## ADDED Requirements
|
|
|
|
### Requirement: Passkey registration
|
|
The Journal SHALL allow new users to register using a passkey (WebAuthn) when the browser supports it. No password is required.
|
|
|
|
#### Scenario: Successful passkey registration
|
|
- **WHEN** a user enters an email and username and creates a passkey via the browser prompt
|
|
- **THEN** a new user account is created, the passkey credential is stored, and the user is logged in
|
|
|
|
#### Scenario: Duplicate email
|
|
- **WHEN** a user submits an email that is already registered
|
|
- **THEN** the system displays an error indicating the email is already in use
|
|
|
|
#### Scenario: Duplicate username
|
|
- **WHEN** a user submits a username that is already taken
|
|
- **THEN** the system displays an error indicating the username is not available
|
|
|
|
### Requirement: Magic link registration (fallback)
|
|
The Journal SHALL allow new users to register via magic link when the browser does not support passkeys. The user can add a passkey later from a supported browser.
|
|
|
|
#### Scenario: Register without passkey support
|
|
- **WHEN** a user's browser does not support WebAuthn
|
|
- **THEN** the registration page shows a "Register with Magic Link" button instead of the passkey button
|
|
|
|
#### Scenario: Successful magic link registration
|
|
- **WHEN** a user submits email and username via magic link registration
|
|
- **THEN** a new user account is created without a credential, a verification email is sent, and the user is redirected to verify their email
|
|
|
|
#### Scenario: Magic link verify redirects to add-passkey
|
|
- **WHEN** a user clicks the verification link from magic link registration
|
|
- **THEN** they are logged in and redirected to the home page with the add-passkey prompt
|
|
|
|
### Requirement: Passkey login
|
|
The Journal SHALL allow returning users to log in using a stored passkey when the browser supports WebAuthn.
|
|
|
|
#### Scenario: Successful passkey login
|
|
- **WHEN** a user clicks "Sign in" and selects a passkey from the browser prompt
|
|
- **THEN** the user is authenticated and redirected to their activity feed
|
|
|
|
#### Scenario: No passkey available
|
|
- **WHEN** a user has no passkey on the current device
|
|
- **THEN** the system offers magic link login as a fallback
|
|
|
|
#### Scenario: Browser without WebAuthn support
|
|
- **WHEN** a user's browser does not support WebAuthn
|
|
- **THEN** the login page shows only the magic link option with no passkey button
|
|
|
|
### Requirement: Magic link login (fallback)
|
|
The Journal SHALL allow users to log in via a magic link sent to their email. This serves as a fallback for devices without passkey support or for logging in on a new device.
|
|
|
|
#### Scenario: Request magic link
|
|
- **WHEN** a user enters their email and clicks "Send magic link"
|
|
- **THEN** an email with a single-use login link is sent to their address
|
|
|
|
#### Scenario: Valid magic link
|
|
- **WHEN** a user clicks a valid, non-expired magic link
|
|
- **THEN** the user is logged in and the link is invalidated
|
|
|
|
#### Scenario: Expired magic link
|
|
- **WHEN** a user clicks a magic link older than 15 minutes
|
|
- **THEN** the system displays an error and prompts them to request a new link
|
|
|
|
#### Scenario: Rate limiting
|
|
- **WHEN** a user requests more than 5 magic links in 10 minutes
|
|
- **THEN** subsequent requests are rejected with a rate limit message
|
|
|
|
### Requirement: Add passkey from new device
|
|
The Journal SHALL allow logged-in users to register additional passkeys for new devices.
|
|
|
|
#### Scenario: Add passkey after magic link login
|
|
- **WHEN** a user logs in via magic link on a device that supports WebAuthn
|
|
- **THEN** the system prompts them to register a passkey for that device
|
|
|
|
#### Scenario: Add passkey prompt on unsupported browser
|
|
- **WHEN** a user logs in via magic link on a device that does not support WebAuthn
|
|
- **THEN** the system shows the add-passkey prompt with a message that the browser does not support passkeys
|
|
|
|
### Requirement: Passkey status display
|
|
The Journal home page SHALL show the user how many passkeys they have registered.
|
|
|
|
#### Scenario: User with passkeys
|
|
- **WHEN** a logged-in user visits the home page and has one or more passkeys
|
|
- **THEN** the page displays the passkey count (e.g., "2 passkeys registered")
|
|
|
|
### Requirement: User profile page
|
|
Each user SHALL have a public profile page displaying their username and routes.
|
|
|
|
#### Scenario: View own profile
|
|
- **WHEN** a logged-in user navigates to their profile
|
|
- **THEN** they see their username, bio, and a list of their routes
|
|
|
|
#### Scenario: View other user's profile
|
|
- **WHEN** a user navigates to another user's profile URL
|
|
- **THEN** they see that user's username, bio, and public routes
|
|
|
|
### Requirement: Federated identity structure
|
|
User accounts SHALL follow the federated identity pattern (`@user@instance`) to prepare for ActivityPub federation in Phase 2.
|
|
|
|
#### Scenario: Username format
|
|
- **WHEN** a user registers with username "alice" on trails.cool
|
|
- **THEN** their full identity is stored as `@alice@trails.cool`
|
|
|
|
### Requirement: Session management
|
|
The Journal SHALL maintain authenticated sessions using secure HTTP-only cookies.
|
|
|
|
#### Scenario: Session persistence
|
|
- **WHEN** a logged-in user closes and reopens their browser
|
|
- **THEN** they remain logged in if the session has not expired
|
|
|
|
#### Scenario: Logout
|
|
- **WHEN** a user clicks "Log out"
|
|
- **THEN** their session is invalidated and they are redirected to the login page
|
|
|
|
### Requirement: No passwords
|
|
The Journal SHALL NOT support password-based authentication. All authentication is via passkeys or magic links.
|
|
|
|
#### Scenario: No password field
|
|
- **WHEN** a user views the registration or login page
|
|
- **THEN** there is no password field
|
|
|
|
### Requirement: Magic link login
|
|
The magic link login flow SHALL deliver the link via email in production instead of logging to console.
|
|
|
|
#### Scenario: Production email delivery
|
|
- **WHEN** a user requests a magic link in production
|
|
- **THEN** the link is emailed to the user (not just logged to console)
|
|
|
|
#### Scenario: Dev mode unchanged
|
|
- **WHEN** a user requests a magic link in development
|
|
- **THEN** the link is returned directly for auto-redirect (existing behavior preserved)
