ZOREAL Identify

Alternatives to Supabase Auth

"Supabase Auth makes it easy to implement authentication and authorization in your app": it is the authentication component of the Supabase platform, verifying email and password, magic link, one-time code, social, custom OAuth2 or OIDC and SAML credentials and issuing JSON Web Tokens that the app and Postgres row-level security consume. ZOREAL Identify is a "Continue with ZOREAL" button on standard OpenID Connect, backed by the ZOREAL ID credential, that returns a pairwise pseudonymous identifier for a human verified against a government document chip, with the assurance of each login stated in the token. This page sets the two side by side: where each sits in the stack, what each token proves about the person, and what each costs.

Information last reviewed 10 September 2026. Compared: Supabase Auth with ZOREAL Identify. The Supabase database, storage and edge functions, and Supabase’s funding beyond the figures it publishes, are out of scope.

Where ZOREAL Identify and Supabase Auth differ

  • The guarantee

    ZOREAL guarantees that the person is real, is not an AI, exists, and is linked to a government-issued ID. One hundred percent, not ninety-nine point nine. ZOREAL is the only solution in the world today that can give that guarantee.

  • Database auth layer, or identity provider

    Supabase Auth verifies a credential and issues a JWT that the app and Postgres row-level security consume, with 19 social providers listed and any "OAuth2 or OIDC-compatible identity provider" for custom set-ups; what its token proves is the credential or the upstream provider’s result. ZOREAL is an upstream OpenID Connect provider; a Supabase project can consume it as a custom provider, and its third-party auth feature accepts external JWTs, while the app keeps Supabase tokens and row-level security.

  • What is known about the person

    Any identity proofing, document verification or liveness is not stated in the Supabase Auth materials we reviewed. ZOREAL builds the document chip read, the face match and the liveness capture into enrolment, and states per login in acr and amr whether a fresh capture, a registered hardware key or a remembered session authenticated this session.

  • Per user, or only when disclosing

    Supabase’s Free plan is "$0/month" with "50,000 monthly active users"; Pro is "from $25/month" with "100,000 monthly active users" then "$0.00325 per MAU", and SSO users "50 included, then $0.015 per MAU" (supabase.com/pricing, USD, September 2026). ZOREAL: Free to enrol, free Tier A logins; only Tier B logins charged; there is no per-MAU meter, and current prices are on the ZOREAL price list at zoreal.com/pricing.

Comparison of ZOREAL Identify and Supabase Auth, based on public materials reviewed on 10 September 2026.

