Google Titan on gmail

I am a school principal and our IT Dept is going to start having us use Google Titan keys for our school email. We are a GSuite customer.

I have a personal Gmail and a school Gmail account. Right now I tend to use the iPhone built in app for mail in calendar, but I do use the Google apps as well.

Does anyone have any experience using this enhanced security for Gmail or the actual Titan security key? I have always used 2FA on my personal Gmail account and on any other account that it is available for. Our GSuite accounts are managed by our IT department and they said our security for us.

Any thoughts or experience on how this will affect my iPhone experience?
