Daegun ID
id.daegun.dev
Daegun ID is a personal identity service: one Google sign-in for the small set of applications that run on daegun.dev domains. Instead of each application handling sign-in separately, you sign in here once with your Google account and each application you use recognizes you. It is not a commercial service and is not open to the public — accounts are limited to people the operator invites.
What it does
Signing in uses Google for your name, email address, and profile picture — nothing more. No passwords exist here. When a daegun.dev application asks you to sign in, you are shown which application is asking and approve it once; you can see and revoke those approvals from your profile. Each application decides for itself what you can do in it.
Google Calendar
Some daegun.dev applications offer features that work with your Google Calendar — for example showing your schedule or adding an event you asked for. That access is never part of signing in: an application that needs it asks you separately, requests only the narrowest calendar permission its feature needs, and uses your calendar data only to provide that feature. Details are in the privacy policy.
