I'm creating a user registration panel in firebase with email and password through an application on React-Native, then in the registration act, wanted to see if the entered email is valid. As far as I know,
auth/weak-password
This is a small password ... but in the case of an invalid e-mail inserted?
Good! There are some messages related to user / email validation, the main ones being:
auth / invalid-email The value provided for the e-mail user property is invalid. Must be a string email address
auth / user-not-found There is no existing user record corresponding to the provided identifier.
auth / email-already-exists The email provided is already in use by another user. Each user must have an exclusive email address.
