Follow the steps for the sign-in method you are using. ### If You Are Not Receiving the Email OTP If you have chosen to sign in using an OTP sent to your email address: * Check your Spam or Junk folder for the OTP email. * Alternatively, sign in using your Zoho account password. * If you do not remember your password, click **Forgot Password?** on the sign-in page and reset it. Learn how to [reset your password](/invoice/kb/general/forgot-password.html). If you are still unable to sign in, write to [](mailto:support@zohoaccounts.com)[support@zohoaccounts.com](mailto:support@zohoaccounts.com). ### If You Are Not Receiving the MFA OTP on Your Mobile Number If you have enabled Multi-Factor Authentication and are not receiving the OTP via SMS: * Ensure that your registered mobile number has network coverage and can receive SMS messages. * Wait for a few minutes and request a new OTP. Use only the latest OTP you receive. * Try any other recovery options displayed on the verification screen. * If you downloaded backup verification codes when setting up MFA, use one of them to access your account. Learn how to use [backup verification codes](/invoice/help/settings/multi-factor-authentication.html#backup-codes). If you do not have another recovery option or backup verification codes, write to [](mailto:support@zohoaccounts.com)[support@zohoaccounts.com](mailto:support@zohoaccounts.com) from your registered email address.
