!!! Overview
[{$pagename}] is an [entity] which is trusted to be your [Custodian] of your [Digital Identity].


Because it’s painful to create new identities from scratch, [Identity Providers|Identity Provider (IDP)] like [Facebook], [Google], and [Amazon] have created systems that let you use them as a trusted [{$pagename}] so you can establish a login at other sites based on your identity on their site. However, the more you take advantage of these systems for providing what are called [Federated Identities|Federated Identity] ,the more of your online identity is owned by a company, and not by you. For [example], if [Facebook] decides to terminate your account, you lose your access to and your [Digital Identity] at sites that you have asked to rely on your [Facebook] login. It also means that these [{$pagename}]s knows just that much more about you and the sites you visit.

These [Identity Providers|Identity Provider (IDP)] do this as they use the [data] they collect about you and your actions to provide [Advertising] which is how they make [Money] off by providing you this service.


!! [Self-Sovereign Identity]
[Self-Sovereign Identity] only changes this slightly.

[{$pagename}] are __still required in all [Self-Sovereign Identity]__ systems [{$applicationname}] has encountered. 

Most [Self-Sovereign Identity] are based a [Distributed Ledger Technology] (like [Blockchain]) but which is a [Permissioned System] that only allows certain [Agents] access to the actual [Blockchain]. Additionally, due to the complexity of securely managing and storing your [Digital Identity], most people will not host a "[Digital Wallet]" themselves which implies a [{$pagename}] will be used by most [Natural Persons].

[{$pagename}]s is able to give a [key] back when it’s lost. Ideally, we [SHOULD] be able to choose which [{$pagename}] to use and switch as often as wanted. Most if not all of the [Self-Sovereign Identity] systems do not currently allow.
We also need different [{$pagename}] for holding identity [data] and holding a [key] in escrow, to ensure segregation of responsibilities, and to reduce [risk] of exposure.

[{$pagename}]s are not going to be a [Provider of services] for your [Digital Identity] and not harvesting the [data], they will need to be compensated for this effort, or like the [National Identification Number] ([National ID]) by [government], have it be a role assigned to them and [funded|Money] some other way.

There are several other fundamental challenges with using [{$pagename}]s:
* First is access to a user’s [Private Key], which must be high-[friction]. It [SHOULD NOT] be possible for a rogue employee of an [{$pagename}] to get access to your [Private Key]. But it must be possible, with your involvement, to recover the [Private Key]. High [friction] and convenience do not go hand-in-hand.
* How do you prove who you are… when you cannot prove who you are? The [Key Recovery] must handle the situation that you have forgotten the key entirely and have no possessions that can help.
The third challenge is building a key recovery system in such a way that it is secure, cost-efficient and usable. No system will be 100% secure, but due to the importance of keeping [Private Keys] private, a high level of [security] is a must.
* Will [personal data] become more [private|Privacy] under [SSI] or more [government] [observable|Observer] if one person’s data is all in one place?
* [Self-Sovereign Identity] has a high degree of [Complexity]
