What happened? 

OneAuth becomes the gateway to access your account if you haven't configured any other MFA modes, such as SMS-based OTP, Time-based OTP, or YubiKey. Losing access to OneAuth after configuring it as a primary MFA mode for your Zoho account will result in losing access to your account.

How to resolve this issue? 

You can recover access to your account on your own if you have set up any one of the following sign in options for your account.
Note:  If you haven't configured any of the above sign in options, write to our support team at support@zohoaccounts.com. We will help you in recovering your Zoho account.
