17 projects are authentication, listed alphabetically. Written in 5 languages, most of them open source.

Authentication software manages users and sign-in: passwords, single sign-on over protocols such as OpenID Connect or SAML, multi-factor login and permissions. Applications hand login over to it instead of building their own. A record carries this category when identity and access are a main function, as for a standalone identity provider or a [backend platform](/categories/backend/) with built-in auth. Keycloak and authentik are examples.

## Questions

### What is the best authentication?

We can't tell from here. What suits an editor-heavy marketing site can be wrong for a static documentation site. The list is alphabetical and nobody paid for a place on it.
