How Much Are Free Authentication Credits Worth?
Authentication credits run from a few hundred dollars to about $10,000 at the top end. That looks small next to a cloud grant, and it is sized almost exactly right for what auth costs before you have revenue.
An auth credit is not runway. It covers a fixed monthly line item through the stretch where that line item is pure cost. Nobody argues about a compute bill that usage is driving. Teams argue constantly about a subscription for a login box.
AI Perks tracks authentication programs inside the Security category alongside $7.7M in credits across 194 companies. Eligibility depends on stage and funding, and the live terms for each program are listed there.

What an Authentication Provider Is Actually For
You are not buying a sign-in form. You are buying session handling, token rotation, credential storage, multi-factor enrollment, social and enterprise single sign-on, and an audit trail you can hand to a security reviewer.
The login screen takes an afternoon. The rest takes a year and generates incidents when it is wrong: refresh token rotation and reuse detection, session revocation, password resets that cannot be used to enumerate accounts, rate limiting against credential stuffing, and safe handling of an email change.
Three distinct product classes sit here, and confusing them is the most expensive early mistake:
- Consumer identity (B2C) - individual accounts, social login, passwordless and passkeys. Priced per monthly active user. The user is the unit.
- Business identity (B2B) - organizations, roles, invitations, SAML and OIDC single sign-on, SCIM provisioning. The company is the unit, and the data model is genuinely different.
- Workforce identity - your own employees signing in to your SaaS stack. This is Okta territory, and it solves an internal problem rather than a product one.
A B2C schema that later becomes a B2B schema is one of the harder migrations a young product goes through, since it touches every authorization check you wrote.
How Authentication Cost Behaves at Scale
Auth is not a smooth volume bill. It is a step function: a monthly active user allowance you eventually cross, then a single large jump the first time you have to sell to an enterprise.
Approximate bands, which move often and should be checked against the vendor:
| Stage | Typical monthly auth bill | What triggers the next step |
|---|---|---|
| Pre-launch and early users | $0 on a free tier | Crossing the included MAU allowance |
| Tens of thousands of MAU | Low hundreds | Per-user charges above the included tier |
| First enterprise customer | Hundreds to low thousands | SAML, SCIM and audit logs sit on a higher plan |
| Regulated or high volume | Low thousands and up | MFA message costs, custom domains, support terms |
Four things generate the invoices founders did not expect.
The SSO tier. Enterprise single sign-on is the classic upsell gate in this category. One customer asking for SAML moves you up a plan and multiplies the bill, and that customer will not accept a delay.
SMS as a second factor. Text-message MFA is billed per message on top of the subscription, and SMS pumping fraud, where attackers farm traffic to premium numbers through your signup form, can turn that into a real loss in a weekend. Authenticator apps and passkeys cost nothing per use.
Machine-to-machine tokens. Service-to-service authentication is often metered separately from human users, so a chatty microservice architecture can outspend your actual customers.
MAU definitions. Every vendor counts a monthly active user differently, and a background job refreshing a token can mark a dormant account active. Read the definition before forecasting, and compare vendors in the Security category on AI Perks.

Authentication Credit Programs Compared
Auth0 offers the largest published amount at up to $10,000, Okta $8,000 for workforce identity and Clerk $500, while Supabase folds auth into a $300 platform credit. Several developer-first vendors run partner tracks with no published number.
| Provider | Strongest at | Pricing shape | Credit scale |
|---|---|---|---|
| Auth0 | Consumer and enterprise identity in one mature vendor | Per MAU, enterprise features on higher tiers | Up to $10,000, largest published in the category |
| Okta | Workforce identity, employee SSO, provisioning | Per employee, per product | Up to $8,000 |
| Clerk | React and Next.js drop-in, fastest to ship | Small monthly base plus per MAU | $500 |
| Supabase | Auth bundled with Postgres and storage | Included in the platform plan, MAU-based above free | $300 platform credit covering auth plus database |
| WorkOS | Adding enterprise SSO and SCIM to auth you already have | Typically per enterprise connection, not per user | Partner tracks, amounts not consistently published |
| Stytch | Passwordless, passkeys, device and fraud signals | Per MAU with a free tier | Startup and partner tracks, modest |
| Firebase and Google Identity Platform | Mobile-first consumer apps | Free for core auth, paid above a tier | Covered indirectly by general cloud credits |
| Self-hosted (Keycloak, Ory, FusionAuth) | Full control, data residency | No license cost, you pay in engineering time | Not applicable, offset with cloud credits |
Where a number is missing, the program is negotiated per applicant or not published, and an invented figure is stale the week it appears. Current values, eligibility and terms sit on AI Perks.
How to Choose and in What Order to Apply
Pick the provider on whether you sell to people or to companies, then apply largest first: the broad cloud program, then the identity vendor, then any enterprise SSO layer.
Settle B2C versus B2B before you write a line of auth code. If organizations, seats and invites are in your product's future, pick a provider whose data model already has them. Retrofitting multi-tenancy costs a quarter you did not budget.
Cloud program first. It is the largest single amount available, approval odds fall as your company gets older, and it covers hosting, storage and Google's own identity products in one grant. Filter to the cloud and infrastructure categories on getaiperks.com.
Identity vendor second. Apply once you know your user shape. A credit granted before you have signups burns down against an empty product, and most balances run on a clock.
Enterprise SSO layer third. Only once a deal demands SAML or SCIM. Paying for that tier speculatively is the most common way teams waste an auth budget.
Never let a credit choose your provider. Password hashes are usually exportable, but MFA enrollments, sessions, social account links and custom role models generally are not, and every user who has to re-enroll becomes a support ticket. Put a thin internal interface between your application and your auth vendor on day one. It costs a day and is the difference between a migration and a rewrite.

