How to configure PhenixID Authentication Services for public clients (SPAs, embedded browsers)
For applications without it's own backend, such as SPA applications and embedded browsers, there's no storage for secrets (such as client_secret).
PhenixID recommends such public clients (ie clients without a secret) to use the authorization code flow with the PKCE extension.
Configure PhenixID Authentication Services
- Create a relying party with a client_id, client_secret (set to anything as this won't be used) and allowed redirect URIs.
- Setup PhenixID Authentication Services by following this guide.
