# Rotating your TCGplayer login without breaking sync

> What happens to your Hoard agent's sync when you change your TCGplayer password.

Changing your TCGplayer password doesn't break anything permanently, but it does end your agent's current session — here's what to expect and what to do.

## What happens when you change your TCGplayer password

Hoard never stores your TCGplayer password. Your agent logs into TCGplayer through a real browser window, and the resulting session cookie is kept only in memory for as long as the agent process runs — it's never written to disk and TCGplayer's "Remember Me" doesn't change that. As soon as you change your password on TCGplayer's side, that in-memory session becomes invalid.

On the agent's next cycle, it detects the dead session and opens a fresh TCGplayer login window automatically, the same window it uses for any first-time or expired login. You'll need to sign in once with your new password.

## What to do

1. **Change your password on TCGplayer as normal** — nothing on the Hoard side needs to happen first.
2. **Let your agent's next cycle run**, or click **Sync Now** on your dashboard to trigger it immediately.
3. **Log in when the window appears.** A Chrome window will open to TCGplayer's login page with your new password required. Complete any CAPTCHA if one shows up.
4. That's it — no settings to update, no re-authorization with Hoard. Sync resumes normally after that login.

## Nothing else needs to change

You don't need to update any settings in Hoard, re-authorize your account, or generate a new API key just because your TCGplayer password changed. The password itself lives entirely on TCGplayer's side; Hoard's agent just needs a fresh browser login to pick up the new session.

## If the window doesn't appear

If your dashboard shows the agent stuck rather than prompting a new login, see [agent stuck on "awaiting login"](/how-to/sync/agent-stuck-on-awaiting-login) — it covers the case where a login window is open but not being detected.

## Rotating your Hoard API key

This page covers the TCGplayer side only. If you're instead rotating the Hoard bearer key your standalone CLI agent uses, that's a separate process with its own key-management flow in Hoard's settings — see [rotating your Hoard bearer key](/tutorials/rotating-your-bearer-key). The two rotations don't affect each other: changing your TCGplayer password doesn't touch your Hoard API key, and rotating your Hoard API key doesn't touch your TCGplayer session.
