Is there a way to set a password strength for Firebase?

Question

 const connect = auth.createUserWithEmailAndPassword(email,pass).catch(function(error){

          if(error.code === 'auth/weak-password'){
          errmsg.style.display = 'block';
          errmsg.style.opacity = '1';
          errmsg.innerHTML= 'The password is too weak.';
      }

With the default setting, the requirement for password is 6 characters (letter/number). Is there a way to change this (Ex. require password to be letter-number combined)>

Answer 1

The password strength of Firebase Authentication's email+password authentication is not configurable. If you want full control over the requirements, you can consider implementing your own provider on top of Firebase Authentication.
