feat: Magic-link one-click UI authentication (no token in URL)#1516
Conversation
- Add MagicLinkStore with HMAC-SHA256 signed nonces and TTL - Implement JWT cookie authentication with HttpOnly, SameSite=Strict - Add magic-link consumption route (GET /?link=<nonce>) with 302 redirect - Extend authentication logic with cookie support and loopback bypass - Add 'praisonai gateway mint-link' CLI command - Update onboard process to generate and display magic links - Add rate limiting for magic-link endpoint (5 attempts/60s) - Include comprehensive unit and integration tests - Ensure backward compatibility with existing ?token= auth Tokens never appear in browser history, access logs, or referer headers. Magic links expire after 10 minutes and can only be used once.

Inline comments:
In `@src/praisonai/praisonai/cli/commands/gateway.py`:
- Around line 217-233: The gateway CLI's manual help in gateway_callback() is
missing the newly registered command gateway_mint_link; update the help text
shown by gateway_callback() to include a short description and usage example for
"mint-link" (mention TTL, host/port options), so the top-level "praisonai
gateway" help lists the new flow; modify the help string or command listing
logic inside gateway_callback() (referencing gateway_callback and
gateway_mint_link) to add a line like "mint-link Generate a one-time magic
link (options: --ttl, --host, --port)" and include an example similar to other
commands.
In `@src/praisonai/praisonai/cli/commands/mint_link.py`:
- Around line 29-33: The top-level import block in mint_link.py currently calls
sys.exit(1) when the optional MagicLinkStore import fails; instead, change this
to raise an exception so callers (like onboarding) can handle failure
gracefully. Replace the except ImportError: print(...); sys.exit(1) with raising
a clear exception (e.g., raise ImportError("Magic link functionality not
available") from e or raise RuntimeError(...)) so that mint_fresh_link and any
other importers can catch the error rather than having the module terminate the
process; keep the existing log message if desired but do not call sys.exit().
In `@src/praisonai/praisonai/cli/features/onboard.py`:
- Around line 636-644: The output still prints the authed info URL with a query
token (exposed via _info_url/_masked) even though the magic link says “no token
needed”; update the message construction in onboard.py (the block that composes
the Quick Access / Dashboard / Gateway endpoints strings using _magic_link_url,
_health_url, _info_url and _masked) to stop including the token in the printed
Info URL—display the plain /info endpoint (no ?token=...) and replace the inline
query example with a short header-based usage line for advanced users (e.g. "Use
header: Authorization: Bearer <token>" and note the token is stored in
~/.praisonai/.env as GATEWAY_AUTH_TOKEN), so the token is not shown in the
printed URL or browser-referrer.
In `@src/praisonai/praisonai/gateway/cookie_auth.py`:
- Around line 80-89: The code currently builds payload via {"iat":...,
"exp":..., **claims} and serializes with a comma-delimited string (payload_str)
which allows claim injection and lets callers override reserved keys; fix by
rejecting/raising if incoming claims contain reserved keys ("iat","exp"),
construct payload = {"iat":..., "exp":...} then extend it only with filtered
claims, serialize using JSON (json.dumps(payload, separators=(",", ":"),
sort_keys=True).encode("utf-8")) and pass that bytes value to signer.sign;
update the same pattern around payload/payload_str usage (including the similar
block at ~110-120) to ensure consistent JSON signing and preventing reserved-key
overrides.
In `@src/praisonai/praisonai/gateway/magic_link.py`:
- Around line 224-245: The mint method currently accepts ttl but does not
persist it, so update mint (and the created MagicLinkEntry structure used by
_load_entries/_cleanup_expired) to store either an explicit expires_at timestamp
or the ttl value alongside nonce, timestamp, and signature; set expires_at =
int_timestamp + ttl (fall back to self.default_ttl if ttl is None), persist that
field when writing entries in mint, and then modify consume and _cleanup_expired
to check that stored expires_at (or stored ttl combined with the entry
timestamp) is used for validity checks instead of self.default_ttl so per-link
TTLs are enforced during consume/list/cleanup operations.
- Around line 115-138: The _get_or_create_secret function can race when multiple
workers run first-time; change creation to be atomic by attempting an
exclusive-create/write and falling back to reading the file on collision: use
the secret_file path (Path object named secret_file) and perform an exclusive
create (e.g., open with O_CREAT|O_EXCL or Python 'x' mode or create a temp file
and os.replace) to write the generated secret; if exclusive create fails because
the file already exists, re-read secret_file and validate length before
returning; also after a successful write, re-read the file to verify what was
persisted and return that value to ensure all processes use the same secret.
- Around line 178-204: The _save_entries method currently swallows OSError and
silently fails, allowing mint() or consume() to report success without persisted
state; change _save_entries (in class handling magic links) to propagate
failures (either by removing the outer try/except so OSError from
temp_path.write_text, os.chmod, or os.replace bubbles up, or by returning a
boolean success flag) and update callers mint() and consume() to only return
success after _save_entries confirms persistence; ensure the logic around
temp_path.write_text, os.chmod(temp_path, 0o600), and os.replace(temp_path,
