Replace login error snack bar

When the user tries to sign in and they don't have an account I get this error in the snack bar:

I definitely don't want that to show up to the user. I tried adding a conditional statement to the Firebase Login action but it doesn't give me a response to work with. There also doesn't seem to be a way to stop this snack bar from happening. Thoughts on how to approach this.

Hopefully I'm missing something obvious; otherwise, how is there not basic auth functionality?
