Using 'regular' login/registration AND api token based login/registration - using Jetstream?

Hi, I've been using Jetstream(intertia+vue) - to create a really cool and robust admin for a website.

I am passing the data produced in the admin etc via API's to a seperate frontend, and all has gone great so far and loving jetstream. So I would have www.siteurl.com which is a self contained Nuxt web app, then admin.siteurl.com where admin can login and manage site etc...

..however, I am not wondering how I can have Auth features for the API based frontent/web app using the same database, ie I am creating an ecommerce website, the user needs to be able to register/login etc... I am wondering if/how this is possible with this setup? or if there is a solution to make this work?

any help massively appreciated - as come along way with it, dont want this to be an impossible stumbling block
