When creating a Hostinger account, you associate an email address with it, which is used to log in to your hPanel.
If you no longer have access to that email address, or if you have activated two-factor authentication and lost access to your linked device, send a request to recovery@hostinger.com.
You can do so from any other email address. Only make sure to indicate the current email address associated with your Hostinger account in the message. Once we receive the inquiry, we will reply within 7 business days.
