How do I add a recovery phone number?

In case you forget your password or cannot sign in for some reason, adding a recovery phone number will let you get back your Zoho account. We strongly recommend you set up a recovery phone number. To add a recovery phone number:

In User Panel click My Zoho Account.
In the accounts page that opens, select My Profile Info -> Phone Numbers.
Click Add Phone button at the top right corner, type your phone number and click Add Phone.
A One-time password (OTP) will be sent to your phone. Enter the OTP at the given text box and click 'Verify my Mobile'.

Notes:

To secure your account, make sure the phone number you use for recovery is not accessed my multiple people.
You cannot use the same phone number for recovery option and for two factor authentication.
