Can I provide two account details on the Amazon Fire TV Stick?

Have the stick on jmd other run, as well as netflix, disney + etc. Would it be feasible if I now want to let Prime Video go from my account? So it's just their data on it. But will the bank details be asked again when you register? And if I give my information there, will it be taken over so that I can't watch netflix and stuff like that? I really hope you know what I mean, it's difficult to explain.

You can log in to the stick with your data. And if you then e.g. Then go to the netflix app and register again for netflix. It doesn't matter whether the data is the same as for the stick. It is independent of each other!
