Device Authorization (IDE Sign-in)

CodePus IDE uses OAuth 2.0 Device Authorization Grant (RFC 8628). No password is ever entered into the IDE.

Flow

IDE → top-right “Sign in”

IDE shows user_code (e.g. ABCD-1234)

Browser opens https://codepus.ai/device, enter code

Approve in browser → IDE auto-signs in

access_token: 1 hour, auto-rotated

refresh_token: 60 days

Re-authentication required after expiration

Dashboard → Security → Devices. Revoke any session immediately.
