The difference
Provara does not answer the identity question, but the authorisation question — verifiable, time-limited and revocable at any time.
Not the question
“Is Stefan really Stefan?”
But rather
“May Stefan sign a contract of up to CHF 50’000 on behalf of b-nova?”
A controlled lifecycle
From issuance through verification to instant revocation — every authorisation stays under your control.
Issue
Choose the credential type, capture the details, set the validity. Provara generates a cryptographically signed credential (SD-JWT VC), a QR code and a public verification link.
Present
The authorised person presents the credential as a card, QR code or link — data-minimised and limited to the details required.
Verify and revoke
Any party verifies in seconds, without an account. You retain control and revoke at any time — verification detects the revocation immediately.
Authorisations that matter in your business
Five ready-to-use credential types — or model your own.
Signing authority
Who may sign legally binding commitments for the organisation, and up to what amount?
Power of attorney
Trustee and representation mandates — granted, time-limited and revocable at any time.
Construction site access
Access and safety credentials for people on the construction site, including short-lived ones.
Supplier approval
Verifiable compliance status of suppliers — delivered straight into your ERP via webhook.
Project role
Temporary roles and signing rights that automatically expire with the project.
Custom credential types
Model your own authorisation — fields, public visibility and validity.
On the Swiss trust infrastructure
Trust you can prove technically.
No photocopy, no PDF — cryptographically signed credentials based on open standards that every party can verify independently.
Verifiable credentials
SD-JWT VC (ES256) on the swiyu infrastructure — verifiable in the government wallet, not merely as a document.
Instant revocation
IETF Token Status List: verification always checks both signature and status. A revocation takes effect immediately.
Data-minimised by design
Only what is necessary appears publicly — no internal identifiers, no full claims, IP addresses hashed exclusively.
API and Webhooks
Machine-to-machine issuance via API key; signed Webhooks with a transactional Outbox for your systems.
SwissID and e-ID sign-in
Sign in with SwissID or the government e-ID, with multi-factor authentication and step-up re-authentication.
Audit-proof audit log
Hash-chained and append-only — every issuance, verification and revocation documented tamper-proof.
