I am using fire base email/password authentication in my android app in java. When I sign up with any email_id even if it does not exist, it does sign-up successful, only restriction is this that this id should contain @gmail.com at end. Kindly guide me why this happening and how to restrict to allow sign-up for only that id’s that at actually email_id’s. And also for valid email it say “sign-up failed”
Thanks
