Check who can get into your Gmail inbox in about two minutes

Google is asking Gmail users to run its Security Checkup, a free tool that reviews who (or what) has access to your account. Google says it takes about two minutes and three quick steps.

The reason to bother is simple. Your email often holds the logins for your bank and your online shopping. An old app or device that still has access to your inbox is an open door you may have forgotten about. The checkup helps you spot it.

Who it affects

Anyone who uses Gmail or a Google account, including people who rely on it for work or small business email. Google's message does not describe a specific attack or breach. It reads as a routine reminder to look over your own account.

What to do

The steps are in the alert box above. Google also points to a Gmail Help Center guide on protecting your account. It covers phishing, which means fake messages meant to trick you, and how to deal with unwanted senders.

Google's post does not say what prompted the reminder. It also does not spell out what each of the three steps covers, so expect the tool itself to explain them as you go. If you see an app, device or person you do not recognize, that is the thing to remove.
