you can have ACL with only number replace and add, rather removing all ACL.
which type of ACL allows you to open port only after someone has successfully logged into router?
required more information and example of the use case - since this can be achieved in different ways.

All standard, extended, and Named ACLs allow for removing a single entry without removing the entire ACL; Long time ago, like pre-IOS 12.2 or around that time, standard ACL could not be edited such way. New IOS fixed that issue by applying numbering to ACL entries.
If you look at category like traditional ACL (old standard acl) vs Named acl vs Numbered acl (extended and new standard acls), then "old" traditional could not be edited (at least the easy way).
There are other ACL categorizes: Role-based, Time-based, reflexive ACLs, and dynamic ACL
will attach source link once i lookup my notes
