Undefined index: password in EloquentUserProvider laravel

Undefined index error occurred when you are using custom login with custom columns default #laravel use password column eg: you have defined column just like entity_password  in database and you have passed in $credential array for auth()->guard();

This is wrong for login auth

public function LoginAuth_Method(){
	$credentials = ['entity_email'=>'customlaravel_login@sdtuts.com','entity_password'=>'ThePassword!!'];
	$studentAuth = auth()->guard('mycustomGaurd');
	$studentAuth->attempt($credentials);
}

Just you have to change key from entity_password to password and define it custom entity_password into CustomLoginModel

class CustomLoginModel extends Authenticatable{
	public function getAuthPassword(){
            return $this->entity_password;
	}
}
