Laravel can be used without a database and / or with a database not created by migrations , although your blog will surely need publications, tags, categories or similar things that will require a database to be stored.
Now, if you want to manipulate only logic in laravel and have an external database, you can consume a web service in php and store the data in another server (although of course, in that case it would be better to consume it directly from the client's side). / p>
Now, if you just want to create an account you can do it in the enviroment or .env file that is at the root of our project. For that, you create a variable that is called user=miusuario
and password=password
.
Once you have created your username and password, you can access them using the function env("nombre_clave")
for example env("user")
to obtain the value.
The advantage of leaving the user in the .env file is that you can call it from anywhere and when you want to modify it will be in a centralized place and you will not have to search file by file where you have left the username.
If you want security you can directly put a hash in the password and then validate with the hash functions that laravel gives us.
