 ===== Architecture =====
 The current proposed architecture is a Python Flask application with PostgreSQL as the backend database.
-===== Session management =====
-Sessions will be referenced by long-lived cookies (e.g. 30 days) that get refreshed on use. The session data itself will be stored in a Session table. The currently planned data includes:
-^ Column ^ Type ^ Description ^
-| id     | UUID | Session ID  |
-| secret | str  | Rotated session cookie secret |
-| member_id | FK | The member this session is for |
-| created | DateTime | When the session was first created |
-| last_active | DateTime | When the session was last used |
-| last_email_auth | Optional[DateTime] | When an email authentication was performed |
-| last_keyfob_auth | Optional[DateTime] | When a keyfob authentication was performed |
-| last_totp_auth | Optional[DateTime] | When a TOTP authentication was performed |
-| last_passkey_auth | Optional[DateTime] | When a passkey authentication was performed |
-==== Authentication Level ====
-The session's current authentication level will be calculated based on the fields in the Session table. The exact rules are still to be determined, however they will fit into the following levels:
-  - Plastic. The lowest authentication level when using a keyfob login.
-  - Bronze. Sessions that haven't authenticated in a while.
-  - Silver. Sessions that authenticated recently but didn't use 2fa.
-  - Gold. Sessions that authenticated recently with 2fa.
-In OpenID terminology this is called the ACR.
-===== Permissions model =====
-Permissions shall be granted through OAuth scopes or other custom claims. As these claims can sometimes be application specific, a general purpose approach is proposed using Members, Roles and ClaimSets with the following relationships:
-  * Many-to-many between Members and Roles
-  * One-to-many between Roles and ClaimSets
-A Role describes a high-level role a member has, for example "onboarding". A ClaimSet describes the specific OAuth claims associated with that role. The reason for separating ClaimSets from Roles is to be able to limit a ClaimSet to a single OAuth client without requiring a member to join multiple Roles if that Role involves multiple clients.
-An example ClaimSet for Grafana access to the "viewer" team may look like the following:
-<code>
-{
-    "scope": ["openid", "email"],
-    "groups": ["viewer"]
-}
-</code>
-This ClaimSet would be restricted to the Grafana OAuth client in order to avoid granting the "openid" scope to other clients and inadvertently giving access to them.
