Apple ID with a @gmail.com domain

Hi MMV59,

It's perfectly fine to use an @gmail.com email address as your Apple ID. As mentioned in the article with steps on creating an Apple ID you can use your current email address or get a free iCloud email address. Find that information below and in the article here: How to create a new Apple ID - Apple Support

"Create your Apple ID when you set up your device

1. Tap "Forgot password or don't have an Apple ID?"
2. Tap Create a Free Apple ID.
3. 
4. Select your birthday and enter your name. Tap Next.
5. Tap "Use your current email address," or tap "Get a free iCloud email address."
6. Follow the onscreen steps to verify your email address, create a strong password, set your device region, and set up two-factor authentication. If you choose to skip this step, you'll be prompted to do this later in Settings."
