How to find out how many devices are associated with our Gmail account

That Google is always up to date when it comes to security, I think few people can deny it. Continually you are updating Gmail security so that millions of users do not suffer security problems, identity theft, passwords theft ... The last service offered to us to always have controlled the devices with which we access or have accessed any of our accounts is the possibility of seeing that Devices have been connected to our account, where we can revoke the permissions that we have previously granted. The operation of this service is very similar to that of applications such as Twitter and Facebook, where in order to access from our devices we must give prior permission.

To access we just have to go to the Security tab and click on Devices and activity. Then all devices will be shown, whether they are mobile phones, tablets, smartphones, PC or Mac in which we have logged into our Gmail account during the last 28 days. If by chance you are not going to continue using the computer or device because it is no longer in your hands, you can revoke the permission so that it can be accessed again.

This section shows us the accesses to our account during the last 28 days and that are still valid. Below will be shown devices that have not connected in the last 28 days along with an exclamation point. It is very likely that if you usually restore the devices or devices that you normally use, the same device will appear several times with the date of the last connection. Ideally, to be able to have this list in conditions, the ideal would be that we were to withdraw the authorization to these old devices.
