I've used your link to sign in with eBay but it's still not 100% clear to me that my eBay password is correct with Bidslammer so my active item will correctly be bid on using Bidslammer. I haven't used this for years and my password was changed several years ago. How do I verify this? I can't find the answer to this question in 'preferences' as stated.

Hello Debra,
Thank you for your question about your eBay password. We do not require it. We use authorization that you give to us through eBay. You can update it in BidSlammer Preferences under "Authorization Token."
Please let us know if you have any other questions, or require other assistance. We are happy to help.
