Add recovery mail id in gmail without login an account

A clever question!

Unfortunately, it's not possible to add a recovery mail ID in Gmail without logging into the account. The recovery mail ID is a security feature that is tied to the account, and it requires the account owner to log in and configure it.

When you set up a recovery mail ID, you're essentially telling Google that if you ever forget your password or lose access to your account, they can send a verification email to this alternate email address to help you regain access.

To add a recovery mail ID in Gmail, you'll need to log in to your account and follow these steps:

1. Go to the Google Account settings page.
2. Click on the "Security" tab.
3. Scroll down to the "Recovery email" section.
4. Click on the "Add a recovery email" button.
5. Enter the alternate email address you want to use as your recovery mail ID.
6. Click "Save" to save the changes.

If you're unable to log in to your account and need to add a recovery mail ID, you may want to consider using a password manager to help you recover your password.
