The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
- Add VerifyPassword method to hide the bcrypt implementation details when authboss consumer code wants to verify the password out of band.
- ClientStateResponseWriter now supports the http.Hijacker interface if the underlying ResponseWriter does (thanks @tobias-kuendig)
- DelAllSession is a new method called both by Expire and Logout (in addition to still calling DelKnownSession etc. as they do now) to ensure that conforming implementations of ClientStateReadWriter's delete all keys in the session.
- Config.Storage.SessionWhitelistKeys has been added in order to allow users to persist session variables past logout/expire.
- Fix bug where user's expiration time did not start until their first request after login.
- Fix bug where expired users could perform one request past their expiration
- Fix bug with missing imports (thanks @frederikhors)
- Fix bug with inverted remember me checkbox logic
- Fix validation not happening when user commences recovery
- Deprecated DelKnownSession for DelAllSession. DelAllSession should be implemented by existing ClientStateReadWriters in order to prevent session values from leaking to a different user post-logout/expire.
- Add e-mail confirmation before 2fa setup feature
- Add config value TwoFactorEmailAuthRequired
- Add a more flexible way of adding behaviors and requirements to authboss.Middleware. This API is at authboss.Middleware2 temporarily until we can make a breaking change.
- Fix a bug where GET /login would panic when no FormValueRedirect is provided. (thanks @rarguelloF)
- Fix a bug where lowercase password requirements in the default rules implementation were not being checked correctly (thanks @rarguelloF)
- Fix a bug in remember where a user would get half-authed even though they were logged in depending on middleware ordering.
- Fix a bug where if you were using lock/remember modules with 2fa they would fail since the events didn't contain the current user in the context as the auth module delivers them.
- Fix a bug with 2fa where a locked account could get a double response
- Deprecate the config field ConfirmMethod in favor of MailRouteMethod. See documentation for these config fields to understand how to use them now.
- Deprecate Middleware/MountedMiddleware for Middleware2 and MountedMiddleware2 as these new APIs are more flexible. When v3 hits (Mounted)Middleware2 will become just (Mounted)Middleware.
- Deprecate RoutesRedirectOnUnauthed in favor of ResponseOnUnauthed
- Fix a bug with the 2fa code where a client that failed to log in to a user account got SessionTOTPPendingPID set to that user's pid. That user's pid was used as lookup for verify() method in totp/sms methods before current user was looked at meaning the logged in user could remove 2fa from the other user's account because of the lookup order.
- Add Config option to defaults.HTTPRedirector to allow it to coerce redirect response codes to http.StatusOK to help make more regular APIs.
- Add Config option for MailRoot. This is a URL that overrides the typical URL building using Root/MountPath that recover and confirm do to enable creating mail links to a different location than where the API is hosted.
- Add a configuration option that allows confirm to change the method type it expects since in an API setting a GET is strange as there is body details.
- defaults.HTTPRedirector now always responds with a "status": "success" when responding to an API unless there's a failure.
- defaults.JSONRenderer now renders a "status": "success" or "status": "failure" based on the presence of known failure keys (configurable, defaults to standard Authboss HTMLData errors).
- Fix a bug where content-types like 'application/json;charset=utf-8' would not trigger api responses in the default responder.
- Fix LoadCurrentUser error handling, it was swallowing errors when users were not logged in, changed to be consistent, now returns ErrUserNotFound just like CurrentUser.
- Fix a bug where EventAuth and EventAuthFailure were not being fired in the 2fa modules which would stop users from becoming locked on 2fa failures or logging in without being confirmed.
- Add sms2fa and totp2fa packages so users can use two factor authentication
- Add twofactor package to enable 2fa recovery codes for sms2fa and totp2fa
- Add OTP module so users can create one time passwords and use them to log in.
- Add more documentation about how RegisterPreserveFields works so people don't have to chase the godocs to figure out how to implement it.
- authboss.Middleware now has boolean flags to provide more control over how unathenticated users are dealt with. It can now redirect users to the login screen with a redirect to the page they were attempting to reach and it can also protect against half-authed users and users who have not authenticated with two factor auth.
- Ensure all uses of crypto/rand.Read are replaced by io.ReadFull(rand.Reader) to ensure that we never get a read that's full of zeroes. This was a bug present in a uuid library, we don't want to make the same mistake.
