Concurrent OIDC logins for a single user

I’m using OIDC (/authorize endpoint) to authenticate users for my web applications (client id). Is there a limit for the same user to authenticate concurrently? In other words, if I want to give multiple people the credentials to “UserA”, how many “UserA” authentications can be used concurrently.

As far as I’m aware there’s no limit given the nature of the session/token/browser relationship, but it might be worth testing for!
