Does not authenticate on firebase

I had problems with a project in which I was authenticating with firebace I was using email and google as authentication, I started another project, I also created another project in firebase and I used the same codes as before if they worked for this new application and I also put the necessary compiles and it does not authenticate me, if I want to register an email it will not let me and if login with google send me a toast that I made error and in the firebase does not save that login.
