in the [keycloak document](https://www.keycloak.org/docs/latest/server_admin/#limit-token-audience), it mention the

> In a browser authentication flow, the browser session translates to `RootAuthenticationSession` while browser tabs translate to a collection of authentication sessions within the `RootAuthenticationSession`

> 

> The maximum number of authentication sessions per `RootAuthenticationSession` can be configured in `authenticationSessions` SPI by setting property `authSessionsLimit` . The default value is set to 300 authentication sessions per a `RootAuthenticationSession` .

can i simply interpret the above as: in a browser SSO session, a user can sso/login at most 300 clients ?

can anybody give a more explanation for that setting?

thank you.
