Hello Newbie! đź‘‹
Welcome to the community! Samsung Pass doesn't allow exporting passwords to a compatible format like a CSV file and you're correct that you'll need to manually copy and paste your passwords from Samsung Pass into new items in 1Password.
I see that you also reached out in an existing thread to see if the community has any tips on how to efficiently migrate your items, I suggest continuing the conversation there and I'll close this thread so that we avoid having the same conversation in two places at once.