What Founders Get Wrong About Auth Credits
The expensive mistakes are assuming a cloud grant covers the auth bill, and treating authentication as a checkbox rather than the layer every security review starts at.
- Assuming cloud credits absorb it. An identity vendor is a separate SaaS invoice, and AWS, Google Cloud and Azure credits do not touch it. That is what makes an auth credit additive: cloud credits cover where the code runs, model credits cover what it calls, auth credits cover who is allowed in.
- Rolling your own to save a small subscription. Building it takes a week. Maintaining rotation, revocation, abuse handling and the audit evidence a security questionnaire demands is permanent, paid in engineering time at full price.
- Shipping B2C auth into a B2B market. The first enterprise deal asks for organizations, SAML, SCIM and audit logs, none of which bolt cleanly onto a single-user account model.
- Conflating authentication with authorization. Who you are and what you may do are different problems, and encoding permissions in your identity provider breaks the moment they need to change faster than tokens expire.
- Ignoring the SMS line. Phone-based MFA is metered per message and is an active fraud target. Default to authenticator apps or passkeys, with SMS as a fallback.
- Letting the balance expire. An unused auth credit is worth exactly zero. AI Perks tracks terms so you can sequence approvals around real usage instead of claiming everything at once.
Frequently Asked Questions
Which authentication provider has the best free tier?
Supabase and Firebase are the most generous, because auth is bundled with a broader platform rather than sold alone. Most dedicated vendors include a monthly active user allowance that covers a prototype comfortably. Free tiers rarely include enterprise SSO or audit logs, which is where the real pricing lives. Terms are listed at getaiperks.com.
Do authentication startup credits actually exist?
Yes. Auth0 runs up to $10,000, Okta up to $8,000 for workforce identity, Clerk $500, and Supabase includes auth in a $300 platform credit. Several developer-first vendors run partner or accelerator tracks without published amounts. Eligibility depends on stage and funding, and the current programs are tracked at getaiperks.com.
Should I just build authentication myself?
Only if identity is your product. The sign-in flow is trivial; token rotation, session revocation, credential stuffing defence, MFA enrollment recovery and the audit trail a customer's security review demands are not. A vendor subscription that a credit can absorb is cheaper than the engineering weeks, and far cheaper than one breach.
Can I stack auth credits with cloud and AI credits?
Yes, and they cover genuinely separate bills. Cloud credits pay for where your code runs, model credits pay for inference, observability credits pay for knowing whether it works, and auth credits pay for who is allowed in. Holding several at once is how teams cover the whole early stack rather than a single layer of it.
How hard is it to migrate between auth providers?
Harder than vendors imply. Password hashes are usually portable, but MFA enrollments, live sessions, social account links, organization models and custom roles often are not, so some users must re-enroll. Budget weeks, run both providers in parallel during cutover, and keep an internal abstraction layer so the change is contained.
Do I need enterprise SSO before my first enterprise customer?
No, and paying for that tier speculatively is a common waste. Choose a provider that offers SAML and SCIM on an upgrade path, so the answer to a procurement questionnaire is a plan change rather than a migration. Buy the tier when a signed deal actually requires it.
Pick the auth provider you would still choose at list price, then let someone else cover the bill.
