Mobile devs who added Apple Sign In, what conversion changes?

Haven’t done anything with Apple sign in, but I worked with a lot of other providers before. If you have multiple options, users might forget what service they used. This becomes an even bigger problem if the paid for a service with a different provider and can’t find their purchase. If you do use something like this, only having one provider (only Apple) makes things less confusing.

On one consumer iOS app with email and apple sign in as the two available options, 34% opt for apple, 66% for email. No meaningful change in conversion rate, but this generally isn't an issue 90%+. The prior arrangement wasn't just email, though, it was email or phone sign up, so take what you will.

I’m not a dev but a consumer in this question and I’d just say a service or site that has Sign In with Apple and Apple Pay available on the web is and instant use on my end. I will continue to vote with my paltry wallet for these technologies to take off even more, especially Sign In with Apple.

I don’t want to give my actual email out. I like the relay aspect. And it should make logging in and user management and single sign on and all that much easier no?

I hate technologies like this. Not because I don't think they at least contribute some benefit to end users.

I see it as oblivious executives trying to monopolize whatever they think they can monopolize.

The future is in yubikey-style authentication.

Apple Sign in to be mandatory by June 30th for certainuse cases (source: Apple WWDC update email from a few days back).

Along with a number of other enforcements.

I'm looking at adding this into a new app I'm developing, and assumed I'd do a default apple login on IOS and google login on Android (with the option to go see more login options on other devices)

Anybody think this is a bad idea for some reason?

I’m about to embark on a new iOS built with SwiftUI. What backend would you recommend for authentication (server side) when using Sign In with Apple? Do you all use Firebase?

I will never use the same service to sign into multiple things. It's a single point of failure. If Apple ever decides to close your account you're S.O.L.

I made the mistake once, had an account closed, got royally screwed. It wasn't Apple but it doesn't matter. I learned my lesson. Don't tie things together.

I don't follow that for everything but for anything important I do as well as anything involving money.
