feat: login & registration via code #3378

Benehiko · 2023-07-12T15:57:09Z

Implements Login and Registration via the code strategy.

Related issue(s)

This feature adds passwordless email code login. When a user signs up, or signs in, a code is sent to their email address which they can use to complete the authentication process.

This feature is currently only working for browser facing APIs.

Closes #2029
Closes https://github.com/ory-corp/cloud/issues/3573

Very nice! I still need to review the login tests, the registration code, and the registration tests, as well as e2e and trying out the flow myself. In summary, this looks great! There are a few things we need to address:

Should we enable / disable login / regstration for the code method? If yes, then why not also for verification / recovery?
The introduced state parameters are not "backwards" looking - they only apply to the new flows which I find a bit strange?
The SQL migrations should be kept in as few files as possible and avoid DEFAULTs on existing large tables
The state machine we use in login/registration sets values in the callbacks of outer functions. If a callback is not called, these values might be nil, leading to panics

I'm wondering if we should use a different credential name here. oob_otp (out of band one time password) is probably the "correct" terminology, but noone understands what this means.

What are your thoughts?

otp?. code is also okay since the method you need to enable is code.

Take a look at the password tests - we are testing various flows there (browser html, browser ajax, native api) and I think we need to do this here and in registration too. There are also some testhelpers you can use to easily submit these flows!

Are you sure these are all strings allways?

I actually don't know tbh. I also don't know what the best way would be to check if the traits are the same between the submitted UI nodes and the DB UI nodes :/

Maybe @zepatrik knows more about UI node checking ;)

Some things to consider before merging:

The SPA experience isn't that great with this PR since the SDK for one returns the successfulNativeLogin object on login submit.
https://github.com/ory/kratos/blob/master/selfservice/flow/login/handler.go#L687

See this example:
https://github.com/ory/kratos-selfservice-ui-react-nextjs/pull/59/files#diff-efe206089575e5aa92a4bacded0c0c25b4ef6b11199e0d8620eecd1d65b66f50R79-R81

One alternative would be to return the continue_with property like we do in the registration flow when a verification flow is needed.

if (data.continue_with) {
...
}

The naming and configuration. Right now all of the UI nodes are under the code group which I think is fine since this is the same group we use in Recovery and Verification when they use the code method.
The configuration keys need a bit of adjustment. As mentioned by @aeneasr we could use something like this:

code:
  enabled: true # enables verification, recovery
  passwordless_enabled: true # additionally enables passwordless flows
  # aal2_enabled: true

Which I'm in favor of.

A lot of the scaffolding for the settings flow is already in this PR and can be done in a follow-up PR. This reduces the size of the PR and makes it easier to review.
We need to merge feat: registration & login with code elements#117 and feat: login and registration via code kratos-selfservice-ui-react-nextjs#59
To get the tests passing on kratos-selfserivce-ui-react-nextjs and kratos-selfservice-ui-node we would need to do an SDK pre-release off of this branch.

jonas-jonas · 2023-08-23T11:26:51Z

Where do you need to "redirect"/continue to?
That sounds good to me. In recovery/verification we have the use key that indicates whether to use link/code, maybe something like that is an option here, too?
SGTM

To get the tests passing on kratos-selfserivce-ui-react-nextjs and kratos-selfservice-ui-node we would need to do an SDK pre-release off of this branch.

Make sure to actually do a pre-release, if you just use a random id it is uploaded as the latest package. (I had that happen a while back.)

This looks very good! I just had some minor questions and one security concern regarding the code that checks the code.

This for loop looks a bit concerning. If an attacker can create multiple login codes in quick succession, the probability that one of the codes matches a random guess rises.

From a security perspective we should only ever check against one login code, IMHO the latest.

hmm, i added this since you could have multiple identifiers listed under the code credentials type.

The user submits one of those identifiers, an email is sent out to all of their identifiers linked to the code credential. Each email contains a unique code. The second submit the user can submit any of the codes sent out.

See this identity schema https://github.com/ory/kratos/blob/f1a0fae19e32014a9151f320ed2ad6a903f129ea/test/e2e/profiles/code/identity.complex.traits.schema.json

I think you're both right. In the default case, where an identity has only one or two "login emails", I think that Alano is correct. As far as I can tell, multiple codes (related to one flow id) would only ever be sent out if the identity schema has more than one code credentials identifier.

However, if an identity schema allows an array of identifiers (so 1..n emails used for login), this could theoretically be abused.

I guess this can be fixed by sending EVERY address the same code. At the moment we send every address a different code, which makes brute forcing more likely because we reduce the search space.

Does that make sense?

hmm true, i didn't think of that 🤔

Yeah i agree, sending each the same code will prevent this.

I had to revert this logic, every address needs a unique code, otherwise we don't know which address got the code - and thus can't verify the correct email.

This function is very similar to UseLoginCode. Can we extract this out into a generic function?
