Google is trying to take control of my email

Thank you for the image.

This is a Security Alert to warn you that someone - in this case, you - has signed in using your details. It is not a request for permission. Since you signed in on your iPhone you can ‘ignore’ it.

Hello,

Start here:

Add an email account to your iPhone, iPad, or iPod touch - Apple Support

Good luck.

I assume you have already added your two email accounts to an email application such as Mail.

Where or how is Google asking you to grant them permission?

This email seems to indicate that your school email is backed by Google...