self.storage_path) is preserved and any caught errors are reported/raised to the
caller rather than ignored so minted links are stored and consumed flags are
durably persisted before signaling success.
- Around line 27-38: The fallback FileLock class creates an instance-level
threading.Lock which doesn't prevent concurrent access to the same file across
different MagicLinkStore instances; change the fallback to use a module-level
mapping from lock path to a single threading.Lock (e.g., a dict `_locks_by_path:
Dict[str, threading.Lock]`) and have FileLock.__init__(self, path) obtain the
shared lock from that map (creating it atomically if missing), and update both
places the fallback is defined/used so the lock is keyed by the path;
alternatively, if you need true multi-process safety and filelock is absent,
make persisted MagicLinkStore fail closed (raise on init) or make filelock a
required dependency for persisted stores.
In `@src/praisonai/praisonai/gateway/server.py`:
- Around line 290-298: The cookie auth manager is being created from environment
variables via create_auth_manager_from_env and validated after consuming
magic-link nonces, which can accidentally burn one-time links; instead
instantiate the cookie manager using self.config.auth_token (e.g., construct the
same auth manager but passing self.config.auth_token) and run its
extract_token_from_cookies/is_token_valid checks before calling
_magic_store.consume(nonce) or before any magic-link flow; update the
`_check_auth` logic (the block creating auth_manager and token_from_cookie) and
the corresponding duplicate block around lines for 540-559 to use
self.config.auth_token and validate the cookie first, only proceeding to
magic-link consumption when cookie auth is absent/invalid.
- Around line 302-306: The current loopback bypass (checking client_host from
request.client for '127.0.0.1'/'::1'/'localhost') must be made opt-in: add and
check an explicit dev config flag (e.g., ALLOW_LOOPBACK_BYPASS or
DEV_LOOPBACK_BYPASS from your app config/env) before returning None, and
additionally require that the connection appears direct by rejecting the bypass
if proxy headers like X-Forwarded-For or Via are present (inspect
request.headers) so the bypass only applies when the flag is true AND there are
no proxy headers; update the code around the client_host check to reference the
new config flag and the header checks.
In `@src/praisonai/tests/integration/gateway/test_magic_link_flow.py`:
- Around line 122-144: The test_gateway_magic_link_integration currently
exercises MagicLinkStore and CookieAuthManager directly but does not exercise
the actual GET /?link= gateway route; update the test to perform an HTTP request
against the route handler (either by using Starlette's TestClient against the
app or by invoking the route handler factory directly) so you validate
Set-Cookie, 302 redirect target, nonce consumption, and auth_manager
configuration end-to-end; specifically, in test_gateway_magic_link_integration
replace the direct calls to magic_store.mint()/consume() and
auth_manager.create_session()/verify_session() with a TestClient GET to
"/?link=<token>" (or call the handler returned by the route factory) and assert
response.status_code, response.headers["set-cookie"],
response.headers["location"], and that magic_store.consume was invoked and
session was created via CookieAuthManager.
- Around line 38-47: The magic_store fixture currently allows
MagicLinkStore(storage_path=...) to call _get_or_create_secret() which touches
the real PRAISONAI_HOME; to fix, ensure the fixture isolates secret state by
either setting the PRAISONAI_HOME environment variable to temp_storage for the
duration of the magic_store fixture or by constructing MagicLinkStore with an
explicit secret_key from a new fixture (e.g., secret_key) and pass that into
MagicLinkStore; update the magic_store fixture (and auth_manager if reused) to
use the temp_storage-bound secret so _get_or_create_secret() does not write to
the host home directory.
In `@src/praisonai/tests/unit/gateway/test_magic_link.py`:
- Around line 284-288: The test currently allows 0o644 which weakens the
intended 0o600 restriction; update the assertion around
storage_path/stat_info/permissions so on POSIX platforms you assert permissions
== 0o600, and only skip or branch for non-POSIX (e.g., os.name == 'nt' or
platform.system() == 'Windows') using pytest.skip or a conditional check; ensure
you reference storage_path/stat_info/permissions and perform the platform check
before asserting so Windows/other platforms that cannot represent POSIX perms do
not fail the strict assertion.
- Around line 217-221: The test currently converts the nonce timestamp to float
and passes that into _verify_nonce_signature which expects the integer timestamp
used by mint(); update the test to parse/convert the timestamp portion as an int
(use int(parts[1]) or cast before building the signed string) so that the
verification in store._verify_nonce_signature(raw_nonce, int_timestamp,
signature) uses the same "{nonce}:{int_timestamp}" value that mint() signed.
- Around line 22-27: The test test_init_default currently lets MagicLinkStore
use the real home which reads/writes ~/.praisonai/.magic-secret; update the test
to isolate filesystem by either setting the PRAISONAI_HOME env var to a
temporary directory (e.g., via monkeypatch.setenv) before constructing
MagicLinkStore or by constructing MagicLinkStore with explicit test-only
parameters (pass a temp secret_key and a storage_path created from the pytest
tmp_path fixture) so MagicLinkStore() does not touch the real user home; update
assertions to use the instance created this way.

