We support 2 login mechanisms outlined below.
The user can login via Metafi SDK with the supported SSO mechanisms. We currently support Google SSO login, and Passwordless email login - and we are working on adding more login methods.
If your game already has its own login mechanism implemented, you can still use the Metafi SDK by making use of this option.
You can choose to authenticate a user using any method of your choice, and pass in a unique UUID to the Metafi SDK, which will be associated with the user wallet permanently.
Both mechanisms employ a Passwordless Login Flow. This enables a better UX for the user, without compromising on security.
