What is the best platform for user login management?

Question

I am looking for a viable solution for managing users and login across web, mobile apps, Roku and Apple TV. I cant seem to find a good solution and would prefer not to put resources into building one out.

Update/Clarification: I am looking for a solution for my users to login, not my own personal login. Example, user signs up on my website but wants to login to mobile app.

OAuth is fantastic. If we weren't using Firebase to build our apps, we'd be using OAuth for all of our authentication needs.

If you're willing to pay for some higher-level features, I highly recommend Auth0. (Could be free if you have < 7,000 users). Check out Passwordless to make sign-in flows on mobile and especially on TVs that are frictionless.

Robust solution to manage your user identities and help them easily login via oAuth providers (Google, Facebook).

Also, see Auth0 recommended by Kunal Bhatia.