Stop advertising the deprecated token URL beside the magic link.
The new panel says “no token needed,” but the same output still prints Info (authed) with ?token=.... That preserves the browser-history/referrer/log exposure this feature is trying to remove.

Use structured serialization and reserve iat/exp.
The comma-delimited payload lets claim values inject additional claims during parsing, e.g. a user_id containing ,exp:9999999999 overwrites the parsed expiration. Also, **claims can directly override iat/exp.
Reject reserved claim keys and sign JSON instead of a custom delimiter format.

When filelock is unavailable, each MagicLinkStore instance gets its own threading.Lock, so two stores in the same process can still concurrently read/write the same JSON file. That breaks the one-time-consumption guarantee in the fallback path.
At minimum, use a module-level lock keyed by lock path; for true multi-worker safety, fail closed or make filelock a required dependency for persisted magic links.

fallback FileLock class creates an instance-level threading.Lock which doesn't
prevent concurrent access to the same file across different MagicLinkStore
instances; change the fallback to use a module-level mapping from lock path to a
single threading.Lock (e.g., a dict `_locks_by_path: Dict[str, threading.Lock]`)
and have FileLock.__init__(self, path) obtain the shared lock from that map
(creating it atomically if missing), and update both places the fallback is
defined/used so the lock is keyed by the path; alternatively, if you need true
multi-process safety and filelock is absent, make persisted MagicLinkStore fail
closed (raise on init) or make filelock a required dependency for persisted
stores.

Keep the integration fixture’s secret state inside temp_storage.
MagicLinkStore(storage_path=...) still calls _get_or_create_secret() and touches the real ~/.praisonai/.magic-secret. Patch PRAISONAI_HOME to temp_storage or pass a fixture secret_key to avoid cross-test and host-state coupling.

Exercise the actual GET /?link= route here.
This test is named as gateway route integration, but it only calls MagicLinkStore and CookieAuthManager directly. It will not catch route bugs such as missing Set-Cookie, wrong 302 target, nonce consumption order, or auth-manager configuration mismatches.
Use TestClient against the Starlette app/route, or extract the handler factory so the route can be tested directly.

Isolate default-store tests from the real user home.
MagicLinkStore() writes/reads ~/.praisonai/.magic-secret by default, so this unit test can mutate developer or CI host state. Patch PRAISONAI_HOME to a temp directory or pass a test secret_key/storage_path.

The test test_init_default currently lets MagicLinkStore use the real home which
reads/writes ~/.praisonai/.magic-secret; update the test to isolate filesystem
by either setting the PRAISONAI_HOME env var to a temporary directory (e.g., via
monkeypatch.setenv) before constructing MagicLinkStore or by constructing
MagicLinkStore with explicit test-only parameters (pass a temp secret_key and a
storage_path created from the pytest tmp_path fixture) so MagicLinkStore() does
not touch the real user home; update assertions to use the instance created this
way.

Use the integer timestamp from the nonce when verifying HMAC.
mint() signs "{nonce}:{int_timestamp}", but this test converts the timestamp to float, producing "{nonce}:123.0" and causing the expected signature check to fail.

The test currently converts the nonce timestamp to float and passes that into

update the test to parse/convert the timestamp portion as an int (use

Assert the restrictive permission promised by the feature.
Allowing 0o644 would pass a world-readable magic-link registry, which contradicts the 0600 security goal. On POSIX, assert 0o600; skip or branch only for platforms that cannot represent it.

The test currently allows 0o644 which weakens the intended 0o600 restriction;
update the assertion around storage_path/stat_info/permissions so on POSIX
platforms you assert permissions == 0o600, and only skip or branch for non-POSIX
(e.g., os.name == 'nt' or platform.system() == 'Windows') using pytest.skip or a
conditional check; ensure you reference storage_path/stat_info/permissions and
perform the platform check before asserting so Windows/other platforms that
cannot represent POSIX perms do not fail the strict assertion.
