In case you have to change your eBay account password, you need to ensure to authorize Adspert for access again. In order to do so, follow these steps after you have updated your eBay account password:
On the Adspert Dashboard, go to the account settings by clicking on your profile icon in the top right corner and then clicking on “Adspert Account Settings”
Go to the “Manage Accounts” tab
On the right-hand side of your listed eBay account, click on the three dots under “Actions” and then “Change account access”
You will then be taken through the account connection flow during which you will be able to enter your updated eBay account password.
