Authentication of two users into 1 browser session at the same time.
I have a requirement for a system I am building that the authentication be made for two users on 1 session at a time. The use case would be two partners signing a mortgage. So, partner1 logs into the session with a login and a password and then there is a section to add another user, partner2, who logs in and then the authentication is now good for two signers of that mortgage. The prerequisite is that both have already created profiles on the system such that they have logins and passwords.
1. Does anyone know of a system or application that does this?
2. Any tips on how to handle this?
Platform is django and angular1.
