What do these mean?
- Social login
- Let people sign in with an account they already have, such as Google or GitHub.
- Passwordless sign-in
- Sign in with a link or a one-time code sent by email, with no password to remember.
- Multi-factor authentication
- A second step at sign-in, such as a code from an authenticator app, so a stolen password is not enough.
- Custom domain
- The sign-in pages and emails live on your own address, like login.yourapp.com, not the vendor's.
- Passkeys
- Sign in with a fingerprint, face or device PIN instead of a password. Harder to phish.
- Remove vendor branding
- Hide the "secured by" badge on the prebuilt sign-in screens.
- User data export
- Download all your users' records so you can move to another provider.
- Organizations (teams)
- Group users into companies or teams, each with its own members and settings. Needed for B2B apps.
- Roles and permissions
- Decide what each user may do, for example admin versus member.
- Enterprise single sign-on (SAML)
- Let a customer's staff sign in with their company login (Okta, Microsoft Entra and similar). Big customers often require this.
- Automatic user provisioning (SCIM)
- A customer's IT team adds and removes your app's users from their own directory.
- Audit logs
- A record of who signed in and what changed, for security reviews and compliance.
- Machine-to-machine tokens
- Credentials for one backend service to call another, with no human signing in.
- Uptime guarantee (SLA)
- A written promise of availability, such as 99.99%, usually with credits if it is missed.
5 of 6 alternatives cover what you need. The cheapest of those saves $2,100 (100%) a month.
Visitors who say they use Auth0: none yet. Self-reported and never used for order.
Cover everything you need
Cheaper, but missing things you need
Every user who signs in during the month counts once. Monthly billing, list prices, the cheapest plan that covers the size and everything you need. Clerk counts "retained" users (people who return a day or more after signing up), which is fewer than active users, so its bill can be lower than the same number of active users would suggest. Enterprise-connection, SMS and other metered extras are not included. A blank price means the vendor publishes no price at that size. Auth0's Free plan costs $0 at 1,000 monthly users but lacks: multi-factor authentication.

Switches are reported by visitors, shown as raw counts, and never affect the order. "None yet" means nobody has reported that switch yet.
"Not stated" means we found no statement either way on the vendor's own pages, not that the feature is missing. Cost is the cheapest plan that covers the size and everything you need. Each tool page lists its sources and the date each price was checked.