AttributeZOREAL IdentifySupabase Auth
Role in the stackAn upstream OpenID Connect identity provider at id.zoreal.com; the relying party redirects, the holder approves on their phone, and a stock OIDC library validates the ID token against ZOREAL’s JWKS. ZOREAL is not an authentication layer or user store for the relying party’s own users.The authentication component of the Supabase platform, using "JSON Web Tokens (JWTs) for authentication", with the JWT consumed by the app and by Postgres row-level security (Supabase Auth guide).
How the identity is boundEnrolment, in the ZOREAL ID app: the document is photographed, its machine-readable zone read and its chip read over NFC. The server re-runs Passive Authentication against its own trust store built from the ICAO Public Key Directory, so the issuing country’s signature over the data is checked on ZOREAL’s side, and the chip proves possession of its private key. A liveness capture with presentation-attack detection is face-matched 1:1 against the chip portrait. The device key is generated in the phone’s hardware, its attestation is verified at registration, and every evidence call carries an app-integrity assertion. Each verified document yields two holder certificates over that key under ZOREAL’s two roots (ECDSA P-384 and ML-DSA-87), one pseudonymous and one carrying the legal name, valid until the document expires. Login: ZOREAL is the OpenID Provider. The holder approves on their phone, a stock OIDC library validates the ID token against ZOREAL’s JWKS, the relying party sets the assurance per request with acr_values, max_age and prompt, and a request that cannot meet its floor is denied, never downgraded. The subject is pairwise per sector, so one ZOREAL ID is reused at every service without being linkable across them; consent is remembered per sector and re-prompted on any new scope.Supabase Auth verifies a credential (email and password, magic link, one-time code, social OAuth from Apple, Azure, Bitbucket, Discord, Facebook, Figma, GitHub, GitLab, Google, Kakao, Keycloak, LinkedIn, Notion, Slack, Spotify, Twitter, Twitch, WorkOS and Zoom, a custom OAuth2 or OIDC provider, or SAML SSO on paid plans) and issues a JWT (Supabase Auth guide; pricing). A document check or liveness is not stated in the public materials we reviewed.
What the token provesTwo halves. Proof that a real human is there: the ID token asserts this is one human (not one account, not one device), with the strength of that claim in a uniqueness field; that a government document chip was read and its authenticity verified, at the month given; and how this session was authenticated, in acr and amr, whether a live human was captured for this login, a registered device key was used, or a session was reused. And, when the relying party requests it and the person consents on the phone, the verified identity: name, birthdate and document details read from the chip, served from userinfo to a confidential client with a verified domain. The person sees every requested claim before approving, and the relying party receives only the scopes it was granted. It is not KYC, not a legal signature, not proof that the person consented freely, and not proof that the person is the one operating the browser.The credential or the upstream provider’s result, carried in a JWT (Supabase Auth guide).
GuaranteeZOREAL guarantees that the person is real, is not an AI, exists, and is linked to a government-issued ID. One hundred percent, not ninety-nine point nine.Not stated in the public materials we reviewed (Supabase Auth guide, pricing, Series F release, terms).
Who issues the credentialZOREAL is the issuer of the ID card: a reusable identity credential that logs in to other websites, with the person controlling the scopes each login discloses.Supabase Auth issues the JWT for the project after verifying a credential or an upstream provider; each project holds its own users (Supabase Auth guide).
Identity proofingBuilt into enrolment (document photographed, machine-readable zone read, chip read over NFC and verified server-side, flash-plus-zoom liveness capture face-matched 1:1 to the chip portrait) and, on request through acr_values, into a login: a live floor requires a presence attestation minted after scoring a fresh capture, and a pairing that cannot meet its floor is denied, never downgraded.Not stated in the public materials we reviewed (Supabase Auth guide, pricing).
Cost to enrolEnrolment in the ZOREAL ID app is always free for the person holding the identity: document scan, chip read and liveness enrollment, re-enrollment, recovery and revocation. Every Tier A login is free without limit on every plan: the pairwise identifier, the assurance block, age-threshold answers and nationality, with 1 client configuration on Free. Answering an identity request is always free for the person.The project’s users are created in Supabase or arrive through a provider; the Free plan is "$0/month" with "50,000 monthly active users" and third-party MAU "50,000 included", SSO not included, and "Free projects are paused after 1 week of inactivity" (supabase.com/pricing, USD, September 2026).
Cost per sign-inEnrolment is free: "The ZOREAL ID app is always free for the person holding the identity, from enrollment to recovery", and "Document scan, chip read and liveness enrollment" is "Always free" on Free and Premium. Every Tier A login is free, without limit, on every plan: the pairwise identifier, the assurance block, age-threshold answers and nationality (openid, zoreal.age and zoreal.nationality, available to every registered client). Tier A logins are never charged. A charge applies only to a qualified Tier B login, where the relying party requests identity disclosure (the profile scopes, name, birthdate and document details, and email, which require a verified domain, a confidential client and client authentication), on Premium: "Identify · Identity disclosure", "Name, birth date and document details", "One charge for name, birth date or document details, even when several are returned"; "Identify · Fresh-liveness login", "Coming soon"; "Content and contract signing authorization", "Coming soon". Client configurations per website or app: 1 on Free, 10 on Premium; private-key JWT and mTLS client authentication on Premium. Premium is priced per user, monthly or yearly, with two months free on yearly billing; every organization member is a paid Premium seat; metered usage is charged separately. Enterprise: contact us. Answering an identity request is always free for the person. Current prices are on the ZOREAL price list at zoreal.com/pricing. ZOREAL Identify is the cheapest way to do KYC in the market: free to enrol, free to check, paid only for the higher disclosure tiers.Priced per monthly active user, not per sign-in. Pro: "from $25/month", "100,000 monthly active users" then "$0.00325 per MAU", SSO "50 included, then $0.015 per MAU", spend caps on by default; Team: "from $599/month" with the same MAU and SSO rates; Enterprise: "custom pricing" (supabase.com/pricing, USD, September 2026).

Where ZOREAL Identify and Supabase Auth agree

Supabase Auth gives an app a convenient sign-in for its users at no cost up to 50,000 monthly active users, with the identities of Google, Apple, GitHub and sixteen other providers reused and a JWT handed to the app and the database. ZOREAL Identify is also free for the person from enrolment onward and free for basic sign-ins on every plan. Both are OpenID Connect and JWT based, and both hand the app a signed token to validate.

The two occupy different layers. Supabase Auth is the app’s authentication layer, tied to Postgres row-level security; ZOREAL is an upstream identity provider that Supabase can consume as an OIDC-compatible custom provider, or whose token the third-party auth feature can accept. A relying party on Supabase keeps its Supabase JWTs and row-level security and adds ZOREAL’s claims. Neither asserts a legal signature, and neither is KYC.

What differs is the assurance behind the identifier. Supabase’s token proves the credential or the upstream provider’s result, with no document check or liveness stated; ZOREAL’s token states that a human was verified against a government document chip and how this particular login was authenticated.

ZOREAL Identify may fit you if

  • You need to know that a real human verified against a government document chip is behind the account, with the strength of each login stated in acr and amr
  • You want a pairwise identifier per sector and no personal data in the ID token
  • You want age thresholds and nationality as yes-or-no answers without a birthdate, on the free tier
  • You want Tier A logins free without limit and a charge only on a Tier B login where identity is disclosed, rather than a per-MAU meter

Supabase Auth may fit you if

  • Your app already runs on Supabase Postgres and you want authentication tied to row-level security
  • You want 50,000 monthly active users free, then $0.00325 per MAU above 100,000 on Pro
  • You need many social providers out of the box: 19 are listed, plus custom OAuth2 or OIDC and SAML SSO on paid plans
  • You do not need assurance about the person from the authentication layer itself
