #### Result:

   When successfully verified, the green **Authenticated** message appears, and you are automatically signed on to your account or app.

### Next steps

The next time you sign on to your organization dock or application:

1. PingID sends an OTP to your mobile device.

2. In the **Authentication** window, enter the OTP.

3. Click **Sign On** to complete the authentication.

     |   | Phone numbers with extensions are supported for voice calls where the phone number is followed by a comma and the extension number. Examples include:- The phone number +12025550123 with the extension 2992 is entered as +12025550123,2992.

     - The extension can include the # or \* characters. For example: +12025550123, #2992 or +12025550123,2992#.
