The ChatGPT and ReminderIt login, explained

No password sharing, no key to copy. Here is what the OAuth consent screen does when you connect ChatGPT to ReminderIt, and how to revoke access later.

When you connect ChatGPT to ReminderIt, you sign in once on a consent screen and never touch an API key. That is OAuth doing its job. It is worth understanding what actually happens in that moment, because it explains why the connection is secure, what access you are granting, and how you take it back whenever you want.

Why there is no key to copy

The hosted connector uses OAuth precisely so you never paste a secret into ChatGPT. Instead of handing over a key, you prove who you are by logging in to ReminderIt directly, and ReminderIt hands ChatGPT its own limited access. Your password is never shared with ChatGPT.

This is the same pattern behind signing in to a new app with an existing account. You authorise, you do not hand over credentials.

What the consent screen asks

After you add the connector URL, ChatGPT sends you to ReminderIt's consent screen. You log in to your ReminderIt account, then see a prompt describing the access being requested for your reminders and account. Approving it is what authorises the link.

Read it as a permission request, not a warning. Nothing can act on your account until you approve here, and you can approve knowing it is scoped to your own reminders.

The per-client key it creates

Approving quietly creates a per-client API key in your account, dedicated to this one connection. You never see or manage it by hand, and ChatGPT uses it to act on your behalf. Because it is per-client, revoking it affects only this connection and nothing else.

This is the neat part of the design: the convenience of a key-free sign-in, with the control of a key you can cut off on its own.

Revoking access

If you ever want to disconnect, or you connected on a device you no longer use, go to reminderit.com/api-keys and revoke the key tied to that connection. Access stops immediately, and ChatGPT can no longer see or change your reminders.

To reconnect later, you simply run the OAuth sign-in again, which mints a fresh key. Revoking is not permanent; it is just you taking the access back until you choose to grant it again.

What this means in practice

Day to day you will not think about any of this. You sign in once, ChatGPT works in your account, and that is that. But knowing the shape of it means you can connect with confidence and disconnect just as easily.

The whole model is: your login, ReminderIt's key, your revoke switch. You can connect at reminderit.com and manage access at reminderit.com/api-keys.
