Your Google Account - Staying safe
Google Play does not allow anonymous access. A valid Google Account is required for every operation, even for downloading free apps. You are strongly advised to register a fresh account exclusively for using with Raccoon.
Nowadays, Google may ask you for a telephone number when registering a new account. This is a temporary anti spam measure applied to whole IP address ranges from which a suspicious amount of accounts were registered recently. If you don't feel comfortable with giving Google your telephone number (and you shouldn't), you'll have to simply sit it out (usually takes a day or two).
