Access & accounts
Essarion Science is a private instrument. It is not open for registration, and every account is set up directly by Essarion. This page covers who can get in, how signing in works, and what an account includes.
01Who can use it
Only people with an account that Essarion has set up can use it. There is no sign-up page, no invitation code and no request form, and nothing in the product can create an account.
Every signed-in request is checked against an access list. An address that is not on it cannot sign in, even with the right password. If an address is removed from the list, its access ends on the next request, including any session that is already open.
02Signing in
Go to science.essarion.com and choose Sign in. Enter the email address and password for your account. You are taken to the Workbench, and a signed session cookie keeps you signed in for a period before you need to sign in again.
| Message | What it means |
|---|---|
| Invalid email or password | The email or password is wrong, or there is no account for that address. |
| This account cannot access this service. | The password was right, but the address is not on the access list. |
| Too many sign-in attempts. Please try again later | Repeated failed attempts are throttled for a short window. Wait and try again. |
There is no password reset in the product. If you cannot sign in, contact Essarion. To sign out, use the account menu in the sidebar.
03Sign in with Essarion
The sign-in page also offers Sign in with Essarion, which uses an Essarion ID instead of a password typed here. It does not create an account. It only works for an Essarion ID linked to an existing Essarion Science account on the access list.
- The first time, choose Sign in with Essarion and sign in to your Essarion ID.
- You are sent back to a linking screen for the account with the same email address. Enter that account's Essarion Science password once. The password is the proof that the account is yours.
- After that, either route signs you in.
An email address alone never links accounts. If the Essarion ID service is not available, the sign-in page says so, and email and password still work.
Essarion ID is a separate account
An Essarion ID has its own email and password, separate from your Essarion Science account. Being signed in to one does not sign you in to the other.
04What an account includes
- The whole product: the Workbench, Fold, Studio, Data and Artifacts, every tool, and every depth.
- No per-model gate and no usage cap. Usage is recorded but accounts are not limited against a monthly allowance at present.
- Your own sessions, uploaded files, artifacts and Studio projects. Sessions and projects belong to the account that created them; other accounts cannot open them.
05Terms and data
Use of Essarion Science is governed by the Terms of Service and the Privacy Policy. The software is proprietary. It is not licensed for self-hosting or redistribution.
The databases it reaches are licensed by their providers on their own terms, and some ask to be credited when their data is reused. See Provenance and credit.
06Security boundaries
The platform-wide model — credential hashing, signed sessions, transport — is described in Security. Three boundaries are specific to Science:
- Every notebook cell, the agent's or yours, passes a static check and runs with restricted builtins, an import safelist and a timeout.
- The shell sandbox, where offered, runs each command in its own process with CPU, memory, file-size and file-descriptor limits.
- Direct URL fetches can reach public addresses only. Private, loopback and cloud-metadata addresses are refused, and each redirect is checked.
All three are described in The workbench.
