I have to build a portal for my institute which will act as a job portal for the institute. Companies should be able to post their job/intern openings on the portal. For that to happen, one prime condition is that HRs should login only with their work profiles and thus their personal accounts(gmail,etc.) should be restricted. I have seen some similar questions where we had to whitelist a particular domain and restrict all others but this might not be feasible in this case, as whitelisting all the work domains doesn't seem practical. Is there a built-in solution for this? My Tech Stack is: NextJS for the frontend. For the backend part, I am thinking of either NodeJS+mongoDB OR Sanity.io depending on a more feasible solution for the above problem statement...
