New user cannot login to Zoho CRM

New user cannot login to Zoho CRM

We recently created a login for our new user with access to Zoho CRM and Zoho Campaigns. The user is unable to login to the system as the OTP generated was sent to a mobile no that is not in the system. Kindly suggest a way to change this phone number to the correct one.

Thanks for your support!

Sujani.
