Session-Bound Launch Links
One link, one lesson.
A standard launch link works for an hour, so a forwarded link can let someone in. Session-Bound Launch Links are tied to one lesson, work once and are revoked when the person leaves.
A launch link forwarded to a friend works for an hour. Links bound to one lesson, used once and revoked on leave, close that gap.
Students share launch links in group chats. Bind each link to one class, make it single-use, and revoke it when the student leaves.
Confidential trainings can’t risk a forwarded link. Links bound to one training, single-use and revoked on leave, keep the room closed.
District safety rules call for tighter access to online lessons. Links bound to one lesson, single-use and revoked on leave, meet them.
For workshops run in a Space, links bound to one workshop, used once and revoked on leave, keep access tight.
Your child’s lesson link works only for them, only once, so nobody else can join with it.

The problem
Forwarded links let people in
Standard launch links stay valid for an hour. A link forwarded or reused can let the wrong person into a lesson.
一般的な方法
Programs rely on waiting rooms and hope links aren’t shared.
How Pencil Spaces solves it
Stricter launch links than the standard one-hour token: bound to a specific lesson, single-use, and revoked when the participant leaves.
変更点
Only the right person gets in, and only once.
What we build
- One-time, lesson-bound tokens
- Revoked on leave
- Shorter lifetimes as you need them
Build time: set with you once we scope it.
What it looks like
実際には
A student’s launch link is bound to Tuesday’s 4:00 lesson. She uses it, and it’s spent. When she leaves, it’s revoked, so a forwarded copy goes nowhere.
In a 1:1 lesson
A student forwards his link to a friend, and the friend’s click goes nowhere.
In a group class
A link shared in a group chat is already used, so nobody else gets in.
In a virtual training
Links to a confidential leadership training stop working once used.
In your classroom
Links to online intervention lessons stop working after use, as the district requires.
In the training room
Remote joiners’ links stop working once they leave the workshop.
At home
A link your daughter used yesterday can’t be reused by anyone else.
