How to change MFA number | FAQ - Zoho Accounts

How do I change the MFA number?

To change MFA number, you need to be signed in to your account. If you're locked out of your account:
  1. Contact your administrator to reset MFA in case you're an organization user.
  2. Contact in case you're not part of any organization.

Change existing MFA number

You may want to change your existing MFA number in the following scenarios:
  1. You no longer use your existing MFA number and want to switch to a new number.
  2. You have moved to a new location where your existing MFA number is not working.
  3. You have lost access to your existing MFA number and want to add a new number
Note: For users who registered after January 1, 2024, SMS-based OTP won't be provided as an MFA option. This is due to the susceptibilty of SMS-based OTP  to various security threats like phishing, SS7 and SIM swapping attacks.
