Per-tenant limits, with the user choosing which device session to end.

Argon2id & breach screening

Passwords hashed with Argon2id and screened against known breaches with k-anonymity.

Multi-factor & passkeys

Passkeys, authenticator apps and email codes as second factors.

Behavioural security analytics

Sign-in patterns are analysed to flag unusual activity early.

Verified professional email

Verification, reset and one-time-code emails sent from a verified domain.

Multi-tenant platform & RBAC

Each organization is isolated, with role-based access control inside it.

Durable storage & signing keys

Signing keys live in a managed key service, with rotation and failover.
