How to get away “google couldn’t verify it’s you” notification?

To prove that it’s you, you should do a verification using the following options:

1. You should have access to the mobile that has associated with the Gmail account.
2. If you already signed in to the device then it also can ask for verification for a lost password or any other reason
3. If you have turned on the two-step verification and you have the security passcode then it will be easy to recover the account.
