Delegate without handing over your account

An editor is someone you trust who acts on your timer with their own Twitch account. You never share your credentials, and you decide exactly what they are allowed to do.

You can take those rights back at any time, without changing anything else in your setup.

Invite an editor

Open Timers, then expand 👥 Editors under the timer in question.
Enter their Twitch username.
Tick the rights you are granting.
Click ＋ Invite.

Until they sign in for the first time, the line reads Pending first sign-in: the invitation is waiting for them, there is nothing else to do. It survives a Twitch username change, because it binds to the account at that first sign-in.

The six rights

Add time: add, remove or set the remaining time. Ticked by default.
Start / pause: start and stop the countdown.
Appearance: overlay theme, colours, font and CSS.
Goals: create and edit milestones, their sets and their style.
Time Settings: change the rate card, that is how much time each sub, bit, raid or donation adds.
Statistics: read the timer's totals, top contributors and charts. Read-only: events cannot be deleted from there.

Each right is independent: you can hand over the rate card without letting anyone touch the start button, or the other way round.

Rights are checked on every action, not just on display. Someone without a right cannot use it, even knowing the address of the page.

What your editor sees

They sign in to Marathon-Timer with their Twitch account, then open Shared with me in their menu. They find your timer there, its live time, and only the buttons matching their rights:

quick add buttons and a Set time field;
a button to start or pause;
shortcuts to appearance, goals, time settings and statistics.

The Start / pause right also covers your happy hours: the editor can start and stop them, and a badge shows the one that is running.

The page refreshes on its own: time added by your viewers shows up without reloading anything.

A banner always reminds them which timer they are working on, and who owns it.

With no rights at all, they simply read You can view this timer but not act on it.

Change or revoke access

In the same Editors section, tick or untick someone's rights and save. The cross at the end of their line removes their access entirely.

The change takes effect immediately: a page they left open will no longer let them act.

A few tips

Start small: Add time alone is enough to catch up missed events while you are streaming.
Keep Time Settings for someone who understands what a rate card does: a value changed mid-subathon is felt straight away.
Tidy up after an event: access granted for one marathon does not need to last all year.
