Store non-sensitive information:
- Usernames
- Account numbers
- Email addresses
- User IDs
- Reference numbers
{
"type": "PLAIN_TEXT",
"label": "Username",
"value": "john.doe@acme.com"
}
Secure string blocks
Store sensitive information (encrypted at rest):
- Passwords
- PINs
- Access tokens
- API keys
- Security answers
{
"type": "SECURE_STRING",
"label": "Password",
"value": "MySecurePassword123!"
}
Custom blocks
Add jurisdiction-specific fields as needed. The block structure is flexible to accommodate any credential format.
Linking credentials
Link to business entity
Associate a credential with a business entity:
POST /business-entity/:businessEntityId/credentials/:credentialId
This makes the credential accessible when viewing the business entity.
Link to registration
Associate a credential with a specific registration:
POST /business-entity/:businessEntityId/registrations/:registrationId/credential/:credentialId
This links the credential to a specific government registration, enabling automated filing workflows.
Security
- Encryption: Secure string blocks are encrypted at rest using industry-standard encryption
- Access control: Credentials are only accessible to authorized users
- Audit logging: All credential access and modifications are logged
- Sharing: Credentials can be shared with accountants and service providers
Sharing with accountants
Credentials can be shared with external accountants and service providers who need portal access for filing and compliance work. The sharing mechanism ensures proper authorization and audit trails.
