Authentication

Halo signs in with your Memcode account. You do not need the Memcode CLI installed.

halo login

opens your browser at memcode.ai. After you sign in, the key is saved where the Memcode CLI keeps it, ~/.config/memcode/.env (readable only by you). That means:

• if you already use the Memcode CLI, Halo is signed in already;
• halo login signs the Memcode CLI in too, and halo logout signs both out.

Halo never reads a .env file in the folder you are working in, so a project cannot sign Halo into another account.

What the key is used for

Halo presents the key once when it connects, and the service exchanges it for a short-lived session. The key identifies your account to the Halo service. It is not permission to do anything on your computer: that is always decided on your machine.

CI and scripts

Set MEMCODE_API_TOKEN in the environment to use a key without signing in.
