Before you choose
Start with the plan model
Several entries, such as Amazon Cognito, Apereo CAS, Authelia, authentik, Cisco Duo Passwordless, Clerk, Descope and Frontegg, include a free plan. Check what the free tier covers before moving to paid use.
For example, Amazon Cognito starts at $0.01 per user per month, authentik costs $5 per user per month with annual billing, and Clerk starts at $20 per month with annual billing.
Check trial access
A free trial can help you review a paid service before committing. Authsignal lists a 30-day trial, and Cisco Duo Passwordless lists a 30-day trial alongside its free plan.
Match the platforms
Tools in this list run on combinations of web, Android, iOS, API, Windows and macOS environments. Match the platform support to the systems where sign-in needs to work.
Compare sign-in methods
Compare a product's sign-in handling through the authentication-protocol and MFA-method fields. Because passkey sign-in has its own field, check it when passwordless access matters.
Review connections and scale
Existing-system identity connections may depend on directory sync. Check deployment to understand how a product can enter service, and view monthly active users as a published usage figure alongside the plan.
