# Tokens & QR codes
> Hand a volunteer a phone without giving them access to your organization.
A **timing link** turns any device into a timing device for one event. Your
volunteer scans a QR code and starts timing — no account, no password, no access
to anything else you run.
## Create one
You need to be an organization member, or hold a timing link with admin
access.
Fill in:
| Field | What to put |
| ----------------- | ----------------------------------------------------------------------------------------------------- |
| **Label** | For you, not them — "Finish line phone 1", "Sarah's phone" |
| **Roles** | What they're allowed to do. **Timer** for most volunteers — see [Who can do what](/timing/crew/roles) |
| **Expires in** | Hours from now. Set it to just past the end of your event |
| **Allowed races** | Optional. Restricts them to specific races in the event |
You see the link and QR code **once**. Screenshot it, print it, or copy it
somewhere now.
If you lose it, no harm done — revoke it and issue another.
Issue one link **per phone**, not per person. If a volunteer's phone dies and
they borrow another, you want to be able to switch off the dead one without
cutting off everyone else.
## Handing them out
Print each QR code with the volunteer's name on it and put them in envelopes.
It's the fastest possible race-morning handover: one piece of paper, one scan,
they're timing.
Or text the link. Either works.
## What your volunteer sees
They open the QR code or link on their phone and get a confirmation card showing
which organization and event they're joining and what they'll be able to do.
They tap **Continue** and they're on the timing screen.
The link saves itself on that phone, so closing the browser doesn't lock them
out. They can pick it up again all day.
## Switching one off
Click **Revoke** next to any link in the token list. That device stops working
immediately.
Anything they already recorded is unaffected — revoking access never removes
results. If they're mid-race, issue a new link and have them scan it; nothing is
lost in between.
## What a timing link can't do
* Reach any other event or race in your organization.
* See registrations, rider details, or anything financial.
* Reconfigure the timer, or wipe its data.
* Issue further links, unless you gave it the admin role.
This is enforced on Time2Bike's side, not just hidden in the interface — a
volunteer link genuinely cannot reach the rest of your organization.
