To start, open the eBay app on your smartphone or tablet, then select the menu icon found in the top-left corner.

Scroll down and tap “Settings.”

Choose the “Signing In” option.

Select “2-Step Verification.”

There are two options on the next page: “Set up 2-step verification” and “Use the eBay app.” Tapping either option takes you to the same page.

When you navigate this screen, you’ll be taken to a login page for either your fingerprint or the standard login page. Log in using whichever way is appropriate for you, choose your verification method of phone or email address, and then tap “Verify.”

Depending on which option you chose, eBay will either send you a text message or email containing a six-digit code. Enter the security code and select “Verify” to complete the process.

A success message will be displayed on-screen.

From now on, when you sign in to the eBay website, a notification will be sent to your eBay app. Tap “Approve” to access the website.
