This solution is for Zoho users who are facing issue while completing the Zoho API Connect step on SMS - magic portal (where the Zoho CRM Credentials are not accepted even if they are right)
--> This happens due to 2-factor authentication on Zoho
Log in to your Zoho CRM.
Click on the tools Icon (as shown in the image below).
Click on My Account
Click on Two Factor Authorization.
Click on Manage Application Specific Passwords.
Enter the Device (or) App Name as ‘SMS Magic’.
Enter your current Zoho password.
Click on Generate.
Once you click on Generate, you will see a new password generated.
Copy this password and save it. (we need to use this password to complete SMS Magic setup)
Goto www.sms-magic.in in a new tab.
Sign in using your sms magic credentials. (if you are already logged in, then logout and again log in)
Once you sign in, you will see the following page (check the following screenshot).
Here type in your Zoho username
And type in the password that you generated in step 1.
Click on Save.
