+# Access
+
+{{#template ../templates/implemented.md}}
+
+Access is the primary system for restricting access to locations and equipment on the station.
+Additionally, it serves as the baseline mechanical difference for most [jobs](jobs.md).
+
+```admonish note "All Access"
+Ephemeral Space deliberately eschews the common mechanic of "All Access" that many servers have.
+
+This is because being able to congregate all potential access onto a single ID not only is extremely powerful, but creates a boring situation where getting AA is the undisputed best option for breaching.
+It carries no cost compared to having normal access, cannot be reasonably detected, and ultimately is just uninteresting.
+By at least forcing multiple job-preset IDs to be held, players at least must make a choice between which specific accesses they want and how much inventory space they will sacrifice for it.
+```
+
+The prevalence of a particular access level across the crew creates a gradient of traffic.
+Areas like maintenance are essentially free for anyone to enter, with common department accesses like engineering being more traveled, and more secure accesses like Bridge being fairly difficult to enter.
+This variance in how easily an area can be reached is important for the placement of objectives and important equipment.
+
+Lockers and crates that are restricted via access can serve as an additional level of difficulty.
+Since, unlike airlocks, they cannot be bypassed via hacking, items secured inside locked containers are much harder to acquire and can even be moved around without necessarily being compromised.
+
+## Personal Lockers
+
+Personal lockers (differentiated by their blue lights) serve as an additional level of access restriction that goes beyond simple access levels.
+Since it's still fairly easy for a role like the station administrator or captain to acquire an ID with any job's access via a computer, basic access is primarily a mechanism only for non-command roles.
+This is often an issue when factoring in the power of these roles, as they can easily create IDs and loot valuable equipment out of lockers.
+
+This issue is addressed through personal lockers, which are tied to a _specific_ **ID card** rather than an access level.
+A Dr. Jimmy's personal locker doesn't care about medical access, rather it specifically wants Dr. Jimmy's ID.
+Since this is not something that can be replicated or obtained outside of stealing it from Dr. Jimmy, it creates a much more secure location for storing goods that is more resilient to brazen searches or overzealous command.
+
+An important detail about this system is also that, until the personal locker is assigned, it's unable to opened without the use of some tool or weapon.
+This means that, in a situation where you have a single security officer and leftover gear in lockers, you're _unable_ to simply hand out gear to whoever wants it, both increasing the likelihood that a late-joining role will be able to grab their gear while also preventing surplus meant for higher player counts from distorting balance.
+
+## Emergency Access
+
+Emergency access is an auxiliary access override available only for airlocks.
+By entering an airlock's 3-digit access code into the **emergency access terminal**, the airlock can be toggled into emergency access mode, bypassing all access checks.
+The terminal is kept inside of bridge, meaning that it's generally restricted only to command members (although breaking in is far from impossible).
+
+An intentional complication with this process is the fact that you cannot see an airlock's access code from the terminal itself.
+Since you have to be next to the airlock, this means the terminal takes much more of a supportive role than a proactive breaching one.
+Trying to open 3 sequential doors with the terminal is extremely hard, so you likely need to communicate with someone at those doors in order to open them quickly.
+At the same time, those doors are now open to everyone: if you don't move quickly or have someone secure it for you, whatever you're after could easily be stolen while you try to make your way over.
+
+The goal isn't for emergency access to be a premium way of breaking into areas, but rather to have an option for actual urgent entry into a location that is otherwise too hard to get into.
