Make a plan for your data. Google makes it easy to assign a person to your account or to automatically delete your data when you die.
Here's how:
Go to your Gmail account and click on your picture. Select Account. Next, click "Data and personalization."
Look for "Make a plan for your account" and click start.
You can make lots of choices in your plan, including people you wish to have your Google photos. You can decide when Google starts to worry that you have passed — after three months of inactivity is the default. But you can set it for whatever you want.
