How to let the assistant sign in using a vault with Open Instinct

Store site logins in an encrypted vault so autofill keeps passwords out of the model.

  • Life admin
  • Intermediate
  • 60 minutes
  • From the README
  • Any agent

Credentials. Vault secrets are encrypted, but deleting the private Blob store loses the generated encryption key and rotating it requires re-encrypting stored values.

Who it is forA person who wants an agent to log in to websites for them without pasting passwords into chat.

The problemGiving an AI model your passwords puts them in its context, and you have no way to keep them out of prompts.

The outcomeSaved vault secrets are encrypted before storage, and browser autofill fills saved passwords without the model seeing them.

What you need first

  • A Vercel account on the Pro plan, since the Hobby plan cannot run the every-minute schedule
  • A Kernel account on its free plan for cloud browsers
  • A Neon account on its free plan for Postgres
  • An iMessage-capable phone to verify the managed Linq line
  • A Stripe account only if you want Link wallet purchases

Steps

  1. Deploy the app from https://github.com/Merit-Systems/OpenInstinct and sign in with your phone number.
  2. Open the vault in your deployed app and save the login for the site you need. (inferred, check the README)
  3. Keep the private Blob store intact, since deleting it loses the automatically generated encryption key.
  4. Ask the assistant to sign in to that site as part of a task.

Prompt for your agent

Using the repo Merit-Systems/OpenInstinct, deploy the app and save a login for <target site> in its vault. Expected output: confirmation that the login is saved and that a later task signs in without the password appearing in chat. Verify that the private Blob store is still present before finishing.

Caveat. The README does not describe the vault screens, so confirm the exact steps for saving a login in the deployed app before relying on them.