- LoadClientStateMiddleware no longer panics when LoadClientState fails. Instead it logs error messages and gives a 500 server error to users instead of returning no response from the server at all due to panic.
- Fix a bug where LoadClientState could return a nil request if the state returned nil instead of falling through.
- Fix Middlewares link in README
- Fix error message when forgetting authboss.LoadClientStateMiddleware to be a bit more indicative of what the problem might be.
- The upstream golang.org/x/oauth2 library has changed it's API, this fixes the breakage.
- RememberingServerStorer now has context on its methods
-
Recover and Confirm now use split tokens
The reason for this change is that there's a timing attack possible because of the use of memcmp() by databases to check if the token exists. By using a separate piece of the token as a selector, we use memcmp() in one place, but a crypto constant time compare in the other to check the other value, and this value cannot be leaked by timing, and since you need both to recover/confirm as the user, this attack should now be mitigated.
This requires users to implement additional fields on the user and rename the Storer methods.
Mostly rewrote Authboss by changing many of the core interfaces. This release is instrumental in providing better support for integrating with many web frameworks and setups.

v2 Upgrade guide (tov2.md)
-
API/JSON Support
Because of the new abstractions it's possible to implement body readers, responders, redirectors and renderers that all speak JSON (or anything else for that matter). There are a number of these that exist already in the defaults package.
-
The core functionality of authboss is now delivered over a set of interfaces
This change was fairly massive. We've abstracted the HTTP stack completely so that authboss isn't really doing things like issuing template renderings, it's just asking a small interface to do it instead. The reason for doing this was because the previous design was too inflexible and wouldn't integrate nicely with various frameworks etc. The defaults package helps fill in the gaps for typical use cases.
-
Storage is now done by many small interfaces
It became apparent than the old reflect-based mapping was a horrible solution to passing data back and forth between these structs. So instead we've created a much more verbose (but type safe) set of interfaces to govern which fields we need.
Now we can check that our structs have the correct methods using variable declarations and there's no more confusion about how various types map back and forth inside the mystical
BindandUnbindmethods.The downside to this of course is it's incredibly verbose to create a fully featured model, but I think that the benefits outweigh the downsides (see bugs in the past about different types being broken/not supported/not working correctly).
-
Support for context.Context is now much better
We had a few pull requests that kind of shoved context.Context support in the sides so that authboss would work in Google App Engine. With this release context is almost everywhere that an external system would be interacted with.
-
Client State management rewritten
The old method of client state management performed writes too frequently. By using a collection of state change events that are later applied in a single write operation at the end, we make it so we don't get duplicate cookies etc. The bad thing about this is that we have to wrap the ResponseWriter. But there's an UnderlyingResponseWriter interface to deal with this problem.
-
Validation has been broken into smaller and hopefully nicer interfaces
Validation needs to be handled by the BodyReader's set of returned structs. This punts validation outside of the realm of Authboss for the most part, but there's still helpful tools in the defaults package to help with validation if you're against writing rolling your own.
-
Logout has been broken out into it's own module to avoid duplication inside login/oauth2 since they perform the same function.
-
Config is now a nested struct, this helps organize the properties a little better (but I hope you never mouse over the type definition in a code editor).
- Notable removal of AllowInsecureLoginAfterConfirm
- Fix bug where e-mail with only a textbody would send blank e-mails
- Use of gopkg.in, it's no longer a supported method of consuming authboss. Use manual vendoring, dep or vgo.
This change is potentially breaking, it did break the sample since the supporting struct was wrong for the data we were using.
Lock: The documentation was updated to reflect that the struct value for AttemptNumber is indeed an int64. Unbind: Previously it would scrape the struct for the supported types (string, int, bool, time.Time, sql.Scanner/driver.Valuer) and make them into a map. Now the field list will contain all types found in the struct. Bind: Before this would only set the supported types (described above), now it attempts to set all values. It does check to ensure the type in the attribute map matches what's in the struct before assignment.
This breaking change allows multiple sites running off the same code base to each use different configurations of Authboss. To migrate your code simply use authboss.New() to get an instance of Authboss and all the old things that used to be in the authboss package are now there. See this commit to the sample to see precisely how to make these changes.
