If you own an Echo device, such as the Echo Show or Echo Dot, you'll have access to a nifty feature known as Drop-In. This allows you to start a conversation with Alexa contacts or use the smart home gadget as an impromptu intercom.

Here’s what you need to know about the useful Drop In feature – along with how to disable it if you’re looking for some privacy.

Download the app

Step 1: First, ensure you have the Alexa app downloaded on your Android or iOS device (and that it is the latest version). You will need two different Echo devices for Drop In to work: With the app, you can drop in on other Echo devices, but you can’t receive a Drop In call via the app.

Step 2: Once you’ve downloaded and launched the app, you should be prompted to set up Alexa Calling and Messaging. If you aren’t, tap the speech bubble at the bottom of the screen to sign up and fill out your contact information.

Enable Drop In on devices

The Drop In feature might be turned off in the app, so you may have to opt in to use it.

In the Echo device settings, look for the section that says Communications, and select it. The Communications section will have a Drop In section. Make sure that Drop In is turned on. You can select it and choose between On, Off, and Only my household.

Step 1: Head to the icon at the bottom of the Alexa app that says Devices.

Step 2: In the devices menu, choose the device on which you want to enable the Drop In feature.

Step 3: With Drop In enabled on all your Echo devices, you should be able to initiate household drop-ins just by saying, “Alexa, drop in on,” and then saying the specific name of the Echo device. If this is all you want to do, then you’re good to go.

However, you can also enable drop-ins outside your house if you want to, and permitted contacts will be able to drop in on your Echo.
