Describe the bug

I'm trying to setup a passwordless phone registration flow. I've followed the docs and no matter what I do I get this error: credentials.code.via has unknown value "sms" when trying to send a SMS code. This is my identity schema:

{
  "title": "Person",
  "type": "object",
  "properties": {
    "traits": {
      "type": "object",
      "properties": {
        "phone": {
          "type": "string",
          "format": "tel",
          "title": "Phone number",
          "minLength": 3,
          "ory.sh/kratos": {
            "credentials": {
              "code": {
                "identifier": true,
                "via": "sms"
              }
            },
            "verification": {
              "via": "sms"
            }
          }
        }
      },
      "required": [
        "phone"
      ],
      "additionalProperties": false
    }
  }
}

I've tried all sorts of combinations, but nothing works. Here's my identity config:

Up for that, had the same issue with cloud Ory.

Which docs are you referring to?

Plain registration and login doesn't work yet, you'll still need an email address. You can, however, verify the phone number and use it for MFA.

I find it very confusing that you can enable passwordless login, but you cannot login with a SMS code.

I've spent countless hours trying to setup Kratos, so if the problem is that it's not supported, then I'll unfortunately have to use another IAM instead, unless you can give me an ETA for when it'll be supported.

According to the identity schema editor this is valid (and it's also not stated anywhere in the docs that it's not supported):

"code": {
  "identifier": true,
  "via": "sms"
}

Hi @jonas-jonas , is there a way to do Auth without Email? Only phone number? Because on UI schema allow to set code:via = sms but when we are doing Sign Up - we got this strange error that value is not supported 'credentials.code.via has unknown value "sms"'

Feb 26 '24 12:02 OlegOLK

@jonas-jonas sorry for spamming you, but I'm blocked until I know if it's something you're gonna support in the near future.

Feb 28 '24 14:02 marcus-sa

We're looking into it at the moment, but don't have a concrete timeline yet.

Mar 01 '24 08:03 jonas-jonas

Hey, sorry to hear that you're blocked. I think Jonas was pretty clear when he said that that OTP login with SMS is not (yet) supported. We don't have a timeline for this feature at the moment as we don't have enough commercial demand for it.

@aeneasr

AFAIK, SMS is not supported for "code" strategy, but it's already implemented for "password" strategy, is it correct? It means that, we can use Ory Kratos for a scenario to allow user to use phone number as a identifier, and use SMS to verify, then allow user to set password?
