I cannot find the twilio dashboard for the SSID

After logging in to your Twilio account locate your name in the top right of the page. Click it, select ‘Account’, and then on this page, under Auth tokens , will be your Account SID and Auth Token.
Use Account SID as SSID and Auth Token as AUTH_TOKEN.

Hi @Amrita_dey ,

Do let me know in case you need any other information.

After you’ll login and the dashboard will open.
Please scroll down a bit and you will be able to see your Account SSID , Auth_num and your twilio number.
