do you need my updated Ebay password or can you simply bid on my behalf?

Hello Graham,
Thank you for your question about changing your eBay password. We do not use or store your eBay password, so you should be ok. To be safe, go to BidSlammer Preferences and follow the link to authorize. That is good for 18 months.
Thank you for taking the time to write in. Please let us know if we can provide any other assistance.
