Amazon Seller Account and Amazon Buyer Account - Same email address / same address

Hi All,

Need some suggestions from seniors and experienced.

I opened a buyer account for general buying for general items home/ kids etc. 10 years back.

Last year I opened a Professional Seller account and later changed the entity to Limited company,
The email to log in to both the buyer and seller accounts is the same.

I have stopped using my buyer account and my daughter opened a buyer account, and now she has left for University.

I have a query, Is it OK to use my buyer account (the same email address I use to login into my seller account or ask my wife to open a buyer account in her name)

I do not want to do something wrong and in the end, get my seller account restricted or penalised.

Suggestions will be highly appreciated.

Thanks in advance
