# Security and identity

- Canonical: https://siax.io/en/use-cases/secure-identity
- Language: en
- Publisher: SIAX Technology AB, siax.io

Sign-in and SSO, password management and secrets for your apps and teams.

## Problems it solves

- People have a separate login for every system, and leavers keep access too long.
- Passwords and API keys end up in configuration files, chat and spreadsheets.
- Identity and sign-in costs grow with every user and every application you connect.

## Open source projects

- [ZITADEL](https://siax.io/en/projects/zitadel): AGPL-3.0-only (verified)
- [Infisical](https://siax.io/en/projects/infisical): MIT (verified)

## Services it can replace

- [Auth0](https://siax.io/en/alternatives/auth0): ZITADEL: Direct alternative, Verified (<https://zitadel.com/blog/zitadel-vs-auth0>)

## Components to combine

- Open in the stack builder: https://siax.io/en/stack-builder?v=1&saas=auth0/auth0

## Limitations

- Zitadel is licensed AGPL-3.0, a network copyleft licence: modified versions offered over a network must be shared with their users. (From the project's record: <https://raw.githubusercontent.com/zitadel/zitadel/ac241d217794f1a8dc0e0ce0a328495e1e54de19/LICENSE>)
- Infisical is recorded as open core: some features are outside the part released under the MIT licence. (From the project's record: <https://raw.githubusercontent.com/Infisical/infisical/5a4984842ad8546dd77b9fd8749e787299d9add5/LICENSE>)
- Sign-in sits in front of every other system. Plan for availability and tested backups before you move users. (SIAX assessment)

## Running cost

Self-hosting is not free: servers, backups and your own time cost money. These figures are estimates; minimum resources come only from the project's own documentation.

- ZITADEL: minimum resources not yet assessed.
- Infisical: minimum resources not yet assessed.
