Login Cache?

Hi, I use another plugin that has a front-end login form. I noticed when I tried to login as another user, it wouldn’t work until I flushed redis. Then I was able to login, so I assume the login issue was a cache issue.

Do I need to exclude these login pages from the cache? If so, might there a list of other recommended pages that need to be excluded also or is there a setting for cases like these I should be using?

Thanks!
