+## Authentication
+
+This section outlines the authentication requirements for the application. This section
+is **not** broken down by page, they are simple defined.
+
+#### Pages
+
+- [ ] **Register Page**
+    - [ ] Input form with required details: *name, email and password*
+    - [ ] *Password strength meter**
+    - [ ] User should be directed to the home page when account is created
+        - [ ] User will be logged in
+        - [ ] A notification will be provided to the user indicating success and redirection
+    - [ ] User should see error messages when validation issues occur
+        -  [ ] Email already in use
+        - [ ] Passwords do not match
+        - [ ] Server failure (this should never happen)
+
+- [ ] **Sign In Page**
+    - [ ] Input form with required details: *email, password and forgot password button*
+    - [ ] User should be directed to the home page after signing in
+        - [ ] A notification will be provided to the user indicating success and redirection
+    - [ ] User should see error messages when validation issues occur
+        - [ ] Invalid password
+        - [ ] Server failure (this should never happen)

+
+#### API Requirements
+
+- [ ] **Register Page**
+    - [ ] Create a new user in the database
+        - [ ] Password should be stored in the database as a hash
+    - [ ] Ensure that emails are not duplicated
+    - [ ] "Log user in" when account is created
+    - [ ] User should be redirected to the home page on success
+
+- [ ] **Sign In Page**
+     - [ ] Sign user in and return data to be stored in the session
+     - [ ] Validate password to the hash stored in the DB
+    - [ ] User should be redirected to the home page on success
+
+- [ ] **Session Management**
+     - [ ] *Uses cookies to store required data**
