Verified identity

For the Neuro sandbox, follow the account and identity quickstart, which uses public account enablement and automatic test-identity approval. The guide below covers the general provider-managed process. Create an account, a signing key, and an approved Legal Identity so your user can sign agreements and own assets.

Start from where you are

What you have now	What to do next
No Neuron host or provisioning method	Ask the operator for the host, onboarding method, required fields, review provider, and test-data policy.
Existing account credentials	Sign in with the existing account, then continue with key creation.
No account and a trusted backend	Follow User onboarding.
No account and an interactive browser flow	Follow Browser-based signup.
A current Legal Identity and signing key	Continue to Agreements or Digital signatures.

Current Legal Identity

An account answers who controls the session. A Legal Identity identifies the person or organization whose information has been reviewed. Logging in does not create or approve a Legal Identity.

Choose an onboarding method

Application	Method	Credential handling
Trusted backend	User onboarding	The backend protects the account-creation secret.
Browser	Browser-based signup	The browser uses the hosted flow; no API secret is exposed.
Existing Neuro user	Sign in with Neuro	Reuse the user’s existing account and identity.

Complete the identity stages

Create and verify an account.
Create a cryptographic key.
Apply for a Legal Identity.
Upload each required attachment.
Call ReadyForApproval to start review, unless the sandbox has already approved the identity.
Observe review and approval.

Identity review is asynchronous. Persist the application state and do not continue to a dependent workflow until the identity is approved.

Keep the resulting state

State	Why you need it
Account identifier	Associate the Neuro account with the correct application user.
Verified contact status	Resume any deployment-required contact verification.
`keyId`	Select the correct cryptographic key for later actions.
Identity application state	Resume and display pending review.
`legalId`	Identify the actor in signatures, contracts, and other trusted workflows.
Approval or rejection state	Decide whether the next dependent step is allowed.
