Free security checks you can do at home

Phone settings, messages you receive, and photos you share. Review how you and your family use them, one area at a time.

These checks focus on things you can do without extra spending.

What to check in six places

Look at what is currently shown, then decide whether to change a setting or habit. Menus and features vary by device and service.

Check
In settings, look for OS and app updates and a screen lock.
Where

In a service you use often, look at sign-in protection such as two-step verification and recovery email or phone.

Email and text messages

Check
Before opening a link, see whether you can check the claim through your usual official app or a bookmark saved earlier.

Your usual official app, in order history, delivery status, or billing history.

Photos and personal details

Check
Before sending or posting, check visible details, recipients, and the audience for the post or shared link.
Where
Photo information and sharing options, or Google Photos participants and link sharing.

Important data

Check
Find where important photos and documents are stored, whether there is a separate backup, and when it was last made.

Home Wi-Fi

Check
In the router settings or maker’s guidance, look for updates and see whether the administrator password is still the default.
Where
Find your router model, then open its maker’s update instructions.

Three roles for everyday security at home

Check before acting

Check the sender and contents before opening, entering, or sending.

Messages, photo and file sharing

Prepare a way back

Set up recovery before a loss or mistake happens.

Account recovery, backups, support contacts

Checking together as a family

Ask how the person usually uses the device or service, then look at one thing together. Explain any setting change before making it. Find the service’s official support contact before a problem happens.
