Unified service session management. Is it possible to make a single firewall management service?

Question

Nginx

Good afternoon!
I have a question of the following nature,
there are implementations:
a certain permission service for services due to activation links.
My idea is step by step:
1. That is, a client comes from an unknown ip,
2. and he is asked to enter an e-mail, where an activation key is sent to him for 1 hour of working with the organization's services.
3. After activation, access to the organization's services is opened
3.1. That when you exit the browser and re-request (on the server), it passes by the service control check service immediately, for example, to gita.
Are there such solutions?
