How to sign in to a web admin console with a saved login and TOTP with Open Keylet

Let an agent fill a login field and a current TOTP code in the browser.

Credentials. The agent can sign in to a live account with the saved item, so confirm the target URL before the agent submits the form.

Who it is forAn admin whose agent must reach a web console that asks for a password and a six-digit authenticator code.

The problemAgents get stuck on login pages, and reading one-time codes aloud or pasting them is slow and risky.

The outcomeThe agent signs in to the admin console using the saved item, with the password and seed kept local.

What you need first

  • A Windows, macOS or Linux machine to run the OpenKeylet desktop app
  • An MCP-capable agent client such as Codex, Claude Code or Cursor
  • The target server, website or API account and its credentials
  • For browser filling on Chrome, Edge or Brave: one manual extension load on first use

Steps

  1. Download the portable build for your platform and open Open Keylet.
  2. Install the bundled Chromium extension in Chrome, Edge or Brave with its one manual load on first use.
  3. Pair the Browser Bridge from Settings.
  4. Save an item such as Admin Account with username, password and TOTP modules.
  5. Ask the agent to open the admin console and use that item name in Open Keylet MCP when credentials are required.

Prompt for your agent

Using the OpenKeylet MCP server from omaekumiko2-create/OpenKeylet, open <admin console URL> and use the item "<item name>" to fill the username, password and current TOTP code, submitting the form once. Report whether sign-in succeeded. Verify that no password or TOTP seed appears in your response.

Caveat. Open Keylet writes one selected field into the focused control and does not inspect the page, so the agent must focus the correct field first.
