I want a kind of app which will help me manage my all accounts


I have some strict accounts and want some one tell me about an app which will help me manage my all logins at one app.

Because I want privacy and some strict logins so I can save my all accounts at one app.

Please guide me. If you couldn’t get what I want to convey. Please let me know in the comment boxes.

Thank you so much.

I want to elaborate a little more, For example, this is my site Tennis ball throwing machine for athlete and i have other banking apps and i have multiple more accounts like paypal or payoneer.
How I can connect all these in to one portal with strong security?
