Shield is the most feature complete authentication framework based the standard Go HTTP and Postgres.
It is built on top of sqlc, pgx and supporting SSO, password-based authentication, MFA, SAML, sessions out of the box.
Will shield support other databases (mysql, sqlite, database/sql, etc.)?
No, not at the moment. There is no intention to adapt this framework for other stacks in the near future. As focusing on a specific technology stack it helps to iterate faster and delivery more stable features.
Later, however, support for additional stacks can be added.
