Hi @Debs3,
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
To be able to help you out, I need to know which kind of passwords you want to delete. Could you elaborate a little bit more in where you want to delete passwords?
You can delete passwords saved in Chrome for example by going in to Chrome > Pressing the three dots in the top right > Settings > Passwords > Press the password you want to delete > Press the trashcan in the top.
Let me know if there is any other kind of passwords you want to delete.
