A report in The Verge says that following a few days, the secret key will be required to open an email. These passwords will be given to clients through an instant message. There will likewise be an email sent to you. After that time the email will be naturally erased. Google needs to make Gmail more well known among clients through these means.
Note that Google will present some more advantages for Gmail clients. These incorporate different applications utilizing Gmail, disconnected Gmail, and so on.
