I've set up a custom provider for my Firebase project where I use signInWithCustomToken
to authenticate a user on Firebase.
If a user authenticates with a built-in Firebase provider like Google, Google's icon shows up under the "Providers" column.
Can I show an icon for my custom provider?
It's not currently possible to configure your own icon for user accounts created by a custom provider. It does sound reasonable though, so I recommend filing a feature request for it.
