Possible to make multiple guard with Fortify without Jetstream?

You can use Foritfy as a separate package. Jetstream is just a wrapper around the API of Fortify. However, you're free to do this yourself as well ;)

You can find the documentation here: https://github.com/laravel/fortify#using-fortify-for-headless-authentication

Try https://laravel.com/docs/8.x/authentication#adding-custom-guards

I would not use separate guards for this.

admins, teachers and students are all users - treat them as such. Control what they can do through authorization.

With your current plan, what if a teacher is also an admin?

Thank for your response ;)

Is it the same to create multiple guards in laravel 7 to be implemented in laravel 8? thanks

sir you mean want one table for everything?

Yes, one table is the better approach for the authentication system. You should use a role-based authorization system for different users.

And yes, multiple guards work the same in Laravel 8 as in Laravel 7. As discussed above, you don't need that ;)

sir how to handle different needed for example

teacher has NIK, Name and student has NIM, Name

for approach one table?
