Google may implement a feature to give users a temporary email address soon called Shielded Email.
Google may allow users to have a temporary email address to use on third parties instead of your actual one. Anything that the alias email address receives will be sent to your actual email’s inbox. This feature is called Shielded Email.
If users wish to remove the temporary email address, it can simply be removed in the settings too.
According to Android Authority, users can have more than one Shielded Email address. There is no news when this feature will be released to the public just yet.
