On Ory Cloud, the current limitation is that only

"email"

is accepted as a valid value for the

recovery.via

field in the identity schema. This is confirmed by the error message you are seeing:

Value is not accepted. Valid values: "email".(1)

. While the Ory open-source documentation and schema examples show that

"sms"

is a valid option for self-hosted Ory Kratos, the knowledge sources do not indicate that SMS-based account recovery is currently supported on Ory Cloud. Only email-based recovery is available at this time. If you require SMS-based recovery, you may need to wait for future support in Ory Cloud or consider a self-hosted Ory Kratos deployment, where this feature can be configured as shown in the documentation for custom identity schemas and recovery addresses. However, for Ory Cloud, only

"email"

is accepted for the

recovery.via

field at this time [Customize identity schemas – Recovery address](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema#recovery-address) [Account recovery and password reset – Account recovery address](https://www.ory.sh/docs/kratos/self-service/flows/account-recovery-password-reset#account-recovery-address). I'm sorry, but there's no information in the knowledge sources indicating that SMS-based recovery is currently supported on Ory Cloud.
